## Common Pitfalls -1. **DRIFT SDK MEMORY LEAK (CRITICAL - Fixed Nov 15, 2025, Enhanced Nov 24, 2025):** - - **Symptom:** JavaScript heap out of memory after 10+ hours runtime, Telegram bot timeouts (60s) - - **Root Cause:** Drift SDK accumulates WebSocket subscriptions over time without cleanup - - **Manifestation:** Thousands of `accountUnsubscribe error: readyState was 2 (CLOSING)` in logs - - **Heap Growth:** Normal ~200MB → 4GB+ after 10 hours → OOM crash - - **Solution (Nov 24, 2025):** Smart error-based health monitoring replaces blind timer - - **Implementation:** - * `lib/monitoring/drift-health-monitor.ts` - Tracks accountUnsubscribe errors in real-time - * `interceptWebSocketErrors()` - Patches console.error to catch SDK WebSocket errors - * **30-second sliding window:** Only restarts if 50+ errors in 30 seconds (actual problem detected) - * **Container restart via flag:** Writes `/tmp/trading-bot-restart.flag` for watch-restart.sh - * **Health API:** `GET /api/drift/health` - Check error count and health status anytime - - **Why better than blind timer:** - * Old approach: Restarted every 2 hours regardless of health (unnecessary downtime) - * New approach: Only restarts when accountUnsubscribe errors actually occur - * Faster response: 30 seconds vs up to 2 hours wait time - * Less downtime: No unnecessary restarts when SDK healthy - - **Monitoring:** Watch for `🏥 Drift health monitor started` and error threshold logs - - **Impact:** System responds to actual problems, not blind schedule - -2. **WRONG RPC PROVIDER (CRITICAL - CATASTROPHIC SYSTEM FAILURE):** - - **FINAL CONCLUSION Nov 14, 2025 (INVESTIGATION COMPLETE):** Helius is the ONLY reliable RPC provider for Drift SDK - - **Root Cause CONFIRMED:** Alchemy's rate limiting breaks Drift SDK's burst subscription pattern during initialization - - **Definitive Proof (Nov 14, 21:14 CET):** - * Created diagnostic endpoint `/api/testing/drift-init` - * Alchemy: 17-71 subscription errors EVERY init (49 avg over 5 runs), 1644ms avg init time - * Helius: 0 subscription errors EVERY init, 800ms avg init time - * See `docs/ALCHEMY_RPC_INVESTIGATION_RESULTS.md` for full test data - - - **Why Alchemy Fails:** - * Drift SDK subscribes to 30-50+ accounts simultaneously during init (burst pattern) - * Alchemy's CUPS enforcement rate limits these burst requests - * Drift SDK does NOT retry failed subscriptions - * SDK reports "initialized successfully" but with incomplete subscription set - * Subsequent operations fail/timeout due to missing account data - * Error message: "Received JSON-RPC error calling `accountSubscribe`" - - - **Why "Breakthrough" at 14:25 Wasn't Real:** - * First Alchemy test had 17-71 subscription errors (random variation) - * Sometimes gets lucky with "just enough" subscriptions for one operation - * SDK in degraded state from the start, just not obvious until second operation - * This explains why first trade "worked" but subsequent trades failed - - - **Why Helius Works:** - * Higher burst tolerance for Solana dApp subscription patterns - * Zero subscription errors during init - * Faster initialization (800ms vs 1600ms) - * Stable for continuous operations - - - **Technical Reality vs Documentation:** - * Alchemy DOES support WebSocket subscriptions (research confirmed) - * Alchemy DOES support accountSubscribe method (not -32601 error) - * BUT: Rate limit enforcement model incompatible with Drift's burst pattern - * Documentation doesn't mention burst subscription limits - - - **Production Status:** - * Using: Helius RPC (https://mainnet.helius-rpc.com/?api-key=...) - * Retry logic: 5s exponential backoff for rate limits - * System: Stable, TP1/TP2/SL working, Position Manager tracking correctly - - - **Investigation Closed:** This is DEFINITIVE. Use Helius. Do not use Alchemy. - - **Test Yourself:** `curl 'http://localhost:3001/api/testing/drift-init?rpc=alchemy'` - -3. **Prisma not generated in Docker:** Must run `npx prisma generate` in Dockerfile BEFORE `npm run build` - -4. **Wrong DATABASE_URL:** Container runtime needs `trading-bot-postgres`, Prisma CLI from host needs `localhost:5432` - -5. **Symbol format mismatch:** Always normalize with `normalizeTradingViewSymbol()` before calling Drift (applies to ALL endpoints including `/api/trading/close`) - -6. **Missing reduce-only flag:** Exit orders without `reduceOnly: true` can accidentally open new positions - -7. **Singleton violations:** Creating multiple DriftClient or Position Manager instances causes connection/state issues - -8. **Type errors with Prisma:** The Trade type from Prisma is only available AFTER `npx prisma generate` - use explicit types or `// @ts-ignore` carefully - -9. **Quality score duplication:** Signal quality calculation exists in BOTH `check-risk` and `execute` endpoints - keep logic synchronized - -10. **TP2-as-Runner configuration:** - - `takeProfit2SizePercent: 0` means "TP2 activates trailing stop, no position close" - - This creates runner of remaining % after TP1 (default 25%, configurable via TAKE_PROFIT_1_SIZE_PERCENT) - - `TAKE_PROFIT_2_PERCENT=0.7` sets TP2 trigger price, `TAKE_PROFIT_2_SIZE_PERCENT` should be 0 - - Settings UI correctly shows "TP2 activates trailing stop" with dynamic runner % calculation - -11. **P&L calculation CRITICAL:** Use actual entry vs exit price calculation, not SDK values: -```typescript -const profitPercent = this.calculateProfitPercent(trade.entryPrice, exitPrice, trade.direction) -const actualRealizedPnL = (closedSizeUSD * profitPercent) / 100 -trade.realizedPnL += actualRealizedPnL // NOT: result.realizedPnL from SDK -``` - -12. **Transaction confirmation CRITICAL:** Both `openPosition()` AND `closePosition()` MUST call `connection.confirmTransaction()` after `placePerpOrder()`. Without this, the SDK returns transaction signatures that aren't confirmed on-chain, causing "phantom trades" or "phantom closes". Always check `confirmation.value.err` before proceeding. - -13. **Execution order matters:** When creating trades via API endpoints, the order MUST be: - 1. Open position + place exit orders - 2. Save to database (`createTrade()`) - 3. Add to Position Manager (`positionManager.addTrade()`) - - If Position Manager is added before database save, race conditions occur where monitoring checks before the trade exists in DB. - -14. **New trade grace period:** Position Manager skips "external closure" detection for trades <30 seconds old because Drift positions take 5-10 seconds to propagate after opening. Without this grace period, new positions are immediately detected as "closed externally" and cancelled. - -15. **Drift minimum position sizes:** Actual minimums differ from documentation: - - SOL-PERP: 0.1 SOL (~$5-15 depending on price) - - ETH-PERP: 0.01 ETH (~$38-40 at $4000/ETH) - - BTC-PERP: 0.0001 BTC (~$10-12 at $100k/BTC) - - Always calculate: `minOrderSize × currentPrice` must exceed Drift's $4 minimum. Add buffer for price movement. - -16. **Exit reason detection bug:** Position Manager was using current price to determine exit reason, but on-chain orders filled at a DIFFERENT price in the past. Now uses `trade.tp1Hit` / `trade.tp2Hit` flags and realized P&L to correctly identify whether TP1, TP2, or SL triggered. Prevents profitable trades being mislabeled as "SL" exits. - -17. **Per-symbol cooldown:** Cooldown period is per-symbol, NOT global. ETH trade at 10:00 does NOT block SOL trade at 10:01. Each coin (SOL/ETH/BTC) has independent cooldown timer to avoid missing opportunities on different assets. - -18. **Timeframe-aware scoring crucial:** Signal quality thresholds MUST adjust for 5min vs higher timeframes: - - 5min charts naturally have lower ADX (12-22 healthy) and ATR (0.2-0.7% healthy) than daily charts - - Without timeframe awareness, valid 5min breakouts get blocked as "low quality" - - Anti-chop filter applies -20 points for extreme sideways regardless of timeframe - - Always pass `timeframe` parameter from TradingView alerts to `scoreSignalQuality()` - -19. **Price position chasing causes flip-flops:** Opening longs at 90%+ range or shorts at <10% range reliably loses money: - - Database analysis showed overnight flip-flop losses all had price position 9-94% (chasing extremes) - - These trades had valid ADX (16-18) but entered at worst possible time - - Quality scoring now penalizes -15 to -30 points for range extremes - - Prevents rapid reversals when price is already overextended - -20. **TradingView ADX minimum for 5min:** Set ADX filter to 15 (not 20+) in TradingView alerts for 5min charts: - - Higher timeframes can use ADX 20+ for strong trends - - 5min charts need lower threshold to catch valid breakouts - - Bot's quality scoring provides second-layer filtering with context-aware metrics - - Two-stage filtering (TradingView + bot) prevents both overtrading and missing valid signals - -21. **Prisma Decimal type handling:** Raw SQL queries return Prisma `Decimal` objects, not plain numbers: - - Use `any` type for numeric fields in `$queryRaw` results: `total_pnl: any` - - Convert with `Number()` before returning to frontend: `totalPnL: Number(stat.total_pnl) || 0` - - Frontend uses `.toFixed()` which doesn't exist on Decimal objects - - Applies to all aggregations: SUM(), AVG(), ROUND() - all return Decimal types - - Example: `/api/analytics/version-comparison` converts all numeric fields - -22. **ATR-based trailing stop implementation (Nov 11, 2025):** Runner system was using FIXED 0.3% trailing, causing immediate stops: - - **Problem:** At $168 SOL, 0.3% = $0.50 wiggle room. Trades with +7-9% MFE exited for losses. - - **Fix:** `trailingDistancePercent = (atrAtEntry / currentPrice * 100) × trailingStopAtrMultiplier` - - **Config:** `TRAILING_STOP_ATR_MULTIPLIER=1.5`, `MIN=0.25%`, `MAX=0.9%`, `ACTIVATION=0.5%` - - **Typical improvement:** 0.45% ATR × 1.5 = 0.675% trail ($1.13 vs $0.50 = 2.26x more room) - - **Fallback:** If `atrAtEntry` unavailable, uses clamped legacy `trailingStopPercent` - - **Log verification:** Look for "📊 ATR-based trailing: 0.0045 (0.52%) × 1.5x = 0.78%" messages - - **ActiveTrade interface:** Must include `atrAtEntry?: number` field for calculation - - See `ATR_TRAILING_STOP_FIX.md` for full details and database analysis - -23. **CreateTradeParams interface sync:** When adding new database fields to Trade model, MUST update `CreateTradeParams` interface in `lib/database/trades.ts`: - - Interface defines what parameters `createTrade()` accepts - - Must add new field to interface (e.g., `indicatorVersion?: string`) - - Must add field to Prisma create data object in `createTrade()` function - - TypeScript build will fail if endpoint passes field not in interface - - Example: indicatorVersion tracking required 3-file update (execute route.ts, CreateTradeParams interface, createTrade function) - -24. **Position.size tokens vs USD bug (CRITICAL - Fixed Nov 12, 2025):** - - **Symptom:** Position Manager detects false TP1 hits, moves SL to breakeven prematurely - - **Root Cause:** `lib/drift/client.ts` returns `position.size` as BASE ASSET TOKENS (12.28 SOL), not USD ($1,950) - - **Bug:** Comparing tokens (12.28) directly to USD ($1,950) → 12.28 < 1,950 × 0.95 = "99.4% reduction" → FALSE TP1! - - **Fix:** Always convert to USD before comparisons: - ```typescript - // In Position Manager (lines 322, 519, 558, 591) - const positionSizeUSD = Math.abs(position.size) * currentPrice - - // Now compare USD to USD - if (positionSizeUSD < trade.currentSize * 0.95) { - // Actual 5%+ reduction detected - } - ``` - - **Impact:** Without this fix, TP1 never triggers correctly, SL moves at wrong times, runner system fails - - **Where it matters:** Position Manager, any code querying Drift positions - - **Database evidence:** Trade showed `tp1Hit: true` when 100% still open, `slMovedToBreakeven: true` prematurely - -25. **Leverage display showing global config instead of symbol-specific (Fixed Nov 12, 2025):** - - **Symptom:** Telegram notifications showing "⚡ Leverage: 10x" when actual position uses 15x or 20x - - **Root Cause:** API response returning `config.leverage` (global default) instead of symbol-specific value - - **Fix:** Use actual leverage from `getPositionSizeForSymbol()`: - ```typescript - // app/api/trading/execute/route.ts (lines 345, 448, 522, 557) - const { size, leverage, enabled } = getPositionSizeForSymbol(driftSymbol, config) - - // Return symbol-specific leverage - leverage: leverage, // NOT: config.leverage - ``` - - **Impact:** Misleading notifications, user confusion about actual position risk - - **Hierarchy:** Per-symbol ENV (SOLANA_LEVERAGE) → Market config → Global ENV (LEVERAGE) → Defaults - -26. **Indicator version tracking (Nov 12, 2025+):** - - Database field `indicatorVersion` tracks which TradingView strategy generated the signal - - **v5:** Buy/Sell Signal strategy (pre-Nov 12) - - **v6:** HalfTrend + BarColor strategy (Nov 12-18) - - **v7:** v6 with toggle filters (deprecated - no fundamental improvements) - - **v8:** Money Line Sticky Trend (Nov 18+) - 0.6% flip threshold, momentum confirmation, anti-whipsaw - - Used for performance comparison between strategies (v6 vs v8 A/B testing) - -27. **Runner stop loss gap - NO protection between TP1 and TP2 (CRITICAL - Fixed Nov 15, 2025):** - - **Symptom:** Runner position remained open despite price moving far past stop loss level - - **Root Cause:** Position Manager only checked stop loss BEFORE TP1 (line 877: `if (!trade.tp1Hit && this.shouldStopLoss(...)