CRITICAL FIX: Prevent unprotected positions via database-first pattern
Root Cause: - Execute endpoint saved to database AFTER adding to Position Manager - Database save failures were silently caught and ignored - API returned success even when DB save failed - Container restarts lost in-memory Position Manager state - Result: Unprotected positions with no TP/SL monitoring Fixes Applied: 1. Database-First Pattern (app/api/trading/execute/route.ts): - MOVED createTrade() BEFORE positionManager.addTrade() - If database save fails, return HTTP 500 with critical error - Error message: 'CLOSE POSITION MANUALLY IMMEDIATELY' - Position Manager only tracks database-persisted trades - Ensures container restarts can restore all positions 2. Transaction Timeout (lib/drift/orders.ts): - Added 30s timeout to confirmTransaction() in closePosition() - Prevents API from hanging during network congestion - Uses Promise.race() pattern for timeout enforcement 3. Telegram Error Messages (telegram_command_bot.py): - Parse JSON for ALL responses (not just 200 OK) - Extract detailed error messages from 'message' field - Shows critical warnings to user immediately - Fail-open: proceeds if analytics check fails 4. Position Manager (lib/trading/position-manager.ts): - Move lastPrice update to TOP of monitoring loop - Ensures /status endpoint always shows current price Verification: - Test trade cmhxj8qxl0000od076m21l58z executed successfully - Database save completed BEFORE Position Manager tracking - SL triggered correctly at -$4.21 after 15 minutes - All protection systems working as expected Impact: - Eliminates risk of unprotected positions - Provides immediate critical warnings if DB fails - Enables safe container restarts with full position recovery - Verified with live test trade on production See: CRITICAL_INCIDENT_UNPROTECTED_POSITION.md for full incident report

# CRITICAL INCIDENT: Unprotected Position (Nov 13, 2025)
|
||||
|
||||
## Summary
|
||||
User opened SOL SHORT via Telegram command. Position opened on Drift but was NOT tracked by Position Manager, resulting in NO TP/SL orders and -$5.40 loss when manually closed.
|
||||
|
||||
## Timeline
|
||||
- **~14:00 CET**: User sends `short sol` via Telegram
|
||||
- **14:14 CET**: Container restarts (unknown reason)
|
||||
- **~15:10 CET**: User notices position has no TP/SL in Drift UI
|
||||
- **15:15 CET**: User manually closes position at -$5.40 loss
|
||||
- **15:20 CET**: Investigation begins
|
||||
|
||||
## Root Cause Analysis
|
||||
|
||||
### Primary Cause: Database Save Failure Silently Ignored
|
||||
**File:** `app/api/trading/execute/route.ts` lines 508-512 (original)
|
||||
|
||||
**The Bug:**
|
||||
```typescript
|
||||
// Add to position manager for monitoring AFTER orders are placed
|
||||
await positionManager.addTrade(activeTrade)
|
||||
|
||||
// ... later in code ...
