From 78757d211154e99fa715b3d42d05e568a7cd2874 Mon Sep 17 00:00:00 2001 From: mindesbunister Date: Sun, 30 Nov 2025 23:08:34 +0100 Subject: [PATCH] critical: Fix FALSE TP1 detection - add price verification (Pitfall #63) CRITICAL BUG FIXED (Nov 30, 2025): Position Manager was setting tp1Hit=true based ONLY on size mismatch, without verifying price actually reached TP1 target. This caused: - Premature order cancellation (on-chain TP1 removed before fill) - Lost profit potential (optimal exits missed) - Ghost orders after container restarts ROOT CAUSE (line 1086 in position-manager.ts): trade.tp1Hit = true // Set without checking this.shouldTakeProfit1() FIX IMPLEMENTED: - Added price verification: this.shouldTakeProfit1(currentPrice, trade) - Only set tp1Hit when BOTH conditions met: 1. Size reduced by 5%+ (positionSizeUSD < trade.currentSize * 0.95) 2. Price crossed TP1 target (this.shouldTakeProfit1 returns true) - Verbose logging for debugging (shows price vs target, size ratio) - Fallback: Update tracked size but don't trigger TP1 logic REAL INCIDENT: - Trade cmim4ggkr00canv07pgve2to9 (SHORT SOL-PERP Nov 30) - TP1 target: $137.07, actual exit: $136.84 - False detection triggered premature order cancellation - Position closed successfully but system integrity compromised FILES CHANGED: - lib/trading/position-manager.ts (lines 1082-1111) - CRITICAL_TP1_FALSE_DETECTION_BUG.md (comprehensive incident report) TESTING REQUIRED: - Monitor next trade with TP1 for correct detection - Verify logs show TP1 VERIFIED or TP1 price NOT reached - Confirm no premature order cancellation ALSO FIXED: - Restarted telegram-trade-bot to fix /status command conflict See: Common Pitfall #63 in copilot-instructions.md (to be added) --- CRITICAL_TP1_FALSE_DETECTION_BUG.md | 266 ++++++++++++++++++++++++++++ lib/trading/position-manager.ts | 34 +++- 2 files changed, 296 insertions(+), 4 deletions(-) create mode 100644 CRITICAL_TP1_FALSE_DETECTION_BUG.md diff --git a/CRITICAL_TP1_FALSE_DETECTION_BUG.md b/CRITICAL_TP1_FALSE_DETECTION_BUG.md new file mode 100644 index 0000000..475adeb --- /dev/null +++ b/CRITICAL_TP1_FALSE_DETECTION_BUG.md @@ -0,0 +1,266 @@ +# CRITICAL: TP1 False Detection Bug - Financial Loss Risk + +**Date:** Nov 30, 2025 +**Severity:** 🔴 CRITICAL - Causes premature order cancellation, lost profit potential +**Status:** 🔧 FIXING NOW + +## Real Incident (Nov 30, 2025, 19:37-21:22 UTC) + +**Trade ID:** cmim4ggkr00canv07pgve2to9 +**Symbol:** SOL-PERP SHORT +**Entry:** $137.76 +**Position:** $89.10 +**TP1 Target:** $137.07 (0.5%, 75% close) +**Actual Exit:** $136.84 via external closure (on-chain TP1 order filled) +**P&L:** $0.23 (should have been higher with proper order management) + +## The Bug Chain + +### 1. False TP1 Detection (Position Manager lines 1002-1087) + +**Root Cause:** Position Manager detects size mismatch and IMMEDIATELY sets `trade.tp1Hit = true` WITHOUT verifying price reached TP1 target. + +**Vulnerable Code:** +```typescript +// Line 1002-1087 in lib/trading/position-manager.ts +if (positionSizeUSD < trade.currentSize * 0.95) { // 5% tolerance + console.log(`⚠️ Position size mismatch: expected $${trade.currentSize.toFixed(2)}, got $${positionSizeUSD.toFixed(2)}`) + + // ... various checks for signal flip, phantom trade, etc. ... + + // BUG: Sets tp1Hit = true based on SIZE MISMATCH, not PRICE TARGET + trade.currentSize = positionSizeUSD + trade.tp1Hit = true // ← CRITICAL BUG: No price verification! + await this.saveTradeState(trade) +} +``` + +**Why This Happens:** +- On-chain TP1 order fills when price crosses $137.07 +- Drift position size reduces from $89.10 → ~$22 (75% closed) +- Position Manager monitoring loop detects size mismatch +- ASSUMES any size reduction = TP1 hit (WRONG!) +- Could be partial fill due to slippage, could be external closure, could be anything + +### 2. Premature Order Cancellation (Lines 1228-1284) + +After setting `trade.tp1Hit = true`, Position Manager executes: + +```typescript +// Line 1228-1257: Cancel ALL orders on the symbol +console.log('🗑️ Cancelling old stop loss orders...') +const { cancelAllOrders, placeExitOrders } = await import('../drift/orders') +const cancelResult = await cancelAllOrders(trade.symbol) + +// BUG: This cancels the on-chain TP1 order that's about to fill! +``` + +**Consequence:** On-chain TP1 limit order ($137.07) gets cancelled by Position Manager BEFORE it can fill at optimal price. + +### 3.