`), creating a protection gap - - **Bug sequence:** - 1. SHORT opened, TP1 hit at 70% close (runner = 30% remaining) - 2. Runner had stop loss at profit-lock level (+0.5%) - 3. Price moved past stop loss → NO CHECK RAN (tp1Hit = true, so SL check skipped) - 4. Runner exposed to unlimited loss for hours during TP1→TP2 window - 5. Made worse by runner below Drift minimum size ($12.79 < $15) = no on-chain orders either - - **Impact:** Hours of unprotected runner exposure = potential unlimited loss on 25-30% remaining position - - **Code analysis:** - ```typescript - // Line 877: Stop loss checked ONLY before TP1 - if (!trade.tp1Hit && this.shouldStopLoss(currentPrice, trade)) { - console.log(`🔴 STOP LOSS: ${trade.symbol}`) - await this.executeExit(trade, 100, 'SL', currentPrice) - } - - // Lines 881-895: TP1 and TP2 processing - NO STOP LOSS CHECK - - // BUG: Runner between TP1-TP2 had ZERO stop loss protection! - ``` - - **Fix:** Added explicit runner stop loss check at line ~881: - ```typescript - // 2b. CRITICAL: Runner stop loss (AFTER TP1, BEFORE TP2) - // This protects the runner position after TP1 closes main position - if (trade.tp1Hit && !trade.tp2Hit && this.shouldStopLoss(currentPrice, trade)) { - console.log(`🔴 RUNNER STOP LOSS: ${trade.symbol} at ${profitPercent.toFixed(2)}% (profit lock triggered)`) - await this.executeExit(trade, 100, 'SL', currentPrice) - return - } - ``` - - **Why undetected:** Runner system relatively new (Nov 11), most trades hit TP2 quickly without price reversals - - **Compounded by:** Drift minimum size check ($15 for SOL) prevented on-chain SL orders for small runners - - **Log warning:** `⚠️ SL size below market min, skipping on-chain SL` indicates runner has NO on-chain protection - - **Lesson:** Every conditional branch in risk management MUST have explicit stop loss checks - never assume "it'll get caught somewhere" - -27. **External closure duplicate updates bug (CRITICAL - Fixed Nov 12, 2025):** - - **Symptom:** Trades showing 7-8x larger losses than actual ($58 loss when Drift shows $7 loss) - - **Root Cause:** Position Manager monitoring loop re-processes external closures multiple times before trade removed from activeTrades Map - - **Bug sequence:** - 1. Trade closed externally (on-chain SL order fills at -$7.98) - 2. Position Manager detects closure: `position === null` - 3. Calculates P&L and calls `updateTradeExit()` → -$7.50 in DB - 4. **BUT:** Trade still in `activeTrades` Map (removal happens after DB update) - 5. Next monitoring loop (2s later) detects closure AGAIN - 6. Accumulates P&L: `previouslyRealized (-$7.50) + runnerRealized (-$7.50) = -$15.00` - 7. Updates database AGAIN → -$15.00 in DB - 8. Repeats 8 times → final -$58.43 (8× the actual loss) - - **Fix:** Remove trade from `activeTrades` Map BEFORE database update: - ```typescript - // BEFORE (BROKEN): - await updateTradeExit({ ... }) - await this.removeTrade(trade.id) // Too late! Loop already ran again - - // AFTER (FIXED): - this.activeTrades.delete(trade.id) // Remove FIRST - await updateTradeExit({ ... }) // Then update DB - if (this.activeTrades.size === 0) { - this.stopMonitoring() - } - ``` - - **Impact:** Without this fix, every external closure is recorded 5-8 times with compounding P&L - - **Root cause:** Async timing issue - `removeTrade()` is async but monitoring loop continues synchronously - - **Evidence:** Logs showed 8 consecutive "External closure recorded" messages with increasing P&L - - **Line:** `lib/trading/position-manager.ts` line 493 (external closure detection block) - - Must update `CreateTradeParams` interface when adding new database fields (see pitfall #23) - - Analytics endpoint `/api/analytics/version-comparison` compares v5 vs v6 performance - -28. **Signal quality threshold adjustment (Nov 12, 2025):** - - **Lowered from 65 → 60** based on data analysis of 161 trades - - **Reason:** Score 60-64 tier outperformed higher scores: - - 60-64: 2 trades, +$45.78 total, 100% WR, +$22.89 avg - - 65-69: 13 trades, +$28.28 total, 53.8% WR, +$2.18 avg - - 70-79: 67 trades, +$8.28 total, 44.8% WR (worst performance!) - - **Paradox:** Higher quality scores don't correlate with better performance in current data - - **Expected impact:** 2-3 additional trades/week, +$46-69 weekly profit potential - - **Data collection:** Enables blocked signals at 55-59 range for Phase 2 optimization - - **Risk:** Small sample size (2 trades) could be outliers, but downside limited - - SQL analysis showed clear pattern: stricter filtering was blocking profitable setups - -29. **Database-First Pattern (CRITICAL - Fixed Nov 13, 2025):** - - **Symptom:** Positions opened on Drift with NO database record, NO Position Manager tracking, NO TP/SL protection - - **Root Cause:** Execute endpoint saved to database AFTER adding to Position Manager, with silent error catch - - **Bug sequence:** - 1. TradingView signal → `/api/trading/execute` - 2. Position opened on Drift ✅ - 3. Position Manager tracking added ✅ - 4. Database save attempted ❌ (fails silently) - 5. API returns success to user ❌ - 6. Container restarts → Position Manager loses in-memory state ❌ - 7. Result: Unprotected position with no monitoring or TP/SL orders - - **Fix:** Database-first execution order in `app/api/trading/execute/route.ts`: - ```typescript - // CRITICAL: Save to database FIRST before adding to Position Manager - try { - await createTrade({...}) - } catch (dbError) { - console.error('❌ CRITICAL: Failed to save trade to database:', dbError) - return NextResponse.json({ - success: false, - error: 'Database save failed - position unprotected', - message: `Position opened on Drift but database save failed. CLOSE POSITION MANUALLY IMMEDIATELY. Transaction: ${openResult.transactionSignature}`, - }, { status: 500 }) - } - - // ONLY add to Position Manager if database save succeeded - await positionManager.addTrade(activeTrade) - ``` - - **Impact:** Without this fix, ANY database failure creates unprotected positions - - **Verification:** Test trade cmhxj8qxl0000od076m21l58z (Nov 13) confirmed fix working - - **Documentation:** See `CRITICAL_INCIDENT_UNPROTECTED_POSITION.md` for full incident report - - **Rule:** Database persistence ALWAYS comes before in-memory state updates - -30. **DNS retry logic (Nov 13, 2025):** - - **Problem:** Trading bot fails with "fetch failed" errors when DNS resolution temporarily fails for `mainnet.helius-rpc.com` - - **Impact:** n8n workflow failures, missed trades, container restart failures - - **Root Cause:** `EAI_AGAIN` errors are transient DNS issues that resolve in seconds, but bot treated them as permanent failures - - **Fix:** Automatic retry in `lib/drift/client.ts` - `retryOperation()` wrapper: - ```typescript - // Detects transient errors: fetch failed, EAI_AGAIN, ENOTFOUND, ETIMEDOUT - // Retries up to 3 times with 2s delay between attempts (DNS-specific, separate from rate limit retries) - // Fails fast on non-transient errors (auth, config, permanent network issues) - await this.retryOperation(async () => { - // Initialize Drift SDK, subscribe, get user account - }, 3, 2000, 'Drift initialization') - ``` - - **Success logs:** `⚠️ Drift initialization failed (attempt 1/3): fetch failed` → `⏳ Retrying in 2000ms...` → `✅ Drift service initialized successfully` - - **Impact:** 99% of transient DNS failures now auto-recover, preventing missed trades - - **Note:** DNS retries use 2s delays (fast recovery), rate limit retries use 5s delays (RPC cooldown) - - **Documentation:** See `docs/DNS_RETRY_LOGIC.md` for monitoring queries and metrics - -31. **Declaring fixes "working" before deployment (CRITICAL - Nov 13, 2025):** - - **Symptom:** AI says "position is protected" or "fix is deployed" when container still running old code - - **Root Cause:** Conflating "code committed to git" with "code running in production" - - **Real Incident:** Database-first fix committed 15:56, declared "working" at 19:42, but container started 15:06 (old code) - - **Result:** Unprotected position opened, database save failed silently, Position Manager never tracked it - - **Financial Impact:** User discovered $250+ unprotected position 3.5 hours after opening - - **Verification Required:** - ```bash - # ALWAYS check before declaring fix deployed: - docker logs trading-bot-v4 | grep "Server starting" | head -1 - # Compare container start time to git commit timestamp - # If container older: FIX NOT DEPLOYED - ``` - - **Rule:** NEVER say "fixed", "working", "protected", or "deployed" without verifying container restart timestamp - - **Impact:** This is a REAL MONEY system - premature declarations cause financial losses - - **Documentation:** Added mandatory deployment verification to VERIFICATION MANDATE section - -32. **Phantom trade notification workflow breaks (Nov 14, 2025):** - - **Symptom:** Phantom trade detected, position opened on Drift, but n8n workflow stops with HTTP 500 error. User NOT notified. - - **Root Cause:** Execute endpoint returned HTTP 500 when phantom detected, causing n8n chain to halt before Telegram notification - - **Problem:** Unmonitored phantom position on exchange while user is asleep/away = unlimited risk exposure - - **Fix:** Auto-close phantom trades immediately + return HTTP 200 with warning (allows n8n to continue) - ```typescript - // When phantom detected in app/api/trading/execute/route.ts: - // 1. Immediately close position via closePosition() - // 2. Save to database (create trade + update with exit info) - // 3. Return HTTP 200 with full notification message in response - // 4. n8n workflow continues to Telegram notification step - ``` - - **Response format change:** `{ success: true, warning: 'Phantom trade detected and auto-closed', isPhantom: true, message: '[Full notification text]', phantomDetails: {...} }` - - **Why auto-close:** User can't always respond (sleeping, no phone, traveling). Better to exit with small loss/gain than leave unmonitored position exposed. - - **Impact:** Protects user from unlimited risk during unavailable hours. Phantom trades are rare edge cases (oracle issues, exchange rejections). - - **Database tracking:** `status='phantom'`, `exitReason='manual'`, enables analysis of phantom frequency and patterns - -33. **Wrong entry price after orphaned position restoration (CRITICAL - Fixed Nov 15, 2025):** - - **Symptom:** Position Manager tracking SHORT at $141.51 entry, but Drift UI shows $141.31 actual entry - - **Root Cause:** Startup validation restored orphaned position but used OLD database entry price instead of querying Drift for real value - - **Bug sequence:** - 1. Position opened at $141.317 (per Drift order history) - 2. TP1 closed 70% at $140.942 - 3. Database incorrectly saved entry as $141.508 (maybe averaged or from previous position) - 4. Container restart → startup validation found position on Drift - 5. Reopened trade in DB but used stale `trade.entryPrice` from database - 6. Position Manager tracked with wrong entry ($141.51 vs actual $141.31) - 7. Stop loss calculated from wrong base: $141.08 instead of $140.89 - - **Impact:** 0.14% difference ($0.20/SOL) in SL placement - could mean difference between small profit and small loss - - **Fix:** Query Drift SDK for actual entry price during orphaned position restoration - ```typescript - // In lib/startup/init-position-manager.ts (line 121-144): - // When reopening closed trade found on Drift: - const currentPrice = await driftService.getOraclePrice(marketConfig.driftMarketIndex) - const positionSizeUSD = position.size * currentPrice - - await prisma.trade.update({ - where: { id: trade.id }, - data: { - status: 'open', - exitReason: null, - entryPrice: position.entryPrice, // CRITICAL: Use Drift's actual entry price - positionSizeUSD: positionSizeUSD, // Update to current size (runner after TP1) - } - }) - ``` - - **Drift SDK returns real entry:** `position.entryPrice` from `getPosition()` calculates from on-chain data (quoteAssetAmount / baseAssetAmount) - - **Future-proofed:** All orphaned position restorations now use authoritative Drift entry price, not stale DB value - - **Manual fix required once:** Had to manually UPDATE database for existing position, then restart container - - **Lesson:** Always prefer on-chain data over cached database values for critical trading parameters - -34. **Runner stop loss gap - NO protection between TP1 and TP2 (CRITICAL - Fixed Nov 15, 2025):** - - **Symptom:** Runner position remained open despite price moving far above stop loss level - - **Root Cause:** Position Manager only checked stop loss BEFORE TP1 hit (line 693) OR AFTER TP2 hit (line 835), creating a gap - - **Bug sequence:** - 1.

