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