|
||||
|
||||
// Save trade to database
|
||||
try {
|
||||
await createTrade({...})
|
||||
} catch (dbError) {
|
||||
console.error('❌ Failed to save trade to database:', dbError)
|
||||
// Don't fail the trade if database save fails ← THIS IS THE BUG
|
||||
}
|
||||
```
|
||||
|
||||
**What Happened:**
|
||||
1. Position opened successfully on Drift ✅
|
||||
2. Exit orders placed on-chain ✅ (probably)
|
||||
3. Trade added to Position Manager in-memory ✅
|
||||
4. Database save FAILED ❌ (error caught and logged)
|
||||
5. API returned `success: true` to user ✅ (user didn't know save failed)
|
||||
6. Container restarted at 14:14 CET
|
||||
7. Position Manager restoration logic queries database for open trades
|
||||
8. **Trade not in database** → Position Manager didn't monitor it ❌
|
||||
9. Exit orders may have been canceled during restart or never placed
|
||||
10. Position left completely unprotected
|
||||
|
||||
### Contributing Factors
|
||||
|
||||
#### Factor 1: Container Restart Lost In-Memory State
|
||||
- Position Manager tracks trades in a `Map<string, ActiveTrade>`
|
||||
- Container restart at 14:14 CET cleared all in-memory state
|
||||
- Restoration logic relies on database query:
|
||||
```typescript
|
||||
const openTrades = await prisma.trade.findMany({
|
||||
where: { exitReason: null }
|
||||
})
|
||||
```
|
||||
- Since trade wasn't in DB, restoration failed silently
|
||||
|
||||
#### Factor 2: Ghost Trades Corrupting Database
|
||||
Two trades found with `stopLossPrice=0`:
|
||||
- `cmhkeenei0002nz07nl04uub8` (Nov 4, $70.35 entry)
|
||||
- `cmho7ki8u000aof07k7lpivb0` (Nov 7, $119.18 entry)
|
||||
|
||||
These may have caused database schema issues or validation errors during the failed save.
|
||||
|
||||
#### Factor 3: No Database Save Verification
|
||||
- Execute endpoint doesn't verify `createTrade()` succeeded before returning success
|
||||
- User had no way to know their position was unprotected
|
||||
- Telegram bot showed "success" message despite database failure
|
||||
|
||||
## The Fix
|
||||
|
||||
### Fix 1: Database-First Pattern (CRITICAL)
|
||||
**File:** `app/api/trading/execute/route.ts`
|
||||
|
||||
**Before:**
|
||||
```typescript
|
||||
await positionManager.addTrade(activeTrade) // Add to memory FIRST
|
||||
// ... create response ...
|
||||
try {
|
||||
await createTrade({...}) // Save to DB LATER
|
||||
} catch (dbError) {
|
||||
// Ignore error ← WRONG
|
||||
}
|
||||
```
|
||||
|
||||
**After:**
|
||||
```typescript
|
||||
try {
|
||||
await createTrade({...}) // Save to DB FIRST
|
||||
} 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.'
|
||||
}, { status: 500 })
|
||||
}
|
||||
|
||||
// ONLY add to Position Manager if database save succeeded
|
||||
await positionManager.addTrade(activeTrade)
|
||||
```
|
||||
|
||||
**Impact:**
|
||||
- If database save fails, API returns error
|
||||
- User/Telegram bot gets failure notification
|
||||
- Position Manager is NOT given the trade to monitor
|
||||
- User knows to close position manually on Drift UI
|
||||
- Prevents silent failures
|
||||
|
||||
### Fix 2: Transaction Confirmation Timeout
|
||||
**File:** `lib/drift/orders.ts` (closePosition function)
|
||||
|
||||
**Problem:** `connection.confirmTransaction()` could hang indefinitely, blocking API
|
||||
|
||||
**Fix:**
|
||||
```typescript
|
||||
const confirmationPromise = connection.confirmTransaction(txSig, 'confirmed')
|
||||
const timeoutPromise = new Promise((_, reject) =>
|
||||
setTimeout(() => reject(new Error('Transaction confirmation timeout')), 30000)
|
||||
)
|
||||
|
||||
const confirmation = await Promise.race([confirmationPromise, timeoutPromise])
|
||||
```
|
||||
|
||||
**Impact:**
|
||||