Position closed externally (on-chain TP/SL order fills) - 2. Position Manager attempts database update but fails silently - 3. Trade remains in database with `exitReason IS NULL` - 4. Container restart → Position Manager restores "open" trade from DB - 5. Position doesn't exist on Drift but is tracked in memory = ghost position - 6. Accumulates over time: 1 ghost → 2 ghosts → 4+ ghosts - 7. Each ghost triggers monitoring, order updates, price checks - 8. RPC rate limit exhaustion → 429 errors → system instability - - **Real incidents:** - * Nov 14: Untracked 0.09 SOL position with no TP/SL protection - * Nov 15 19:01: Position Manager tracking 4+ ghosts, massive rate limiting, "vanishing orders" - * After cleanup: 4+ ghosts → 1 actual position, system stable - - **Why manual restarts worked:** Forced Position Manager to re-query Drift, but didn't prevent recurrence - - **Solution:** Periodic Drift position validation (Nov 15, 2025) - ```typescript - // In lib/trading/position-manager.ts: - - // Schedule validation every 5 minutes - private scheduleValidation(): void { - this.validationInterval = setInterval(async () => { - await this.validatePositions() - }, 5 * 60 * 1000) - } - - // Validate tracked positions against Drift reality - private async validatePositions(): Promise { - for (const [tradeId, trade] of this.activeTrades) { - const position = await driftService.getPosition(marketConfig.driftMarketIndex) - - // Ghost detected: tracked but missing on Drift - if (!position || Math.abs(position.size) < 0.01) { - console.log(`🔴 Ghost position detected: ${trade.symbol}`) - await this.handleExternalClosure(trade, 'Ghost position cleanup') - } - } - } - - // Reusable ghost cleanup method - private async handleExternalClosure(trade: ActiveTrade, reason: string): Promise { - // Remove from monitoring FIRST (prevent race conditions) - this.activeTrades.delete(trade.id) - - // Update database with estimated P&L - await updateTradeExit({ - positionId: trade.positionId, - exitPrice: trade.lastPrice, - exitReason: 'manual', // Ghost closures = manual - realizedPnL: estimatedPnL, - exitOrderTx: reason, // Store cleanup reason - ... - }) - - if (this.activeTrades.size === 0) { - this.stopMonitoring() - } - } - ``` - - **Behavior:** Auto-detects and cleans ghosts every 5 minutes, no manual intervention - - **RPC overhead:** Minimal (1 check per 5 min per position = ~288 calls/day for 1 position) - - **Benefits:** - * Self-healing system prevents ghost accumulation - * Eliminates rate limit storms from ghost management - * No more manual container restarts needed - * Addresses root cause (state management) not symptom (rate limits) - - **Logs:** `🔍 Scheduled position validation every 5 minutes` on startup - - **Monitoring:** `🔴 Ghost position detected` + `✅ Ghost position cleaned up` in logs - - **Verification:** Container restart shows 1 position, not 4+ like before - - **Why paid RPC doesn't fix this:** Ghost positions are state management bug, not capacity issue - - **Lesson:** Periodic validation of in-memory state against authoritative source prevents state drift - -39. **Settings UI permission error - .env file not writable by container user (CRITICAL - Fixed Nov 15, 2025):** - - **Symptom:** Settings UI save fails with "Failed to save new settings" error - - **Root Cause:** .env file on host owned by root:root, nextjs user (UID 1001) inside container has read-only access - - **Impact:** Users cannot adjust ANY configuration via settings UI (position size, leverage, TP/SL levels, etc.) - - **Error message:** `EACCES: permission denied, open '/app/.env'` (errno -13, syscall 'open') - - **User escalation:** "thats a major flaw. THIS NEEDS TO WORK." - - **Why it happens:** - 1. Docker mounts .env file from host: `./.env:/app/.env` (docker-compose.yml line 62) - 2. Mounted files retain host ownership (root:root on host = root:root in container) - 3. Container runs as nextjs user (UID 1001) for security - 4. Settings API attempts `fs.writeFileSync('/app/.env')` → permission denied - - **Attempted fix (FAILED):** `docker exec trading-bot-v4 chown nextjs:nodejs /app/.env` - * Error: "Operation not permitted" - cannot change ownership on mounted files from inside container - - **Correct fix:** Change ownership on HOST before container starts - ```bash - # On host as root - chown 1001:1001 /home/icke/traderv4/.env - chmod 644 /home/icke/traderv4/.env - - # Restart container to pick up new permissions - docker compose restart trading-bot - - # Verify inside container - docker exec trading-bot-v4 ls -la /app/.env - # Should show: -rw-r--r-- 1 nextjs nodejs - ``` - - **Why UID 1001:** Matches nextjs user created in Dockerfile: - ```dockerfile - RUN addgroup --system --gid 1001 nodejs && \ - adduser --system --uid 1001 nextjs - ``` - - **Verification:** Settings UI now saves successfully, .env file updated with new values - - **Impact:** Restores full settings UI functionality - users can adjust position sizing, leverage, TP/SL percentages - - **Alternative solution (NOT used):** Copy .env during Docker build with `COPY --chown=nextjs:nodejs`, but this breaks runtime config updates - - **Lesson:** Docker volume mounts retain host ownership - must plan for writability by setting host file ownership to match container user UID - -40. **Ghost position death spiral from skipped validation (CRITICAL - Fixed Nov 15, 2025, REFACTORED Nov 16, 2025):** - - **Symptom:** Telegram /status shows 2 open positions when database shows all closed, massive rate limit storms (100+ RPC calls/minute) - - **Root Cause:** Periodic validation (every 5min) SKIPPED when Drift service rate-limited: `⏳ Drift service not ready, skipping validation` - - **Death Spiral:** Ghosts → rate limits → validation skipped → more rate limits → more ghosts - - **Impact:** System unusable, requires manual container restart, user can't be away from laptop - - **User Requirement:** "bot has to work all the time especially when i am not on my laptop" - MUST be fully autonomous - - **Real Incident (Nov 15, 2025):** - * Position Manager tracking 2 ghost positions - * Both positions closed on Drift but still in memory - * Trying to close non-existent positions every 2 seconds - * Rate limit exhaustion prevented validation from running - * Only solution was container restart (not autonomous) - - **REFACTORED Solution (Nov 16, 2025) - Drift API only:** - * User feedback: Time-based cleanup (6 hours) too aggressive for legitimate long-running positions - * **Removed Layer 1** (age-based cleanup) - could close valid positions prematurely - * **All ghost detection now uses Drift API as source of truth** - * Layer 2: Queries Drift after 20 failed close attempts to verify position exists - * Layer 3: Queries Drift every 40s during monitoring (unchanged) - * Periodic validation: Queries Drift every 5 minutes for all tracked positions - * Commit: 9db5f85 "refactor: Remove time-based ghost detection, rely purely on Drift API" - - **Original 3-layer protection system (Nov 15, 2025 - DEPRECATED):** - ```typescript - // LAYER 1: Database-based age check (doesn't require RPC) - private async cleanupStalePositions(): Promise { - const sixHoursAgo = Date.now() - (6 * 60 * 60 * 1000) - - for (const [tradeId, trade] of this.activeTrades) { - if (trade.entryTime < sixHoursAgo) { - console.log(`🔴 STALE GHOST DETECTED: ${trade.symbol} (age: ${hours}h)`) - await this.handleExternalClosure(trade, 'Stale position cleanup (>6h old)') - } - } - } - - // LAYER 2: Death spiral detector in executeExit() - if (errorMsg.includes('429')) { - if (trade.priceCheckCount > 20) { // 20+ failed close attempts (40+ seconds) - console.log(`🔴 DEATH SPIRAL DETECTED: ${trade.symbol}`) - await this.handleExternalClosure(trade, 'Death spiral prevention') - return // Force remove from monitoring - } - } - - // LAYER 3: Ghost check during normal monitoring (every 20 price updates) - if (trade.priceCheckCount % 20 === 0) { - const position = await driftService.getPosition(marketConfig.driftMarketIndex) - if (!position || Math.abs(position.size) < 0.01) { - console.log(`🔴 GHOST DETECTED in monitoring loop`) - await this.handleExternalClosure(trade, 'Ghost detected during monitoring') - return - } - } - ``` - - **Key Changes:** - * validatePositions() now runs database cleanup FIRST (Layer 1) before Drift RPC checks - * Changed skip message from "skipping validation" to "using database-only validation" - * Layer 1 ALWAYS runs (no RPC required) - prevents long-term ghost accumulation (>6h) - * Layer 2 breaks death spirals within 40 seconds of detection - * Layer 3 catches ghosts quickly during normal monitoring (every 40s vs 5min) - - **Impact:** - * System now self-healing - no manual intervention needed - * Ghost positions cleaned within 40-360 seconds (depending on layer) - * Works even during severe rate limiting (Layer 1 doesn't need RPC) - * Telegram /status always accurate - * User can be away - bot handles itself autonomously - - **Verification:** Container restart + new code = no more ghost accumulation possible - - **Lesson:** Critical validation logic must NEVER skip during error conditions - use fallback methods that don't require the failing resource - -41. **Stats API recalculating P&L incorrectly for TP1+runner trades (CRITICAL - Fixed Nov 19, 2025):** - - **Symptom:** Withdrawal stats page showing -$26.10 P&L when Drift UI shows +$46.97 - - **Root Cause:** Stats API recalculating P&L from entry/exit prices, which doesn't work for TP1+runner partial closes - - **The Problem:** - * Each trade has 2 closes: TP1 (60-75%) at one price, runner (25-40%) at different price - * Database stores combined P&L from both closes in `realizedPnL` field - * Stats API used `positionSizeUSD × (exit - entry) / entry` formula - * But `exitPrice` is AVERAGE of TP1 and runner exits, not actual exit prices - * Formula: `(TP1_price × 0.6 + runner_price × 0.4) / 1.0` = average exit - * Result: Incorrect P&L calculation (-$26.10 vs actual +$46.97) - - **Real Example:** - * Trade: Entry $138.36 → TP1 $137.66 (60%) + Runner $136.94 (40%) - * Database: Combined P&L $54.19 (from Drift: $22.78 TP1 + $31.41 runner) - * Stats recalc: $8,326 × (136.96 - 138.36) / 138.36 = $83.94 (wrong!) - * Correct: Use database `realizedPnL` $54.19 directly - - **Drift UI shows 10 lines for 5 trades:** - * Each trade = 2 lines (TP1 close + runner close) - * Line 1: TP1 60% at $137.66 = $22.78 - * Line 2: Runner 40% at $136.94 = $31.41 - * Total: $54.19 (stored in database `realizedPnL`) - - **Fix (Nov 19, 2025):** - ```typescript - // BEFORE (BROKEN - recalculated from entry/exit): - const totalPnL = trades.reduce((sum, trade) => { - const correctPnL = trade.positionSizeUSD * ( - trade.direction === 'long' - ? (trade.exitPrice - trade.entryPrice) / trade.entryPrice - : (trade.entryPrice - trade.exitPrice) / trade.entryPrice - ) - return sum + correctPnL - }, 0) - - // AFTER (FIXED - use database realizedPnL): - const totalPnL = trades.reduce((sum, trade) => { - return sum + Number(trade.realizedPnL) - }, 0) - ``` - - **Database P&L Correction (Nov 19, 2025):** - * Corrected inflated P&L values to match Drift UI actual TP1+runner sums - * Trade cmi5p09y: 37.67 → 38.90 (TP1 $9.72 + runner $29.18) - * Trade cmi5ie3c: 59.35 → 40.09 (TP1 $21.67 + runner $18.42) - * Trade cmi5a6jm: 19.79 → 13.72 (TP1 $1.33 + runner $4.08 + $8.31) - * v8 total: $46.97 (matches Drift UI exactly) - * Commit: cd6f590 "fix: Correct v8 trade P&L to match Drift UI actual values" - - **Impact:** Stats page now shows accurate v8 performance (+$46.97) - - **Files Changed:** - * `app/api/withdrawals/stats/route.ts` - Use `realizedPnL` not recalculation - * Added debug logging: "📊 Stats API: Found X closed trades" - * Commit: d8b0307 "fix: Use database realizedPnL instead of recalculating" - - **Lesson:** When trades have partial closes (TP1/TP2/runner), the database `realizedPnL` is the source of truth. Entry/exit price calculations only work for full position closes. Average exit price × full size ≠ sum of partial close P&Ls. - -42. **Missing Telegram notifications for position closures (Fixed Nov 16, 2025):** - - **Symptom:** Position Manager closes trades (TP/SL/manual) but user gets no immediate notification - - **Root Cause:** TODO comment in Position Manager for Telegram notifications, never implemented - - **Impact:** User unaware of P&L outcomes until checking dashboard or Drift UI manually - - **User Request:** "sure" when asked if Telegram notifications would be useful - - **Solution:** Implemented direct Telegram API notifications in lib/notifications/telegram.ts - ```typescript - // lib/notifications/telegram.ts (NEW FILE - Nov 16, 2025) - export async function sendPositionClosedNotification(options: TelegramNotificationOptions): Promise { - try { - const message = formatPositionClosedMessage(options) - - const response = await fetch( - `https://api.telegram.org/bot${process.env.TELEGRAM_BOT_TOKEN}/sendMessage`, - { - method: 'POST', - headers: { 'Content-Type': 'application/json' }, - body: JSON.stringify({ - chat_id: process.env.TELEGRAM_CHAT_ID, - text: message, - parse_mode: 'HTML' - }) - } - ) - - if (!response.ok) { - console.error('❌ Failed to send Telegram notification:', await response.text()) - } else { - console.log('✅ Telegram notification sent successfully') - } - } catch (error) { - console.error('❌ Error sending Telegram notification:', error) - // Don't throw - notification failure shouldn't break position closing - } - } - ``` - - **Message format:** Includes symbol, direction, P&L ($ and %), entry/exit prices, hold time, MAE/MFE, exit reason - - **Exit reason emojis:** TP1/TP2 (🎯), SL (🛑), manual (👤), emergency (🚨), ghost (👻) - - **Integration points:** Position Manager executeExit() (full close) + handleExternalClosure() (ghost cleanup) - - **Benefits:** - * Immediate P&L feedback without checking dashboard - * Works even when user away from computer - * No n8n dependency - direct Telegram API call - * Includes max gain/drawdown for post-trade analysis - - **Error handling:** Notification failures logged but don't prevent position closing - - **Configuration:** Requires TELEGRAM_BOT_TOKEN and TELEGRAM_CHAT_ID in .env - - **Git commit:** b1ca454 "feat: Add Telegram notifications for position closures" - - **Lesson:** User feedback channels (notifications) are as important as monitoring logic - -43. **Runner trailing stop never activates after TP1 (CRITICAL - Fixed Nov 20, 2025):** - - **Symptom:** Runner after TP1 exposed to full reversal with only static SL, no trailing protection - - **Real incident (Nov 20, $224 profit at risk):** - * LONG SOL-PERP: Entry $135.22, quality score 95, ADX 26.9 - * TP1 hit: 60% closed at $136.26 for $6.28 profit - * Runner: 40% remaining, price rose to $143.50 (+$224.49 profit) - * Runner SL: Stayed at $134.48 (-0.55% ADX-based) - NEVER trailed - * Risk: $224 profit exposed to full reversal back to -$1.55 loss - * User action: Manually closed at $143.50 to protect profit - - **Root Cause:** Position Manager detected full closure before checking TP2 price trigger - - **Bug sequence:** - 1. TP1 filled on-chain at $136.26 (60% closed) - 2. Position Manager detected size reduction, moved runner SL to $134.48 ✅ - 3. Price rose to $143.50 but monitoring detected position fully gone ❌ - 4. External closure handler stopped all monitoring before TP2 check ❌ - 5. Trailing stop NEVER activated (requires tp2Hit flag set) - 6. Runner had static SL $9.02 below current price with NO trailing - - **Three-part fix (Nov 20, 2025):** - ```typescript - // Part 1: TP2 pre-check BEFORE external closure detection (lines 776-799) - if (trade.tp1Hit && !trade.tp2Hit && !trade.closingInProgress) { - const reachedTP2 = this.shouldTakeProfit2(currentPrice, trade) - if (reachedTP2) { - console.log(`🎊 TP2 PRICE REACHED: Activating trailing stop for runner`) - trade.tp2Hit = true - trade.trailingStopActive = true - trade.peakPrice = currentPrice // Initialize for trailing - await this.saveTradeState(trade) - } - } - - // Part 2: Enhanced diagnostics (lines 803-821) - if ((position === null) && trade.tp1Hit && !trade.tp2Hit) { - console.log(`⚠️ RUNNER CLOSED EXTERNALLY without reaching TP2`) - const reachedTP2 = currentPrice >= trade.tp2Price - if (reachedTP2) { - console.log(` Price reached TP2 but tp2Hit was false!`) - console.log(` Trailing stop should have been active`) - } - } - - // Part 3: Trailing stop-aware exit reason (lines 858-877) - if (trade.tp2Hit && trade.trailingStopActive) { - const isPullback = currentPrice < trade.peakPrice * 0.99 - exitReason = isPullback ? 