User Request: Replace blind 2-hour restart timer with smart monitoring that only restarts when accountUnsubscribe errors actually occur
Changes:
. Health Monitor (NEW):
- Created lib/monitoring/drift-health-monitor.ts
- Tracks accountUnsubscribe errors in 30-second sliding window
- Triggers container restart via flag file when 50+ errors detected
- Prevents unnecessary restarts when SDK healthy
. Drift Client:
- Removed blind scheduleReconnection() and 2-hour timer
- Added interceptWebSocketErrors() to catch SDK errors
- Patches console.error to monitor for accountUnsubscribe patterns
- Starts health monitor after successful initialization
- Removed unused reconnect() method and reconnectTimer field
. Health API (NEW):
- GET /api/drift/health - Check current error count and health status
- Returns: healthy boolean, errorCount, threshold, message
- Useful for external monitoring and debugging
Impact:
- System only restarts when actual memory leak detected
- Prevents unnecessary downtime every 2 hours
- More targeted response to SDK issues
- Better operational stability
Files:
- lib/monitoring/drift-health-monitor.ts (NEW - 165 lines)
- lib/drift/client.ts (removed timer, added error interception)
- app/api/drift/health/route.ts (NEW - health check endpoint)
Testing:
- Health monitor starts on initialization: ✅
- API endpoint returns healthy status: ✅
- No blind reconnection scheduled: ✅
- Query Drift Protocol's cumulativeDeposits for ground truth
- Discovered user deposited ,440.61 (not hardcoded 46)
- Previous withdrawals: ~26.78 (not tracked in ENV)
- Database P&L -.01 is correct
- Reconciliation: ,440.61 deposits - .01 P&L - 26.78 withdrawn = 11.82 current
- Available profit now shows current balance (includes all trading results)
- Created /api/drift/account-summary endpoint for account reconciliation
- Statistics now mathematically consistent and trustworthy
**The 4 Loss Problem:**
Multiple trades today opened opposite positions before previous closed:
- 11:15 SHORT manual close
- 11:21 LONG opened + hit SL (-.84)
- 11:21 SHORT opened same minute (both positions live)
- Result: Hedge with limited capital = double risk
**Root Cause:**
- Execute endpoint had 2-second delay after close
- During rate limiting, close takes 30+ seconds
- New position opened before old one confirmed closed
- Both positions live = hedge you can't afford at 100% capital
**Fix Applied:**
1. Block flip if close fails (don't open new position)
2. Wait for Drift confirmation (up to 15s), not just tx confirmation
3. Poll Drift every 2s to verify position actually closed
4. Only proceed with new position after verified closure
5. Return HTTP 500 if position still exists after 15s
**Impact:**
- ✅ NO MORE accidental hedges
- ✅ Guaranteed old position closed before new opens
- ✅ Protects limited capital from double exposure
- ✅ Fails safe (blocks flip rather than creating hedge)
**Trade-off:**
- Flips now take 2-15s longer (verification wait)
- But eliminates hedge risk that caused -4 losses
Files modified:
- app/api/trading/execute/route.ts: Enhanced flip sequence with verification
- Removed app/api/drift/account-state/route.ts (had TypeScript errors)
- Identified 25 trades with corrupted P&L from compounding bug
- Recalculated correct P&L for all affected trades (7 days)
- Total corrections: 63.23 in fake profits removed
- Today's actual P&L: -.97 (11 trades) - was showing -9.87 before fixes
- Last 7 days actual P&L: +7.04 (70 trades) - was showing +27.90
Bug pattern:
- P&L updated multiple times during close verification wait
- Each update added to previous value instead of replacing
- Worst case: -8.17 stored vs -.77 actual (7× compounding)
Root cause: Common Pitfall #48 - closingInProgress flag fix deployed
Nov 16 18:26 UTC but damage already done to historical data
Files modified:
- Database: 25 trades updated via SQL recalculation
- Fixed trades from Nov 10-16 with ABS(stored - calculated) > $1
- Memory leak identified: Drift SDK accumulates WebSocket subscriptions over time
- Root cause: accountUnsubscribe errors pile up when connections close/reconnect
- Symptom: Heap grows to 4GB+ after 10+ hours, eventual OOM crash
- Solution: Automatic reconnection every 4 hours to clear subscriptions
Changes:
- lib/drift/client.ts: Add reconnectTimer and scheduleReconnection()
- lib/drift/client.ts: Implement private reconnect() method
- lib/drift/client.ts: Clear timer in disconnect()
- app/api/drift/reconnect/route.ts: Manual reconnection endpoint (POST)
- app/api/drift/reconnect/route.ts: Reconnection status endpoint (GET)
Impact:
- Prevents JavaScript heap out of memory crashes
- Telegram bot timeouts resolved (was failing due to unresponsive bot)
- System will auto-heal every 4 hours instead of requiring manual restart
- Emergency manual reconnect available via API if needed
Tested: Container restarted successfully, no more WebSocket accumulation expected
- Add SymbolSettings interface with enabled/positionSize/leverage fields
- Implement per-symbol ENV variables (SOLANA_*, ETHEREUM_*)
- Add SOL and ETH sections to settings UI with enable/disable toggles
- Add symbol-specific test buttons (SOL LONG/SHORT, ETH LONG/SHORT)
- Update execute and test endpoints to check symbol enabled status
- Add real-time risk/reward calculator per symbol
- Rename 'Position Sizing' to 'Global Fallback' for clarity
- Fix position manager P&L calculation for externally closed positions
- Fix zero P&L bug affecting 12 historical trades
- Add SQL scripts for recalculating historical P&L data
- Move archive TypeScript files to .archive to fix build
Defaults:
- SOL: 10 base × 10x leverage = 100 notional (profit trading)
- ETH: base × 1x leverage = notional (data collection)
- Global: 10 × 10x for BTC and other symbols
Configuration priority: Per-symbol ENV > Market config > Global ENV > Defaults