'SL' : 'TP2' // Trailing hit vs peak close - } - ``` - - **How it works now:** - 1. TP1 closes 60% → Runner SL moves to $134.48 (ADX-based) - 2. **Before external closure check**: System checks if price ≥ TP2 ($137.30) - 3. If yes: Sets tp2Hit=true, trailingStopActive=true, initializes peakPrice - 4. As price rises: Trailing stop moves SL up dynamically (ATR × ADX multiplier) - 5. On pullback: Trailing stop triggers, locks in profit - 6. Fully autonomous: No manual intervention needed - - **Impact:** Runner system now works as designed - "let winners run" with protection - - **User requirement:** "bot has to work all the time especially when i am not on my laptop" - - **Files:** lib/trading/position-manager.ts (3 strategic fixes) - - **Git commit:** 55582a4 "critical: Fix runner trailing stop protection after TP1" - - **Lesson:** When detecting external closures, always check for intermediate state triggers (TP2) BEFORE assuming trade is fully done. Trailing stop requires tp2Hit flag but position can close before monitoring detects TP2 price crossed. - -44. **Telegram bot DNS resolution failures (Fixed Nov 16, 2025):** - - **Symptom:** Telegram bot throws "Failed to resolve 'trading-bot-v4'" errors on /status and manual trades - - **Root Cause:** Python urllib3 has transient DNS resolution failures (same as Node.js fetch failures) - - **Error message:** `urllib3.exceptions.NameResolutionError: Failed to resolve 'trading-bot-v4'` - - **Impact:** User cannot get position status or execute manual trades via Telegram commands - - **User Request:** "we have a dns problem with the bit. can you configure it to use googles dns please" - - **Solution:** Added retry logic with exponential backoff (Python version of Node.js retryOperation pattern) - ```python - # telegram_command_bot.py (Nov 16, 2025) - def retry_request(func, max_retries=3, initial_delay=2): - """Retry a request function with exponential backoff for transient errors.""" - for attempt in range(max_retries): - try: - return func() - except (requests.exceptions.ConnectionError, - requests.exceptions.Timeout, - Exception) as e: - error_msg = str(e).lower() - if 'name or service not known' in error_msg or \ - 'failed to resolve' in error_msg or \ - 'connection' in error_msg: - if attempt < max_retries - 1: - delay = initial_delay * (2 ** attempt) - print(f"⏳ DNS/connection error (attempt {attempt + 1}/{max_retries}): {e}") - time.sleep(delay) - continue - raise - raise Exception(f"Max retries ({max_retries}) exceeded") - - # Usage in /status command: - response = retry_request(lambda: requests.get(url, headers=headers, timeout=60)) - - # Usage in manual trade execution: - response = retry_request(lambda: requests.post(url, json=payload, headers=headers, timeout=60)) - ``` - - **Retry pattern:** 3 attempts with exponential backoff (2s → 4s → 8s) - - **Matches Node.js pattern:** Same retry count and backoff as lib/drift/client.ts retryOperation() - - **Applied to:** /status command and manual trade execution (most critical paths) - - **Why not Google DNS:** DNS config changes would affect entire container, retry logic scoped to bot only - - **Success rate:** 99%+ of transient DNS failures auto-recover within 2 retries - - **Logs:** Shows "⏳ DNS/connection error (attempt X/3)" when retrying - - **Git commit:** bdf1be1 "fix: Add DNS retry logic to Telegram bot" - - **Lesson:** Python urllib3 has same transient DNS issues as Node.js - apply same retry pattern - -45. **Drift SDK position.entryPrice RECALCULATES after partial closes (CRITICAL - FINANCIAL LOSS BUG - Fixed Nov 16, 2025):** - - **Symptom:** Breakeven SL set $1.50+ ABOVE actual entry price, guaranteeing loss if triggered - - **Root Cause:** Drift SDK's `position.entryPrice` returns COST BASIS of remaining position after TP1, NOT original entry - - **Real incident (Nov 16, 02:47 CET):** - * SHORT opened at $138.52 entry - * TP1 hit, 70% closed at profit - * System queried Drift for "actual entry": returned $140.01 (runner's cost basis) - * Breakeven SL set at $140.01 (instead of $138.52) - * Result: "Breakeven" SL $1.50 ABOVE entry = guaranteed $2.52 loss if hit - * Position closed by ghost detection before SL could trigger (lucky) - - **Why Drift recalculates:** - * After partial close, remaining position has different realized P&L - * SDK calculates: `position.entryPrice = quoteAssetAmount / baseAssetAmount` - * This gives AVERAGE price of remaining position, not ORIGINAL entry - * For runners after TP1, this is ALWAYS wrong for breakeven calculation - - **Impact:** Every TP1 → breakeven SL transition uses wrong price, locks in losses instead of breakeven - - **Fix:** Always use database `trade.entryPrice` for breakeven SL (line 513 in position-manager.ts) - ```typescript - // BEFORE (BROKEN): - const actualEntryPrice = position.entryPrice || trade.entryPrice - trade.stopLossPrice = actualEntryPrice - - // AFTER (FIXED): - const breakevenPrice = trade.entryPrice // Use ORIGINAL entry from database - console.log(`📊 Breakeven SL: Using original entry price $${breakevenPrice.toFixed(4)} (Drift shows $${position.entryPrice.toFixed(4)} for remaining position)`) - trade.stopLossPrice = breakevenPrice - ``` - - **Common Pitfall #44 context:** Original fix (528a0f4) tried to use Drift's entry for "accuracy" but introduced this bug - - **Lesson:** Drift SDK data is authoritative for CURRENT state, but database is authoritative for ORIGINAL entry - - **Verification:** After TP1, logs now show: "Using original entry price $138.52 (Drift shows $140.01 for remaining position)" - - **Git commit:** [pending] "critical: Use database entry price for breakeven SL, not Drift's recalculated value" - -44. **Drift account leverage must be set in UI, not via API (CRITICAL - Nov 16, 2025):** - - **Symptom:** InsufficientCollateral errors when opening positions despite bot configured for 15x leverage - - **Root Cause:** Drift Protocol account leverage is an on-chain account setting, cannot be changed via SDK/API - - **Error message:** `AnchorError occurred. Error Code: InsufficientCollateral. Error Number: 6003. Error Message: Insufficient collateral.` - - **Real incident:** Bot trying to open $1,281 notional position with $85.41 collateral - - **Diagnosis logs:** - ``` - Program log: total_collateral=85410503 ($85.41) - Program log: margin_requirement=1280995695 ($1,280.99) - ``` - - **Math:** $1,281 notional / $85.41 collateral = 15x leverage attempt - - **Problem:** Account leverage setting was 1x (or 0x shown when no positions), NOT 15x as intended - - **Confusion points:** - 1. Order leverage dropdown in Drift UI: Shows 15x selected but this is PER-ORDER, not account-wide - 2. "Account Leverage" field at bottom: Shows "0x" when no positions open, but means 1x actual setting - 3. SDK/API cannot change: Must use Drift UI settings or account page to change on-chain setting - - **Screenshot evidence:** User showed 15x selected in dropdown, but "Account Leverage: 0x" at bottom - - **Explanation:** Dropdown is for manual order placement, doesn't affect API trades or account-level setting - - **Temporary workaround:** Reduced SOLANA_POSITION_SIZE from 100% to 6% (~$5 positions) - ```bash - # Temporary fix (Nov 16, 2025): - sed -i '378s/SOLANA_POSITION_SIZE=100/SOLANA_POSITION_SIZE=6/' /home/icke/traderv4/.env - docker restart trading-bot-v4 - - # Math: $85.41 × 6% = $5.12 position × 15x order leverage = $76.80 notional - # Fits in $85.41 collateral at 1x account leverage - ``` - - **User action required:** - 1. Go to Drift UI → Settings or Account page - 2. Find "Account Leverage" setting (currently 1x) - 3. Change to 15x (or desired leverage) - 4. Confirm on-chain transaction (costs SOL for gas) - 5. Verify setting updated in UI - 6. Once confirmed: Revert SOLANA_POSITION_SIZE back to 100% - 7. Restart bot: `docker restart trading-bot-v4` - - **Impact:** Bot cannot trade at full capacity until account leverage fixed - - **Why API can't change:** Account leverage is on-chain Drift account setting, requires signed transaction from wallet - - **Bot leverage config:** SOLANA_LEVERAGE=15 is for ORDER placement, assumes account leverage already set - - **Drift documentation:** Account leverage must be set in UI, is persistent on-chain setting - - **Lesson:** On-chain account settings cannot be changed via API - always verify account state matches bot assumptions before production trading - -45. **DEPRECATED - See Common Pitfall #43 for the actual bug (Nov 16, 2025):** - - **Original diagnosis was WRONG:** Thought database entry was stale, so used Drift's position.entryPrice - - **Reality:** Drift's position.entryPrice RECALCULATES after partial closes (cost basis of runner, not original entry) - - **Real fix:** Always use DATABASE entry price for breakeven - it's authoritative for original entry - - **This "fix" (commit 528a0f4) INTRODUCED the critical bug in Common Pitfall #43** - - **See Common Pitfall #43 for full details of the financial loss bug this caused** - -46. **100% position sizing causes InsufficientCollateral (Fixed Nov 16, 2025):** - - **Symptom:** Bot configured for 100% position size gets InsufficientCollateral errors, but Drift UI can open same size position - - **Root Cause:** Drift's margin calculation includes fees, slippage buffers, and rounding - exact 100% leaves no room - - **Error details:** - ``` - Program log: total_collateral=85547535 ($85.55) - Program log: margin_requirement=85583087 ($85.58) - Error: InsufficientCollateral (shortage: $0.03) - ``` - - **Real incident (Nov 16, 01:50 CET):** - * Collateral: $85.55 - * Bot tries: $1,283.21 notional (100% × 15x leverage) - * Drift UI works: $1,282.57 notional (has internal safety buffer) - * Difference: $0.64 causes rejection - - **Impact:** Bot cannot trade at full capacity despite account leverage correctly set to 15x - - **Fix:** Apply 99% safety buffer automatically when user configures 100% position size - ```typescript - // In config/trading.ts calculateActualPositionSize (line ~272): - let percentDecimal = configuredSize / 100 - - // CRITICAL: Safety buffer for 100% positions - if (configuredSize >= 100) { - percentDecimal = 0.99 - console.log(`⚠️ Applying 99% safety buffer for 100% position`) - } - - const calculatedSize = freeCollateral * percentDecimal - // $85.55 × 99% = $84.69 (leaves $0.86 for fees/slippage) - ``` - - **Result:** $84.69 × 15x = $1,270.35 notional (well within margin requirements) - - **User experience:** Transparent - bot logs "Applying 99% safety buffer" when triggered - - **Why Drift UI works:** Has internal safety calculations that bot must replicate externally - - **Math proof:** 1% buffer on $85 = $0.85 safety margin (covers typical fees of $0.03-0.10) - - **Git commit:** 7129cbf "fix: Add 99% safety buffer for 100% position sizing" - - **Lesson:** When integrating with DEX protocols, never use 100% of resources - always leave safety margin for protocol-level calculations - -47. **Position close verification gap - 6 hours unmonitored (CRITICAL - Fixed Nov 16, 2025):** - - **Symptom:** Close transaction confirmed on-chain, database marked "SL closed", but position stayed open on Drift for 6+ hours unmonitored - - **Root Cause:** Transaction confirmation ≠ Drift internal state updated immediately (5-10 second propagation delay) - - **Real incident (Nov 16, 02:51 CET):** - * Trailing stop triggered at 02:51:57 - * Close transaction confirmed on-chain ✅ - * Position Manager immediately queried Drift → still showed open (stale state) - * Ghost detection eventually marked it "closed" in database - * But position actually stayed open on Drift until 08:51 restart - * **6 hours unprotected** - no monitoring, no TP/SL backup, only orphaned on-chain orders - - **Why dangerous:** - * Database said "closed" so container restarts wouldn't restore monitoring - * Position exposed to unlimited risk if price moved against - * Only saved by luck (container restart at 08:51 detected orphaned position) - * Startup validator caught mismatch: "CRITICAL: marked as CLOSED in DB but still OPEN on Drift" - - **Impact:** Every trailing stop or SL exit vulnerable to this race condition - - **Fix (2-layer verification):** - ```typescript - // In lib/drift/orders.ts closePosition() (line ~634): - if (params.percentToClose === 100) { - console.log('🗑️ Position fully closed, cancelling remaining orders...') - await cancelAllOrders(params.symbol) - - // CRITICAL: Verify position actually closed on Drift - // Transaction confirmed ≠ Drift state updated immediately - console.log('⏳ Waiting 5s for Drift state to propagate...') - await new Promise(resolve => setTimeout(resolve, 5000)) - - const verifyPosition = await driftService.getPosition(marketConfig.driftMarketIndex) - if (verifyPosition && Math.abs(verifyPosition.size) >= 0.01) { - console.error(`🔴 CRITICAL: Close confirmed BUT position still exists!`) - console.error(` Transaction: ${txSig}, Drift size: ${verifyPosition.size}`) - // Return success but flag that monitoring should continue - return { - success: true, - transactionSignature: txSig, - closePrice: oraclePrice, - closedSize: sizeToClose, - realizedPnL, - needsVerification: true, // Flag for Position Manager - } - } - console.log('✅ Position verified closed on Drift') - } - - // In lib/trading/position-manager.ts executeExit() (line ~1206): - if ((result as any).needsVerification) { - console.log(`⚠️ Close confirmed but position still exists on Drift`) - console.log(` Keeping ${trade.symbol} in monitoring until Drift confirms closure`) - console.log(` Ghost detection will handle final cleanup once Drift updates`) - // Keep monitoring - don't mark closed yet - return - } - ``` - - **Behavior now:** - * Close transaction confirmed → wait 5 seconds - * Query Drift to verify position actually gone - * If still exists: Keep monitoring, log critical error, wait for ghost detection - * If verified closed: Proceed with database update and cleanup - * Ghost detection becomes safety net, not primary close mechanism - - **Prevents:** Premature database "closed" marking while position still open on Drift - - **TypeScript interface:** Added `needsVerification?: boolean` to ClosePositionResult interface - - **Git commits:** c607a66 (verification logic), b23dde0 (TypeScript interface fix) - - **Deployed:** Nov 16, 2025 09:28:20 CET - - **Verification Required:** - ```bash - # MANDATORY: Verify fixes are actually deployed before declaring working - docker logs trading-bot-v4 | grep "Server starting" | head -1 - # Expected: 2025-11-16T09:28:20 or later - - # Verify close verification logs on next trade close: - docker logs -f trading-bot-v4 | grep -E "(Waiting 5s for Drift|Position verified closed|needsVerification)" - - # Verify breakeven SL uses database entry: - docker logs -f trading-bot-v4 | grep "Breakeven SL: Using original entry price" - ``` - - **Lesson:** In DEX trading, always verify state changes actually propagated before updating local state. ALWAYS verify container restart timestamp matches or exceeds commit timestamps before declaring fixes deployed. - -48. **P&L compounding during close verification (CRITICAL - Fixed Nov 16, 2025):** - - **Symptom:** Database P&L shows $173.36 when actual P&L was $8.66 (20× too high) - - **Root Cause:** Variant of Common Pitfall #27 - duplicate external closure detection during close verification wait - - **Real incident (Nov 16, 11:50 CET):** - * SHORT position: Entry $141.64 → Exit $140.08 (expected P&L: $8.66) - * Close transaction confirmed, Drift verification pending (5-10s propagation delay) - * Position Manager returned with `needsVerification: true` flag - * **Every 2 seconds:** Monitoring loop checked Drift, saw position "missing", called `handleExternalClosure()` - * **Each call added P&L:** $112.96 → $117.62 → $122.28 → ... → $173.36 (14+ compounding updates) - * Rate limiting made it worse (429 errors delayed final cleanup) - - **Why it happened:** - * Fix #47 introduced `needsVerification` flag to keep monitoring during propagation delay - * BUT: No flag to prevent external closure detection during this wait period - * Monitoring loop thought position was "closed externally" every cycle - * Each detection calculated P&L and updated database, compounding the value - - **Impact:** Every close with verification delay (most closes) vulnerable to 10-20× P&L inflation - - **Fix (closingInProgress flag):** - ```typescript - // In ActiveTrade interface (line ~15): - // Close verification tracking (Nov 16, 2025) - closingInProgress?: boolean // True when close tx confirmed but Drift not yet propagated - closeConfirmedAt?: number // Timestamp when close was confirmed (for timeout) - - // In executeExit() when needsVerification returned (line ~1210): - if ((result as any).needsVerification) { - // CRITICAL: Mark as "closing in progress" to prevent duplicate external closure detection - trade.closingInProgress = true - trade.closeConfirmedAt = Date.now() - console.log(`🔒 Marked as closing in progress - external closure detection disabled`) - return - } - - // In monitoring loop BEFORE external closure check (line ~640): - if (trade.closingInProgress) { - const timeInClosing = Date.now() - (trade.closeConfirmedAt || Date.now()) - if (timeInClosing > 60000) { - // Stuck >60s (abnormal) - allow cleanup - trade.closingInProgress = false - } else { - // Normal: Skip external closure detection entirely during propagation wait - console.log(`🔒 Close in progress (${(timeInClosing / 1000).toFixed(0)}s) - skipping external closure check`) - } - } - - // External closure check only runs if NOT closingInProgress - if ((position === null || position.size === 0) && !trade.closingInProgress) { - // ... handle external closure - } - ``` - - **Behavior now:** - * Close confirmed → Set `closingInProgress = true` - * Monitoring continues but SKIPS external closure detection - * After 5-10s: Drift propagates, ghost detection cleans up correctly (one time only) - * If stuck >60s: Timeout allows cleanup (abnormal case) - - **Prevents:** Duplicate P&L updates during the 5-10s verification window - - **Related to:** Common Pitfall #27 (external closure duplicates), but different trigger - - **Files changed:** `lib/trading/position-manager.ts` (interface + logic) - - **Lesson:** When introducing wait periods in financial systems, always add flags to prevent duplicate state updates during the wait - -49. **P&L exponential compounding in external closure detection (CRITICAL - Fixed Nov 17, 2025):** - - **Symptom:** Database P&L shows 15-20× actual value (e.g., $92.46 when Drift shows $6.00) - - **Root Cause:** `trade.realizedPnL` was being mutated during each external closure detection cycle - - **Real incident (Nov 17, 13:54 CET):** - * SOL-PERP SHORT closed by on-chain orders: 1.54 SOL at -1.95% + 2.3 SOL at -0.57% - * Actual P&L from Drift: ~$6.00 profit - * Database recorded: $92.46 profit (15.4× too high) - * Rate limiting caused 15+ detection cycles before trade removal - * Each cycle compounded: $6 → $12 → $24 → $48 → $96 - - **Bug mechanism (line 799 in position-manager.ts):** - ```typescript - // BROKEN CODE: - const previouslyRealized = trade.realizedPnL // Gets from mutated in-memory object - const totalRealizedPnL = previouslyRealized + runnerRealized - trade.realizedPnL = totalRealizedPnL // ← BUG: Mutates in-memory trade object - - // Next monitoring cycle (2 seconds later): - const previouslyRealized = trade.realizedPnL // ← Gets ACCUMULATED value from previous cycle - const totalRealizedPnL = previouslyRealized + runnerRealized // ← Adds it AGAIN - trade.realizedPnL = totalRealizedPnL // ← Compounds further - // Repeats 15-20 times before activeTrades.delete() removes trade - ``` - - **Why Common Pitfall #48 didn't prevent this:** - * `closingInProgress` flag only applies when Position Manager initiates the close - * External closures (on-chain TP/SL orders) don't set this flag - * External closure detection runs in monitoring loop WITHOUT closingInProgress protection - * Rate limiting delays cause monitoring loop to detect closure multiple times - - **Fix:** - ```typescript - // CORRECT CODE (line 798): - const previouslyRealized = trade.realizedPnL // Get original value from DB - const totalRealizedPnL = previouslyRealized + runnerRealized - // DON'T mutate trade.realizedPnL here - causes compounding on re-detection! - // trade.realizedPnL = totalRealizedPnL ← REMOVED - console.log(` Realized P&L calculation → Previous: $${previouslyRealized.toFixed(2)} | Runner: $${runnerRealized.toFixed(2)} ... | Total: $${totalRealizedPnL.toFixed(2)}`) - - // Later in same function (line 850): - await updateTradeExit({ - realizedPnL: totalRealizedPnL, // Use local variable for DB update - // ... other fields - }) - ``` - - **Impact:** Every external closure (on-chain TP/SL fills) affected, especially with rate limiting - - **Database correction:** Manual UPDATE required for trades with inflated P&L - - **Verification:** Check that updateTradeExit uses `totalRealizedPnL` (local variable) not `trade.realizedPnL` (mutated field) - - **Why activeTrades.delete() before DB update didn't help:** - * That fix (Common Pitfall #27) prevents duplicates AFTER database update completes - * But external closure detection calculates P&L BEFORE calling activeTrades.delete() - * If rate limits delay the detection→delete cycle, monitoring loop runs detection multiple times - * Each time, it mutates trade.realizedPnL before checking if trade already removed - - **Git commit:** 6156c0f "critical: Fix P&L compounding bug in external closure detection" - - **Related bugs:** - * Common Pitfall #27: Duplicate external closure updates (fixed by delete before DB update) - * Common Pitfall #48: P&L compounding during close verification (fixed by closingInProgress flag) - * This bug (#49): P&L compounding in external closure detection (fixed by not mutating trade.realizedPnL) - - **Lesson:** In monitoring loops that run repeatedly, NEVER mutate shared state during calculation phases. Calculate locally, update shared state ONCE at the end. Immutability prevents compounding bugs in retry/race scenarios. - -50. **Database not tracking trades despite successful Drift executions (RESOLVED - Nov 19, 2025):** - - **Symptom:** Drift UI shows 6 trades executed in last 6 hours, database shows only 3 trades, P&L values inflated 5-14× - - **Root Cause:** P&L compounding bug in external closure detection - `trade.realizedPnL` reading from in-memory object with stale/accumulated values - - **Evidence:** - * Database showed: $581, $273, -$434 P&L for 3 trades (total $420 profit) - * Actual P&L: $59.35, $19.79, -$87.88 (total -$8.74 loss) - * Inflation: 9.8×, 13.8×, 5× respectively - * Missing trades: ~3 trades from pre-06:51 container restart not in database - - **Bug Mechanism:** - 1. External closure detected, calculates: `totalRealizedPnL = previouslyRealized + runnerRealized` - 2. `previouslyRealized` reads from in-memory `trade.realizedPnL` (could be stale) - 3. Updates database with compounded value - 4. If detected again (race condition/rate limits), reads ALREADY ACCUMULATED value - 5. Adds more P&L, compounds 2×, 5×, 10× - - **Fix Applied (Nov 19, 2025):** - * Removed `previouslyRealized` from external closure P&L calculation - * Now calculates ONLY current closure's P&L: `totalRealizedPnL = runnerRealized` - * Database corrected via SQL UPDATE: recalculated P&L from entry/exit prices - * Formula: `positionSizeUSD × ((exitPrice - entryPrice) / entryPrice)` for longs - * Code: lib/trading/position-manager.ts lines 785-803 - - **Verification (08:40 CET):** - * New v8 trade executed successfully - * n8n workflow functioning (22.49s execution) - * Database save working correctly - * Analytics now shows accurate -$8.74 baseline - - **Current Status:** - * System fully operational - * Analytics baseline: 3 trades, -$8.74 P&L, 66.7% WR - * Historical gap: ~3 pre-restart trades not in DB (explains -$52 Drift vs -$8.74 DB) - * All future trades will track accurately - - **Lesson:** In-memory state can accumulate stale values across detection cycles. For financial calculations, always use fresh data or calculate from immutable source values (entry/exit prices), never from potentially mutated in-memory fields. - -51. **TP1 detection fails when on-chain orders fill fast (CRITICAL - Fixed Nov 19, 2025):** - - **Symptom:** TP1 order fills on-chain (75% of position), but database records exitReason as "SL" instead of "TP1" - - **Root Cause:** Position Manager monitoring loop detects closure AFTER both TP1 and runner already closed on-chain, can't determine TP1 triggered first - - **Real incident (Nov 19, 07:40 UTC / 08:40 CET):** - * LONG opened: $140.1735 entry, $7788 position - * TP1 order placed: $140.8743 for 75% of position - * TP1 filled on-chain within seconds - * Runner (25%) also closed within 7 minutes - * Position Manager detected external closure with entire position gone - * `trade.tp1Hit = false` (never updated when TP1 filled) - * Treated as full position SL close instead of TP1 + runner - * Database: exitReason="SL", but actual profit $37.67 (0.48%, clearly TP1 range!) - - **Why it happens:** - * On-chain limit orders fill independently of Position Manager monitoring - * TP1 fills in <1 second when price crosses - * Runner closes via SL or trailing stop (also fast) - * Position Manager monitoring loop runs every 2 seconds - * By time PM checks, entire position gone - can't tell TP1 filled first - * tp1Hit flag only updates when PM directly closes position, not for external fills - - **Impact:** - * Analytics shows wrong exit reason distribution (too many "SL", missing "TP1" wins) - * Can't accurately assess TP1 effectiveness - * Profit attribution incorrect (winners marked as losers) - - **Fix Attempts:** - 1. Query Drift order history - FAILED (SDK doesn't expose simple API) - 2. Infer from P&L magnitude ratio - FAILED (too complex, unreliable) - 3. Simple percentage-based thresholds - DEPLOYED ✅ - - **Final Fix (Nov 19, 08:08 UTC):** - ```typescript - // In lib/trading/position-manager.ts lines 760-835 - - // Always use full position for P&L calculation - const sizeForPnL = trade.originalPositionSize - - // Calculate profit percentage - const runnerProfitPercent = this.calculateProfitPercent( - trade.entryPrice, - currentPrice, - trade.direction - ) - - // Simple percentage-based exit reason - let exitReason: string - if (runnerProfitPercent > 0.3) { - if (runnerProfitPercent >= 1.2) { - exitReason = 'TP2' // Large profit (>1.2%) - } else { - exitReason = 'TP1' // Moderate profit (0.3-1.2%) - } - } else { - exitReason = 'SL' // Negative or tiny profit (<0.3%) - } - ``` - - **Threshold Rationale:** - * TP1 typically placed at ~0.86% (ATR × 2.0) - * Profit 0.3-1.2% strongly indicates TP1 filled - * Profit >1.2% indicates TP2 range - * Profit <0.3% is SL/breakeven territory - - **Removed Logic:** - * Complex tp1Hit flag inference - * Drift order history querying (doesn't exist) - * P&L ratio calculations (unreliable) - - **Benefits:** - * Simple, reliable, based on actual results - * Works regardless of how position closed - * No dependency on Drift SDK order APIs - * More accurate than state flag tracking for external fills - - **Verification Required:** - * Next trade that hits TP1 should show exitReason="TP1" - * Profit in 0.3-1.2% range should categorize correctly - * Analytics exit reason distribution should match reality - - **Git commit:** de57c96 "fix: Correct TP1 detection for on-chain order fills" - - **Lesson:** When orders fill externally (on-chain), state flags (tp1Hit) unreliable. Infer exit reason from results (profit percentage) rather than process tracking. Simple logic often more reliable than complex state machines for fast-moving on-chain events. - -52. **ADX-based runner SL only applied in one code path (CRITICAL - Fixed Nov 19, 2025):** - - **Symptom:** TP1 fills via on-chain order, runner gets breakeven SL instead of ADX-based positioning - - **Root Cause:** Two separate TP1 detection paths in Position Manager: - 1. **Direct price check** (lines 1050-1100) - Has ADX-based runner SL ✅ - 2. **On-chain fill detection** (lines 590-650) - Hard-coded breakeven ❌ - - **Real incident (Nov 19, 12:40 CET):** - * SHORT opened: $138.3550, ADX 20.0 - * TP1 filled via on-chain order (60% closed) - * Expected: ADX 20.0 (moderate tier) → runner SL at -0.3% ($138.77) - * Actual: Hard-coded breakeven SL ($138.355) - * Bug: On-chain fill detection bypassed ADX logic completely - - **Why two paths exist:** - * Direct price check: Position Manager detects TP1 price crossed - * On-chain fill: Detects size reduction from order fill (most common) - * Both paths mark `tp1Hit = true` but only direct path had ADX logic - - **Impact:** Most TP1 triggers happen via on-chain orders, so ADX system not working for majority of trades - - **Fix (Nov 19, 13:50 CET):** - ```typescript - // In lib/trading/position-manager.ts lines 607-642 - // On-chain fill detection path - - // ADX-based runner SL positioning (Nov 19, 2025) - // Strong trends get more room, weak trends protect capital - let runnerSlPercent: number - const adx = trade.adxAtEntry || 0 - - if (adx < 20) { - runnerSlPercent = 0 // Weak trend: breakeven - console.log(`🔒 ADX-based runner SL: ${adx.toFixed(1)} → 0% (breakeven - weak trend)`) - } else if (adx < 25) { - runnerSlPercent = -0.3 // Moderate trend - console.log(`🔒 ADX-based runner SL: ${adx.toFixed(1)} → -0.3% (moderate trend)`) - } else { - runnerSlPercent = -0.55 // Strong trend - console.log(`🔒 ADX-based runner SL: ${adx.toFixed(1)} → -0.55% (strong trend)`) - } - - const newStopLossPrice = this.calculatePrice( - trade.entryPrice, - runnerSlPercent, - trade.direction - ) - trade.stopLossPrice = newStopLossPrice - ``` - - **Commits:** - * b2cb6a3 "critical: Fix ADX-based runner SL in on-chain fill detection path" - * 66b2922 "feat: ADX-based runner SL positioning" (original implementation) - - **Verification:** Next TP1 hit via on-chain order will show ADX-based log message - - **Lesson:** When implementing adaptive logic, check ALL code paths that reach that decision point.

- **Why Drift UI works:** Has internal safety calculations that bot must replicate externally - - **Math proof:** 1% buffer on $85 = $0.85 safety margin (covers typical fees of $0.03-0.10) - - **Git commit:** 7129cbf "fix: Add 99% safety buffer for 100% position sizing" -

Fixed Nov 16, 2025):** - - **Symptom:** Close transaction confirmed on-chain, database marked "SL closed", but position stayed open on Drift for 6+ hours unmonitored - - **Root Cause:** Transaction confirmation ≠ Drift internal state updated immediately (5-10 second propagation delay) - - **Real incident (Nov 16, 02:51 CET):** - * Trailing stop triggered at 02:51:57 - * Close transaction confirmed on-chain ✅ - * Position Manager immediately queried Drift → still showed open (stale state) - * Ghost detection eventually marked it "closed" in database - * But position actually stayed open on Drift until 08:51 restart - * **6 hours unprotected** - no monitoring, no TP/SL backup, only orphaned on-chain orders - - **Why dangerous:** - * Database said "closed" so container restarts wouldn't restore monitoring - * Position exposed to unlimited risk if price moved against - * Only saved by luck (container restart at 08:51 detected orphaned position) - * Startup validator caught mismatch: "CRITICAL: marked as CLOSED in DB but still OPEN on Drift" - - **Impact:** Every trailing stop or SL exit vulnerable to this race condition - - **Fix (2-layer verification):** - ```typescript - // In lib/drift/orders.ts closePosition() (line ~634): - if (params.percentToClose === 100) { - console.log('🗑️ Position fully closed, cancelling remaining orders...') - await cancelAllOrders(params.symbol) -

// Keep monitoring - don't mark closed yet - return - } - ``` - - **Behavior now:** - * Close transaction confirmed → wait 5 seconds - * Query Drift to verify position actually gone - * If still exists: Keep monitoring, log critical error, wait for ghost detection - * If verified closed: Proceed with database update and cleanup - * Ghost detection becomes safety net, not primary close mechanism - - **Prevents:** Premature database "closed" marking while position still open on Drift - - **Git commit:** c607a66 "critical: Fix position close verification to prevent ghost positions" - - **Lesson:** In DEX trading, always verify state changes actually propagated before updating local state -

Runner tries to close via `executeExit()` → 429 rate limit error - 2. Trade stays in monitoring, `priceCheckCount` increments every 2s - 3. After 20+ failures: Layer 2 checks Drift API, finds position gone - 4. Calls `handleExternalClosure()` immediately without checking `closingInProgress` - 5. Async database update still in progress from previous call - 6. Next monitoring cycle (2s later): priceCheckCount still > 20, Drift still shows gone - 7.

First iteration detects size reduction, calls `handleManualClosure` - 3. `handleManualClosure` removes trade via `activeTrades.delete(trade.id)` - 4. But loop continues with original array that still contains removed trade - 5. Second iteration processes same trade object (stale reference) - 6. No check if trade still in monitoring → duplicate processing - - **Impact:** Every manual closure vulnerable to duplicate notifications if multiple trades in monitoring loop - - **Fix (lib/trading/position-manager.ts line 545):** - ```typescript - private async checkTradeConditions( - trade: ActiveTrade, - currentPrice: number - ): Promise { - // CRITICAL FIX (Nov 23, 2025): Check if trade still in monitoring - if (!this.activeTrades.has(trade.id)) { - console.log(`⏭️ Skipping ${trade.symbol} - already removed from monitoring`) - return - } - - // Continue with normal processing... - trade.lastPrice = currentPrice - trade.lastUpdateTime = Date.now() - trade.priceCheckCount++ - // ... rest of function - } - ``` - - **Behavior now:** - * First iteration: Processes trade, removes from map - * Second iteration: Guard checks map, trade not found, returns immediately - * Prevents duplicate database updates and Telegram notifications - - **Why Common Pitfall #59 didn't cover this:** - * Pitfall #59: Layer 2 ghost detection (failureCount > 20) during rate limit storms - * This bug (#60): Normal monitoring loop during manual closures - * Different code paths, different triggers, same pattern needed everywhere - - **Configuration discrepancy discovered same session:** - * User reported Trade #9 (quality 90, -$22.41) should've been blocked - * `.env` had `MIN_SIGNAL_QUALITY_SCORE=81` (outdated) - * Code raised threshold to 91 on Nov 21, but `.env` not updated - * Fixed: `sed -i 's/MIN_SIGNAL_QUALITY_SCORE=81/91/' .env` - * Container restart required for settings changes to propagate - - **Settings UI enhancement:** - * Added console warning: "⚠️ Container restart recommended" - * Changed comment from "immediate effect" to "temporary, may not persist" - * Future: Need auto-restart trigger or UI notification - - **Files changed:** - * `lib/trading/position-manager.ts` (guard added) - * `app/api/settings/route.ts` (restart warning added) - - **Git commit:** a7c5930 "critical: Fix duplicate Telegram notifications + settings UI restart requirement" - - **Deployed:** Nov 23, container rebuilt (71.8s), all services running - - **Lesson:** When async processing modifies collections during iteration, always guard against stale references. Array snapshots don't protect against this - need explicit membership checks. ALL monitoring code paths need duplicate prevention, not just error scenarios. - -62. **Execute endpoint bypassing quality threshold validation (CRITICAL - Fixed Nov 27, 2025):** - - **Symptom:** Bot executed trades at quality 30, 50, 50 when minimum threshold is 90 (LONG) / 95 (SHORT) - - **Root Cause:** Execute endpoint calculated quality score but never validated it after timeframe='5' confirmation - - **Real incidents (Nov 27, 2025):** - * Trade cmihwkjmb0088m407lqd8mmbb: Quality 30, entry $142.63, 20:45:23, exit SOFT_SL - * Trade cmih6ghn20002ql07zxfvna1l: Quality 50, entry $142.31, 08:34:24, exit SL - * Trade cmih5vrpu0001ql076mj3nm63: Quality 50, entry $142.92, 08:18:17, exit SL - * **All three stopped out** - confirms low quality = losing trades - - **TradingView sent incomplete data:** - ``` - Risk check for: { - timeframe: '5', - atr: 0, - adx: 0, - rsi: 0, - volumeRatio: 0, - pricePosition: 0, - indicatorVersion: 'v5' // Old indicator, not current v9 - } - ``` - * All metrics = 0 → Quality calculated as 30 - * Old indicator v5 still firing (should be v9) - - **Bug sequence:** - 1.

Verify with test trade after deployment, not just code review. - -63. **Smart Entry Validation System - Block & Watch (DEPLOYED - Nov 30, 2025):** - - **Purpose:** Recover profits from marginal quality signals (50-89) that would otherwise be blocked - - **Strategy:** Queue blocked signals, monitor 1-minute price action for 10 minutes, enter if price confirms direction - - **Implementation:** `lib/trading/smart-validation-queue.ts` (330+ lines) - - **Threshold Optimization (Dec 1, 2025):** - * **Backtest:** 200 random DATA_COLLECTION_ONLY signals (Nov 19-30, 2025) - * **Results:** - - **CURRENT (±0.3%):** 28/200 entries (14%), 67.9% WR, +4.73% total, **+0.169% avg** ✅ - - OPTION 1 (±0.2%): 51/200 entries (26%), 43.1% WR, -18.49% total, -0.363% avg - - OPTION 2 (±0.15%): 73/200 entries (36%), 35.6% WR, -38.27% total, -0.524% avg - * **Finding:** Lower thresholds catch significantly more losers than winners - - 0.3% → 0.2%: 23 more entries, 3 more winners, 20 MORE LOSERS (-23.22% P&L degradation) - - 0.2% → 0.15%: 22 more entries, 4 more winners, 18 MORE LOSERS (-19.78% P&L degradation) - - Pattern: Lower threshold = higher entry rate but WR collapses (68% → 43% → 36%) - * **Statistical validation:** n=200 sample confirms initial n=11 finding held true at scale - * **Decision:** Keep current ±0.3% thresholds (optimal risk/reward balance) - - **Core Logic:** - * **Queue:** Signals with quality 50-89 (below 50 = hard block, 90+ = immediate execution) - * **Monitor:** Check price every 30 seconds using market data cache - * **Confirm:** LONG at +0.3% move, SHORT at -0.3% move → auto-execute via /api/trading/execute - * **Abandon:** LONG at -0.4% drawdown, SHORT at +0.4% rise → saved from potential loser - * **Expire:** After 10 minutes if no confirmation → signal ignored - * **Notifications:** Telegram messages for queued/confirmed/abandoned/expired/executed events - - **Integration Points:** - * check-risk endpoint: Calls `validationQueue.addSignal()` when quality score too low - * **CRITICAL:** Only applies to 5-minute trading signals (timeframe='5') - * **DOES NOT apply to 1-minute data collection** (timeframe='1' bypasses check-risk entirely) - * Startup: `lib/startup/index.ts` calls `startSmartValidation()` - * Market data: Uses `getMarketDataCache()` for real-time 1-minute prices - - **Example Flow:** - ``` - T+0: LONG signal at $137.545, quality 50 - ❌ Blocked from immediate execution - ✅ Queued for validation - 📱 Telegram: "⏰ SOL-PERP LONG blocked (quality 50) - monitoring for 10min" - - T+3min: Price $138.10 (+0.41%) - CONFIRMATION HIT! - ✅ Validates at +0.41% (exceeds +0.3% threshold) - 📱 Telegram: "✅ SOL-PERP LONG VALIDATED - Price moved +0.41%" - 🚀 Auto-executes trade at $138.10 - 📱 Telegram: "🚀 Validated trade EXECUTED - Trade ID: cm..." - - Result: $138.10 → $140.01 = +1.38% profit - (vs blocked: $0 profit, vs full move: +1.79% = 77% capture rate) - ``` - - **Expected Impact:** - * Recover ~30% of blocked winners (+15 trades/month) - * Still filter ~70% of true losers via abandonment - * Estimated monthly recovery: +$1,823 profit - * Entry slippage: +0.3% from signal price (acceptable for 77% move capture) - - **Database Fields:** Trade table includes `validatedEntry: true`, `originalQualityScore`, `validationDelayMinutes` for analytics - - **Monitoring Commands:** - ```bash - # Watch validation events - docker logs -f trading-bot-v4 | grep -E "(Smart validation|VALIDATED|ABANDONED|EXPIRED)" - - # Check queue status - curl http://localhost:3001/api/trading/smart-validation-status - ``` - - **Safety Design:** - * Auto-start monitoring when first signal queued - * Auto-stop when queue empty (save resources) - * 30-second check interval (balance responsiveness vs overhead) - * Uses existing 1-minute data infrastructure (no new alerts needed) - * Confirmation threshold high enough to filter noise (+0.3% = ~$0.40 on $137 SOL) - * Abandonment threshold protects from reversals (-0.4% = ~$0.55 drawdown max) - - **Commit:** 7c9cfba "feat: Add Smart Entry Validation Queue system - Block & Watch for quality 50-89 signals" - - **Files:** - * `lib/trading/smart-validation-queue.ts` - Main queue implementation - * `lib/notifications/telegram.ts` - sendValidationNotification() function - * `app/api/trading/check-risk/route.ts` - Integration point (calls addSignal()) - - **Lesson:** When building validation systems, use existing infrastructure (1-min data cache) instead of creating new dependencies. Confirmation via price action is more reliable than pre-filtering with strict thresholds. Balance between catching winners (0.3% confirms) and avoiding losers (0.4% abandons) requires tuning based on 50-100 validation outcomes. - -64. **EPYC Cluster SSH Timeout - Nested Hop Requires Longer Timeouts (CRITICAL - Fixed Dec 1, 2025):** - - **Symptom:** Coordinator reports "operation failed" with "SSH command timed out for v9_chunk_000002 on worker1" - - **Root Cause:** 30-second subprocess timeout insufficient for nested SSH hop (master → worker1 → worker2) - - **Real incident (Dec 1, 2025):** - * EPYC cluster with 2 servers (64 cores total) failed to start workers - * Worker1 (direct SSH): Reachable instantly - * Worker2 (via SSH hop through worker1): Required 40+ seconds to start processes - * Coordinator timeout set to 30s → worker2 startup always failed - * Database showed chunks as "running" but no actual processes existed - - **Impact:** Distributed parameter exploration completely non-functional, 64 cores sitting idle - - **Three-part fix (cluster/distributed_coordinator.py):** - ```python - # 1. Added SSH options for reliability (lines 302-318) - ssh_opts = "-o StrictHostKeyChecking=no -o ConnectTimeout=10 -o ServerAliveInterval=5" - - # 2. Increased subprocess timeout (lines 396-418) - result = subprocess.run( - ssh_cmd, - shell=True, - capture_output=True, - text=True, - timeout=60 # Increased from 30s to 60s - ) - - # 3. Enhanced error messages - except subprocess.TimeoutExpired: - print(f"⚠️ SSH command timed out for {chunk_id} on {worker_name}") - print(f" This usually means SSH hop is misconfigured or slow") - ``` - - **SSH Options Added:** - * `-o StrictHostKeyChecking=no` → Prevents password prompts on first connection - * `-o ConnectTimeout=10` → Fails fast if host unreachable (don't wait indefinitely) - * `-o ServerAliveInterval=5` → Prevents silent connection drops during long operations - - **Verification (Dec 1, 2025):** - * Worker1: 23 Python processes at 99% CPU processing chunk 0 (0-2000 combos) - * Worker2: 24 Python processes at 99% CPU processing chunk 1 (2000-4000 combos) - * Both workers loading 34,273 rows of SOL/USDT 5-minute data - * Database correctly showing 2 chunks "running", 1 chunk "pending" - * Coordinator running in background, monitoring every 60 seconds - - **Files changed:** `cluster/distributed_coordinator.py` (13 insertions, 5 deletions) - - **Commit:** ef371a1 "fix: EPYC cluster SSH timeout - increase timeout 30s→60s + add SSH options" - - **Why 60 seconds:** Nested SSH hop has compounding latency: - * Master → Worker1 connection: ~2-3 seconds - * Worker1 → Worker2 connection: ~2-3 seconds via hop - * Start Python process with multiprocessing: ~10-15 seconds - * Load 34K rows of data: ~5-10 seconds - * Initialize 22-24 worker processes: ~10-20 seconds - * Total: 30-50 seconds typical, 60s provides safety margin - - **Lessons Learned:** - 1. **Nested SSH hops need 2× minimum timeout** - Latency compounds at each hop - 2. **Always use StrictHostKeyChecking=no for automation** - Prevents interactive prompts - 3. **ServerAliveInterval prevents silent hangs** - Especially important for long-running processes - 4. **Database cleanup essential before retries** - Stale "running" chunks prevent new assignments - 5. **Verify actual process existence, not just database status** - Database can lie if previous run failed - 6. **Test SSH connectivity separately before distributed execution** - Catch auth issues early - - **Future Prevention:** - * Document minimum timeout formula: `base_timeout = (num_hops × 5s) + (process_startup × 2) + safety_margin(10s)` - * For 2 hops with heavy startup: `(2 × 5) + (20 × 2) + 10 = 60 seconds` - * Monitor coordinator logs for timeout patterns, increase if needed - * Consider SSH multiplexing (ControlMaster) to speed up nested hops - -65. **Distributed Worker Quality Filter - Dict vs Callable (CRITICAL - Fixed Dec 1, 2025):** - - **Symptom:** ALL 2,096 distributed backtests returned 0 trades (expected 500-600 each) - - **Error Message:** `Error testing config X: 'dict' object is not callable` repeated 2,096 times in worker logs - - **Root Cause:** `cluster/distributed_worker.py` lines 67-70 passed dict `{'min_adx': 15, 'min_volume_ratio': vol_min}` instead of lambda function to `simulate_money_line()` - - **Technical Detail:** `backtester/simulator.py:118` calls `quality_filter(signal)` - expects CALLABLE function, not dict configuration - - **Silent Failure Pattern:** Worker's try/except caught exception and returned default values (0 trades, 0 P&L) without crashing - - **Discovery:** Found only when analyzing result content - CSVs looked valid but all trades=0 - - **Fix (Commit 11a0ea3):** - ```python - # BEFORE (BROKEN): - quality_filter = {'min_adx': 15, 'min_volume_ratio': vol_min} - - # AFTER (FIXED): - if vol_min > 0: - quality_filter = lambda s: s.adx >= 15 and s.volume_ratio >= vol_min - else: - quality_filter = None - ``` - - **Pattern Source:** Matches working `comprehensive_sweep.py:106` implementation - - **Why It Broke:** Developer treated quality_filter as configuration dict, but it's actually a callback function called on every signal - - **Verification:** Workers at 100% CPU, no errors after 2+ minutes, actively computing valid backtests - - **Lessons Learned:** - 1. **Type mismatches (dict vs callable) can cause catastrophic silent failures** - Python's dynamic typing hides the error until runtime - 2. **Always validate result quality** - All zeros = red flag requiring immediate investigation - 3. **Compare to working code when debugging** - comprehensive_sweep.py had correct pattern - 4. **Silent failures more dangerous than crashes** - Exception handler hid severity by returning zeros instead of crashing - 5. **Test single case before running full sweep** - Would have caught error in 30 seconds vs 22 minutes - 6. **Add result assertions** - System should detect all-zero results and abort early - - **Documentation:** `cluster/CRITICAL_BUG_FIX_DEC1_2025.md` - - **Impact:** Blocked 45 minutes of distributed work, wasted cluster compute, caught before Stage 1 analysis - - **Files changed:** `cluster/distributed_worker.py` lines 67-77 - -66. **Smart Entry Validation Queue wrong price display (CRITICAL - Fixed Dec 1, 2025):** - - **Symptom:** Abandonment notifications in Telegram showing incorrect/impossible prices (e.g., $126.00 → $98.18 = -22.08% drop in 30 seconds) - - **User Report:** "the abandonend signal shows the wrong price. it never went that low" - -67. **Ghost detection race condition causing duplicate notifications with P&L compounding (CRITICAL - Fixed Dec 2, 2025):** - - **Symptom:** 23 duplicate Telegram "POSITION CLOSED" notifications for single manual SHORT trade with P&L compounding from -$47.96 to -$1,129.24 - - **Real incident (Dec 2, 17:20 CET):** - * Manual SHORT opened: Entry $138.84, exit ~$140.20 - * Expected P&L: ~-$48 (single close) - * Actual: 23 identical notifications with compounding P&L (-$47.96 → -$102.25 → -$253.40 → ... → -$1,129.24) - * Database: Single trade record with final compounded P&L (-$1,129.24) - * Hold time: Consistent 27-29 minutes across all notifications - * Exit reason: "Ghost detected during monitoring" then "SL" - - **Root Cause:** Race condition in ghost detection cleanup handler - ```typescript - // BUGGY CODE (OLD): - async handleExternalClosure(trade: ActiveTrade, reason: string) { - const tradeId = trade.id - - // ❌ Check happens here - AFTER function entry - if (!this.activeTrades.has(tradeId)) { - console.log('DUPLICATE PREVENTED') - return - } - - // Async operations... - const estimatedPnL = calculatePnL() // Takes time - - // Delete happens late - this.activeTrades.delete(tradeId) // ❌ TOO LATE - - // Multiple loops reach here - await updateTradeExit({realizedPnL: estimatedPnL}) // P&L compounds - await sendTelegram() // Duplicate notification -

``` - - **Fix:** Use Map.delete() atomic return value as deduplication lock - ```typescript - // FIXED CODE (NEW): - async handleExternalClosure(trade: ActiveTrade, reason: string) { - const tradeId = trade.id - - // ✅ Delete IMMEDIATELY - atomic operation - // Map.delete() returns true if deleted, false if key didn't exist - if (!this.activeTrades.delete(tradeId)) { - console.log('DUPLICATE PREVENTED (atomic lock)') -

* **Atomic:** Single operation, no race condition possible - * **Boolean return:** true if key existed and was deleted, false if key didn't exist - * **Perfect lock:** First caller gets true, subsequent callers get false - * **No async gap:** Deletion happens before any await statements - - **Impact:** Every ghost detection event vulnerable to duplicate notifications if multiple monitoring loops detected same ghost - - **Files changed:** `lib/trading/position-manager.ts` lines 380-430 (handleExternalClosure method) - - **Git commit:** 93dd950 "critical: Fix ghost detection P&L compounding - delete from Map BEFORE check" - - **Deployed:** Dec 2, 2025 17:32:52 UTC - - **Related:** Common Pitfalls #48-49 (TP1 P&L compound), #59-61 (external closure duplicates) - - **Lesson:** When async handler can be called by multiple code paths simultaneously, use atomic operations (like Map.delete()) as locks at function entry, NOT checks (like Map.has()) that can race - - **Root Cause:** Symbol format mismatch between validation queue storage and market data cache lookup - * TradingView webhook sends: `"SOLUSDT"`, `"ETHUSDT"`, etc. - * check-risk endpoint passed: `body.symbol` directly to validation queue without normalization - * Validation queue stored: `signal.symbol = "SOLUSDT"` - * Market data cache uses: Normalized Drift format `"SOL-PERP"`, `"ETH-PERP"` - * Cache lookup: `marketDataCache.get("SOLUSDT")` returns `null` (key not found) - * Result: No cached data, wrong/stale price used in Telegram abandonment notification - - **Real Incident (Dec 1, 2025):** - * Signal queued at $126.00 - * Abandonment notification showed $98.18 - * Reported drop: -22.08% in 30 seconds (physically impossible for SOL) - * Actual: Cache lookup failed due to symbol format, displayed stale/wrong price - - **Impact:** Every Smart Entry Validation Queue abandonment notification shows incorrect price, misleading user about system behavior and market conditions - - **Data Flow Before Fix:** - 1. TradingView → check-risk: `{"symbol": "SOLUSDT", ...}` - 2. check-risk → validation queue: `symbol: "SOLUSDT"` (no normalization) - 3. Validation queue stores: `signal.symbol = "SOLUSDT"` - 4. Validation loop: `marketDataCache.get("SOLUSDT")` → **null** (key mismatch) - 5. Telegram notification: Shows wrong/stale price - - **Data Flow After Fix:** - 1. TradingView → check-risk: `{"symbol": "SOLUSDT", ...}` - 2. check-risk normalizes: `const normalizedSymbol = normalizeTradingViewSymbol("SOLUSDT")` → `"SOL-PERP"` - 3. check-risk → validation queue: `symbol: "SOL-PERP"` (normalized) - 4. Validation loop: `marketDataCache.get("SOL-PERP")` → **success** (key matches) - 5. Telegram notification: Shows correct current price from cache - - **Fix (app/api/trading/check-risk/route.ts):** - ```typescript - // Line 9: Added import - import { normalizeTradingViewSymbol } from '@/config/trading' - - // Lines 432-444: Normalize symbol before validation queue - // CRITICAL FIX (Dec 1, 2025): Normalize TradingView symbol format to Drift format - // Bug: Market data cache uses "SOL-PERP" but TradingView sends "SOLUSDT" -

- const queued = await validationQueue.addSignal({ - blockReason: 'QUALITY_SCORE_TOO_LOW', - symbol: normalizedSymbol, // Use normalized format for cache lookup - direction: body.direction, - originalPrice: currentPrice, - qualityScore: qualityScore.score, - // ... other parameters - }) - - // Line 458: Updated console.log - console.log(`🧠 Signal queued for smart validation: ${normalizedSymbol} ${body.direction}...`) - ``` - - **Files Changed:** - * `app/api/trading/check-risk/route.ts` (line 9 import, lines 432-444 normalization, line 458 log) - * Total: 6 insertions including comment block - - **Related Components (No Changes Needed):** - * `lib/trading/smart-validation-queue.ts` - Receives normalized symbol, validation logic correct - * `lib/trading/market-data-cache.ts` - Uses normalized format "SOL-PERP" (line 11 comment) - * `lib/notifications/telegram.ts` - Displays whatever price passed, formatter correct - * `app/api/trading/market-data/route.ts` - Already normalizes correctly (reference implementation) - * `config/trading.ts` - Contains `normalizeTradingViewSymbol()` function at line 238 - - **Git Commit:** 6cec2e8 "critical: Fix Smart Entry Validation Queue wrong price display" - - **Deployed:** Dec 1, 2025, 23:45:21 +0100 (container trading-bot-v4 restarted with fix) - - **Verification Required:** - * Wait for next marginal quality signal (quality 50-89) to be queued - * Monitor validation queue logs: Should show normalized symbol format ("SOL-PERP" not "SOLUSDT") - * Check Telegram abandonment: Should show correct price matching market reality - * Verify cache lookup succeeds: Console logs "✅ Using fresh TradingView data for SOL-PERP" - - **Lessons Learned:** - 1. **Symbol format consistency is CRITICAL across all system components** - One endpoint without normalization breaks entire data flow - 2. **Cache key mismatches fail silently** - `marketDataCache.get("WRONG-KEY")` returns `null`, no error thrown - 3. **Always normalize at integration boundaries** - External webhooks (TradingView) → Internal systems (validation queue, cache) require format conversion - 4. **Market data cache uses Drift format as standard** - "SOL-PERP", "ETH-PERP", "BTC-PERP" (not TradingView "SOLUSDT", "ETHUSDT") - 5. **ALL endpoints feeding validation queue must normalize** - check-risk, execute, market-data all need consistent symbol handling - 6. **Verify data flow end-to-end** - Trace from webhook → storage → lookup → display to catch format mismatches - 7. **Silent failures cause data corruption downstream** - Wrong price displayed misleads user about system behavior - - **Why This Matters:** - * Smart Entry Validation Queue is profit recovery system for marginal quality signals (expected +$1,823/month) - * Wrong abandonment prices mislead user about system decisions (appears system abandoned profitable setups) - * In real money trading, user relies on accurate notifications for manual intervention decisions - * Cache lookups are critical path for all validation queue price checks (every 30 seconds) - -68. **Smart Entry using webhook percentage as signal price (CRITICAL - Fixed Dec 3, 2025):** - - **Symptom:** $89 position sizes, 97% pullback calculations, impossible entry conditions preventing ALL Smart Entry trades - - **User Report:** "why is position size so tiny?" → $89 instead of expected $2,300 - - **Real Incident (Dec 3, 2025, 07:16-09:02 CET):** - * SOL-PERP LONG signal: Quality 92, market price $142.50 - * Expected: $2,300 position at 10x leverage - * Actual: $89 position blocked due to impossible Smart Entry condition - * Smart Entry log: "97.4% pullback required" (impossible to trigger) - - **Root Cause:** TradingView webhook `signal.price` field contained percentage value (70.80) instead of market price ($142.50) - ```typescript - // BUGGY CODE (OLD): - const signalPrice = signal.price // ❌ 70.80 (percentage from TradingView) - const currentPrice = 142.50 // Current SOL price - const pullbackPercent = ((currentPrice - signalPrice) / signalPrice) * 100 - // = ((142.50 - 70.80) / 70.80) * 100 = 101.2% pullback - // Smart Entry requires: actualPullback > pullbackPercent (impossible!) - ``` - - **Investigation Timeline:** - * 07:16 CET: Signal received, position opened with $89 size - * User noticed: "why so tiny?" - * Agent investigated: Position sizing code correct, leverage correct - * Discovery: Smart Entry calculating 97% pullback from wrong signal price - * Root cause: signal.price = 70.80 (TradingView percentage) not $142.50 (market price) - - **Fix:** Use Pyth current price instead of webhook signal price - ```typescript - // FIXED CODE (NEW): - // Get current price from Pyth (reliable market data) - const pythPrice = await pythClient.getPrice(symbol) - const signalPrice = pythPrice.price // ✅ Use actual market price, not webhook - - // Now pullback calculation makes sense: - // If price pulls back from $142.50 to $141.50 = 0.7% pullback (reasonable) - ``` - - **Files Modified:** - * `app/api/trading/execute/route.ts` - Smart Entry signal price source (lines ~680-700) - * Used Pyth price (already fetched for position sizing) instead of webhook price - - **Git Commit:** 7d0d38a "Fix Bug #1: Smart Entry uses wrong signal price (webhook percentage)" - - **Deployed:** Dec 3, 2025, 09:02:45 CET (container trading-bot-v4 restarted, timestamp verified: 09:02:45 > 08:16:27 ✅) - - **Verification Required:** - * Wait for next quality 90+ signal with Smart Entry conditions - * Expected: Signal price ~$140-145 (market price, not ~$80 percentage) - * Expected: Position size ~$2,300 (not $89) - * Expected: Pullback calculation <1% (not 97%) - - **Lessons Learned:** - 1. **Never trust webhook data for calculations** - Use authoritative price sources (Pyth, Drift) - 2. **TradingView alert payloads contain mixed data types** - Price fields may contain percentages, scores, or actual prices depending on alert configuration - 3. **Sanity check calculations** - 97% pullback requirement is impossible, should have caught this - 4. **Position sizing worked perfectly** - Bug was ONLY in Smart Entry, not position size logic - 5. **Investigate user complaints thoroughly** - "$89 position" led to discovering Smart Entry bug, not position sizing bug - 6. **Use already-fetched data** - Pyth price was already retrieved for position sizing, reuse for Smart Entry - - **Why This Matters:** - * Smart Entry is profit optimization feature (waits for better entry prices) - * Using wrong signal price made Smart Entry impossible to trigger - * All quality 90+ signals were opening with worse entries than possible - * Fix enables Smart Entry to work as designed (wait for 0.5-2% pullbacks) - * Position sizing bug was actually Smart Entry validation bug in disguise - -69. **Direction-specific leverage thresholds not explicit in code (Fixed Dec 3, 2025):** - - **Symptom:** Leverage assignment code checked `qualityResult.score >= 90` without explicit direction context - - **Risk:** High quality SHORT signal could potentially get LONG leverage configuration (or vice versa) - - **Code Pattern:** - ```typescript - // UNCLEAR CODE (OLD): - let leverage = 1 - if (qualityResult.score >= 90) { - leverage = 5 // Which direction? Not obvious - } else if (qualityResult.score >= 80) { - leverage = 4 - } - ``` - - **User Clarification (Dec 3, 2025):** Quality 90+ → 5x leverage for BOTH LONG and SHORT (intentional design) - - **Fix:** Made direction-specific thresholds explicit in code even though values are same - ```typescript - // EXPLICIT CODE (NEW): - let leverage = 1 - if (body.direction === 'LONG') { - if (qualityResult.score >= 90) leverage = 5 - else if (qualityResult.score >= 80) leverage = 4 - else if (qualityResult.score >= 70) leverage = 3 - else if (qualityResult.score >= 60) leverage = 2 - } else { // SHORT - if (qualityResult.score >= 90) leverage = 5 // Same as LONG but explicit - else if (qualityResult.score >= 80) leverage = 4 - else if (qualityResult.score >= 70) leverage = 3 - else if (qualityResult.score >= 60) leverage = 2 - } - ``` - - **Files Modified:** - * `app/api/trading/execute/route.ts` - Leverage determination logic - - **Git Commit:** 58f812f "Fix Bug #2: Make direction-specific leverage thresholds explicit" - - **Deployed:** Dec 3, 2025, 09:02:45 CET (same container restart as Bug #1) - - **Verification:** User confirmed quality 90+ → 5x for both directions is intentional design - - **Lessons Learned:** - 1. **Make direction context explicit** - Even if values are same, code clarity matters - 2. **Avoid ambiguous conditionals** - Future changes might need different thresholds per direction - 3. **Document intentional symmetry** - Same values for LONG/SHORT is design choice, not oversight - 4. **Code maintainability** - Explicit branches easier to modify when requirements change - - **Why This Matters:** - * Real money trading - leverage misconfiguration causes financial loss - * Future changes may need different thresholds for LONG vs SHORT - * Code clarity prevents future bugs when modifying leverage logic - * Explicit direction handling makes system behavior predictable - -70. **Smart Validation Queue rejected by execute endpoint (CRITICAL - Fixed Dec 3, 2025):** - - **Symptom:** Quality 50-89 signals validated by Smart Validation Queue get rejected by execute endpoint with "Quality score too low" error - - **Root Cause:** Execute endpoint applies quality threshold check AFTER validation queue has already confirmed price action - - **Real Incident (Dec 3, 2025):** - * Signal arrives: Quality 50, direction LONG - * check-risk endpoint: Blocks signal (score < 95 threshold) - * check-risk adds to Smart Validation Queue for monitoring - * Queue watches price for confirmation (±0.3% move) - * Price confirms signal direction → Queue validates entry - * Queue calls execute with validatedEntry=true flag - * **BUG:** Execute endpoint rejects (quality < 95) - * **Result:** User loses validated entry opportunity - - **Impact:** Smart Validation Queue completely non-functional - all validated entries rejected - - **Fix (app/api/trading/execute/route.ts lines 228-242):** - ```typescript - // CRITICAL FIX (Dec 3, 2025): Allow Smart Validation Queue bypasses - const isValidatedEntry = body.validatedEntry === true - - if (isValidatedEntry) { - console.log(`✅ VALIDATED ENTRY BYPASS: Quality ${qualityResult.score} accepted by Smart Validation Queue`) - console.log(` Original quality: ${body.originalQualityScore}, validated after ${body.validationDelayMinutes || 0} minutes`) - console.log(` Bypassing ${minQualityScore} threshold - queue already confirmed price action`) - } - - // Only apply quality threshold if NOT a validated entry - if (!isValidatedEntry && qualityResult.score < minQualityScore) { - return NextResponse.json({ error: 'Quality too low' }, { status: 400 }) - } - ``` - - **How It Works:** - 1. Smart Validation Queue validates quality 50-89 signal via price confirmation - 2. Queue calls execute with validatedEntry=true flag + original metadata - 3. Execute checks flag BEFORE quality threshold check - 4. If validatedEntry=true, bypass quality check entirely - 5. Trade executes with original quality score preserved in database - - **Git Commit:** 785b09e "critical: Fix Bug 1 (revenge external closures) & Bug 5 (validated entry bypass)" - - **Deployed:** Dec 3, 2025 (pending container restart) - - **Files Modified:** - * `app/api/trading/execute/route.ts` - Added validatedEntry bypass logic - - **Integration Points:** - * check-risk endpoint: Adds signals to validation queue when blocked - * smart-validation-queue.ts: Calls execute with validatedEntry=true - * Database: Trade records include validatedEntry, originalQualityScore, validationDelayMinutes - - **Monitoring:** - ```bash - docker logs -f trading-bot-v4 | grep "VALIDATED ENTRY BYPASS" - # Expected: "✅ VALIDATED ENTRY BYPASS: Quality 50 accepted by Smart Validation Queue" - ``` - - **Lessons Learned:** - 1. **Validation bypass flags must be checked FIRST** - Before any rejection logic - 2. **Queue validation supersedes thresholds** - Price confirmation is authoritative - 3. **Preserve original metadata** - originalQualityScore needed for analytics - 4. **Comprehensive logging** - Track bypass events for monitoring effectiveness - 5. **Non-breaking change** - Backward compatible (flag defaults to false) - - **Why This Matters:** - * Smart Validation Queue is profit recovery system (expected +$1,823/month) - * Quality 50-89 signals can be profitable if price confirms direction - * Without bypass, system loses ALL validated entry opportunities - * This fix enables the full validation queue workflow end-to-end - -71. **Revenge system missing external closure integration (CRITICAL - Fixed Dec 3, 2025):** - - **Symptom:** High-quality signals (85+) stopped out by external closures (manual, liquidation, external SL) don't trigger revenge window - - **Root Cause:** Revenge eligibility check only existed in Position Manager's executeExit() path, not in handleExternalClosure() path - - **Real Incident (Nov 20, 2025 - motivation):** - * v8 signal: Quality 90, ADX 26, SHORT at $141.37 - * Called exact top, stopped at $142.48 for -$138.35 loss - * Price then dropped to $131.32 (8.8% move, +$490 opportunity) - * **No revenge activated** - external closure bypassed eligibility check - * **Missed profit:** Could have recovered loss + captured $350+ profit - - **Impact:** Every external closure for quality 85+ signals loses revenge opportunity - - **Fix (lib/trading/position-manager.ts lines 1001-1019):** - ```typescript - console.log(`💾 External closure recorded: ${exitReason} at $${currentPrice} | P&L: $${totalRealizedPnL.toFixed(2)}`) - - // CRITICAL FIX (Dec 3, 2025): Enable revenge trading for external closures - if (exitReason === 'SL' && trade.signalQualityScore && trade.signalQualityScore >= 85) { - console.log(`🎯 External SL closure - Quality ${trade.signalQualityScore} >= 85, checking revenge eligibility`) - try { - const stopHuntTracker = getStopHuntTracker() - await stopHuntTracker.recordStopHunt({ - originalTradeId: trade.id, - symbol: trade.symbol, - direction: trade.direction, - stopHuntPrice: currentPrice, - originalEntryPrice: trade.entryPrice, - originalQualityScore: trade.signalQualityScore, - stopLossAmount: Math.abs(totalRealizedPnL) - }) - console.log(`✅ Revenge window activated for external closure (30min monitoring)`) - } catch (error) { - console.error(`❌ Failed to record stop hunt for external closure:`, error) - } - } - ``` - - **How It Works:** - 1. External closure detected (position closed by manual/liquidation/external SL) - 2. Position Manager saves closure to database - 3. **NEW:** Check if exitReason='SL' AND signalQualityScore exists AND >= 85 - 4. If yes, call stopHuntTracker.recordStopHunt() with trade details - 5. This activates 30-minute revenge monitoring window - 6. If price reverses back through original entry + 0.5% buffer within 30 minutes - 7. System automatically enters revenge trade with same position size - - **TypeScript Safety:** - * Added null check: `trade.signalQualityScore && trade.signalQualityScore >= 85` - * Prevents "possibly undefined" compilation errors - * Ensures field exists before comparison - - **Git Commit:** 785b09e "critical: Fix Bug 1 (revenge external closures) & Bug 5 (validated entry bypass)" - - **Deployed:** Dec 3, 2025 (pending container restart) - - **Files Modified:** - * `lib/trading/position-manager.ts` - Added revenge check after external closure DB save - - **Integration Points:** - * stop-hunt-tracker.ts: Records stop hunt to database, monitors for reversal - * Database: StopHunt table tracks revenge window (4 hours), revengeExecuted flag - * Telegram: Sends "🔥 REVENGE TRADE ACTIVATED" notification when revenge triggers - - **Monitoring:** - ```bash - docker logs -f trading-bot-v4 | grep -E "External SL closure|Revenge window activated" - # Expected: "✅ Revenge window activated for external closure (30min monitoring)" - ``` - - **Why 30 Minutes (Nov 26, 2025 - Changed from 4 hours):** - * Original revenge system: 4-hour window for direct executeExit() path - * **NEW for external closures:** 30-minute window (shorter, focused) - * **Rationale:** External closures are immediate events (not gradual stop-outs) - * Price reversal patterns happen quickly after stop hunts - * 30 minutes captures most reversals without excessive monitoring - * Reduces false triggers from longer-term price movements - - **Lessons Learned:** - 1. **Check ALL exit paths** - External closures are separate code path from executeExit() - 2. **Null safety for optional fields** - Always check existence before comparison - 3. **Error handling essential** - Revenge tracking failure shouldn't crash closure handler - 4. **Comprehensive logging** - Track revenge activation for monitoring effectiveness - 5. **Window tuning** - External closures need shorter revenge window than gradual stops - - **Why This Matters:** - * External closures (manual, liquidation, external SL) are common exit scenarios - * Quality 85+ signals are high-probability setups worth recovering - * Revenge system recovers ~70% of stop-out losses (historical data) - * Without this fix, external closures lose ALL revenge opportunities - * This completes revenge system coverage for all exit scenarios - -54. **Telegram webhook conflicts with polling bot (CRITICAL - Fixed Dec 4, 2025):** - - **Symptom:** Python Telegram bot crashes with "Conflict: can't use getUpdates method while webhook is active" - - **User report:** `/status` command returns weird n8n test message: "✅ Bot works! You said: {{ $json.message.text }}" - - **Root Cause:** n8n had active Telegram webhook that intercepted ALL messages before Python bot could receive them - - **Why it broke:** - * Telegram API only allows ONE update method: either webhooks OR polling, not both - * n8n workflow set webhook at `https://flow.egonetix.de/webhook/93b61e0a-f509-4994-9f28-b16468c90ac7/webhook` - * Python bot using polling (`getUpdates`) crashed immediately - * n8n webhook sent test messages with broken template syntax (missing `=` in `{{ }}`) - - **Real incident (Dec 4, 2025):** - * User sent `/status` → received "✅ Bot works! You said: {{ $json.message.text }}" - * Python bot logs showed continuous crashes: `telegram.error.Conflict: can't use getUpdates` - * Bot running but couldn't process ANY commands - * Container healthy but functionality broken - - **Detection:** - ```bash - # Check webhook status - curl -s "https://api.telegram.org/bot{TOKEN}/getWebhookInfo" | python3 -m json.tool - # Shows: "url": "https://flow.egonetix.de/webhook/..." (webhook active) - - # Check bot logs - docker logs telegram-trade-bot - # Shows: telegram.error.Conflict (webhook blocking polling) - ``` - - **Fix (Dec 4, 2025):** - ```bash - # Delete Telegram webhook - curl -s "https://api.telegram.org/bot{TOKEN}/deleteWebhook" - # Response: {"ok": true, "result": true, "description": "Webhook was deleted"} - - # Restart Python bot - docker restart telegram-trade-bot - - # Verify webhook removed - curl -s "https://api.telegram.org/bot{TOKEN}/getWebhookInfo" - # Shows: "url": "" (empty = polling can work) - ``` - - **Impact:** Python bot now receives all messages via polling, `/status` works correctly - - **Architecture decision:** Cannot run both n8n webhook AND Python polling bot simultaneously - - **Options going forward:** - * **Option A (CURRENT):** Python bot with polling - handles `/status`, manual trades, position queries - * **Option B:** n8n webhook only - disable Python bot, handle commands in n8n workflows - - **Lesson:** Telegram API architecture restriction - must choose polling OR webhook, cannot have both - - **Prevention:** If n8n needs Telegram integration in future, either: - 1. Disable Python bot first, OR - 2. Use Python bot only, don't set Telegram webhooks in n8n - - **Git commit:** N/A (configuration fix, no code changes) - - **Status:** ✅ Fixed and verified working (user confirmed `/status` responds correctly) +**⚠️ CRITICAL REFERENCE: See `docs/COMMON_PITFALLS.md` for complete list (72 documented issues)** + +This section contains the **TOP 10 MOST CRITICAL** pitfalls that every AI agent must know.

Drift SDK Memory Leak (#1)** - JavaScript heap OOM after 10+ hours +- **Solution:** Smart error-based health monitoring (`lib/monitoring/drift-health-monitor.ts`) +- **Detection:** `interceptWebSocketErrors()` patches console.error +- **Action:** Restarts if 50+ errors in 30-second window +- **Status:** Fixed Nov 15, 2025, Enhanced Nov 24, 2025 + +**2. Wrong RPC Provider (#2)** - Alchemy breaks Drift SDK subscriptions +- **FINAL CONCLUSION:** Use Helius RPC, NEVER use Alchemy +- **Root Cause:** Alchemy rate limits break Drift's burst subscription pattern +- **Evidence:** 17-71 subscription errors with Alchemy vs 0 with Helius +- **Status:** Investigation Complete Nov 14, 2025 + +**3. P&L Compounding Race Condition (#48, #49, #59, #60, #61, #67)** +- **Pattern:** Multiple monitoring loops detect same closure → each adds P&L +- **Result:** $6 real → $92 recorded (15x inflation) +- **Fix:** Use `Map.delete()` atomic return as deduplication lock (Dec 2, 2025) +- **Code:** `if (!this.activeTrades.delete(tradeId)) return` - first caller wins + +**4. Database-First Pattern (#29)** - Save DB before Position Manager +- **Rule:** `createTrade()` MUST succeed before `positionManager.addTrade()` +- **Why:** If DB fails, API returns 500 with "CLOSE POSITION MANUALLY" +- **Impact:** Without this, positions become untracked on container restart +- **Status:** Fixed Nov 13, 2025 + +**5. Container Deployment Verification (#31)** +- **Rule:** NEVER say "fixed" without checking container timestamp +- **Verification:** `docker logs trading-bot-v4 | grep "Server starting"` vs `git log -1 --format='%ai'` +- **If container older than commit:** CODE NOT DEPLOYED, FIX NOT ACTIVE +- **Status:** Critical lesson from Nov 13, 2025 incident + +**6. Position.size Tokens vs USD (#24)** - SDK returns tokens, not USD +- **Bug:** Comparing 12.28 tokens to $1,950 → "99.4% reduction" → false TP1 +- **Fix:** `positionSizeUSD = Math.abs(position.size) * currentPrice` +- **Impact:** Without fix, TP1 never triggers correctly +- **Status:** Fixed Nov 12, 2025 + +**7. Ghost Detection Atomic Lock (#67)** - Map.delete() as deduplication +- **Pattern:** Async handlers called by multiple code paths simultaneously +- **Solution:** `if (!this.activeTrades.delete(tradeId)) { return }` - atomic lock +- **Why:** JavaScript Map.delete() returns true only for first caller +- **Status:** Fixed Dec 2, 2025 + +**8. Smart Entry Wrong Price (#66, #68)** - Use Pyth price, not webhook +- **Bug #66:** Symbol format mismatch ("SOLUSDT" vs "SOL-PERP") caused cache miss +- **Bug #68:** Webhook `signal.price` contained percentage (70.80) not market price ($142) +- **Fix:** Always use `pythClient.getPrice(symbol)` for calculations +- **Status:** Fixed Dec 1-3, 2025 + +**9. MFE/MAE Wrong Units (#54)** - Store percentages, not dollars +- **Bug:** Storing $64.08 when should store 0.48% (133× inflation) +- **Fix:** `trade.maxFavorableExcursion = profitPercent` not `currentPnLDollars` +- **Impact:** Analytics completely wrong for all trades +- **Status:** Fixed Nov 23, 2025 + +**10. Execute Endpoint Quality Bypass (#62)** - Quality check after timeframe validation +- **Bug:** Quality calculated but never validated → trades at quality 30 executed +- **Fix:** Add explicit quality check AFTER timeframe confirmation +- **Code:** `if (qualityResult.score < minQualityScore) return 400` +- **Status:** Fixed Nov 27, 2025 + +--- + +### Quick Links by Category + +**P&L Calculation Errors:** #11, #41, #48, #49, #54, #57, #61 +**Race Conditions:** #27, #28, #59, #60, #67 +**SDK/API Issues:** #1, #2, #12, #24, #36, #45 +**Database Operations:** #29, #35, #37, #50, #58 +**Configuration:** #55, #62 +**Smart Entry:** #63, #66, #68, #70 +**Deployment:** #31, #47 + +📚 **Full Documentation:** `docs/COMMON_PITFALLS.md` (72 pitfalls with code examples, git commits, deployment dates) ## File Conventions diff --git a/docs/COMMON_PITFALLS.md b/docs/COMMON_PITFALLS.md new file mode 100644 index 0000000..a908dfa --- /dev/null +++ b/docs/COMMON_PITFALLS.md @@ -0,0 +1,1493 @@ +# Common Pitfalls Reference Documentation + +> **Last Updated:** December 4, 2025 +> **Total Documented:** 71 Pitfalls +> **Primary Source:** `.github/copilot-instructions.md` + +## Purpose + +This document is the **comprehensive reference** for all documented pitfalls, bugs, and lessons learned from the Trading Bot v4 project.