- Close API won't hang forever
|
||||
- 30s timeout allows user to retry or check Drift UI
|
||||
- Logs warning if timeout occurs
|
||||
|
||||
### Fix 3: Ghost Trade Cleanup
|
||||
**Database:** Marked 2 corrupted trades as closed
|
||||
|
||||
```sql
|
||||
UPDATE "Trade"
|
||||
SET "exitReason" = 'ghost_trade_cleanup',
|
||||
"exitPrice" = "entryPrice",
|
||||
"realizedPnL" = 0
|
||||
WHERE id IN ('cmho7ki8u000aof07k7lpivb0', 'cmhkeenei0002nz07nl04uub8');
|
||||
```
|
||||
|
||||
**Impact:**
|
||||
- Position Manager restoration no longer blocked by invalid data
|
||||
- Database queries for open trades won't return corrupted entries
|
||||
|
||||
## Lessons Learned
|
||||
|
||||
### 1. NEVER Silently Swallow Critical Errors
|
||||
**Bad Pattern:**
|
||||
```typescript
|
||||
try {
|
||||
await criticalOperation()
|
||||
} catch (err) {
|
||||
console.error('Error:', err)
|
||||
// Continue anyway ← WRONG
|
||||
}
|
||||
```
|
||||
|
||||
**Good Pattern:**
|
||||
```typescript
|
||||
try {
|
||||
await criticalOperation()
|
||||
} catch (err) {
|
||||
console.error('CRITICAL ERROR:', err)
|
||||
return errorResponse() // FAIL FAST
|
||||
}
|
||||
```
|
||||
|
||||
### 2. Database-First for Stateful Operations
|
||||
When in-memory state depends on database:
|
||||
1. Save to database FIRST
|
||||
2. Verify save succeeded
|
||||
3. THEN update in-memory state
|
||||
4. If any step fails, ROLL BACK or return error
|
||||
|
||||
### 3. Container Restart Resilience
|
||||
- In-memory state is VOLATILE
|
||||
- Critical state must persist to database
|
||||
- Restoration logic must handle:
|
||||
- Corrupted data
|
||||
- Missing fields
|
||||
- Schema mismatches
|
||||
|
||||
### 4. User Notifications for Failures
|
||||
- API errors must propagate to user
|
||||
- Telegram bot must show FAILURE messages
|
||||
- Don't hide errors from users - they need to know!
|
||||
|
||||
### 5. Verification Mandate Still Critical
|
||||
- Even after this incident, we didn't verify the fix worked with real trade
|
||||
- ALWAYS execute test trade after deploying financial code changes
|
||||
- Monitor logs to ensure expected behavior
|
||||
|
||||
## Prevention Measures
|
||||
|
||||
### Immediate (Deployed)
|
||||
- ✅ Database save moved before Position Manager add
|
||||
- ✅ Transaction confirmation timeout (30s)
|
||||
- ✅ Ghost trades cleaned from database
|
||||
|
||||
### Short-Term (To Do)
|
||||
- [ ] Add database save health check on startup
|
||||
- [ ] Create `/api/admin/sync-positions` endpoint to reconcile Drift vs Database
|
||||
- [ ] Add Telegram alert when trade save fails
|
||||
- [ ] Log database errors to SystemEvent table for monitoring
|
||||
|
||||
### Long-Term (Future)
|
||||
- [ ] Implement database transactions (savepoint before trade execution)
|
||||
- [ ] Add automatic position sync check every 5 minutes
|
||||
- [ ] Create "orphaned position" detection (on Drift but not in DB)
|
||||
- [ ] Add Sentry/error tracking for database failures
|
||||
- [ ] Consider Redis/in-memory DB for critical state (survives restarts)
|
||||
|
||||
## Financial Impact
|
||||
- **Loss:** -$5.40
|
||||
- **Risk Exposure:** Unlimited (position had no stop loss)
|
||||
- **Duration Unprotected:** ~1 hour
|
||||
- **Prevented Loss:** Unknown (market could have moved significantly)
|
||||
|
||||
## Status
|
||||
- ✅ Position closed manually
|
||||
- ✅ Fixes implemented and deployed
|
||||
- ✅ Ghost trades cleaned
|
||||
- ⏳ Container rebuilding with fixes
|
||||
- ⏳ Need test trade to verify fixes
|
||||
|
||||
## Next Steps
|
||||
1. Wait for container rebuild to complete
|
||||
2. Test with small position ($10-20)
|
||||
3. Verify database save succeeds before Position Manager add
|
||||
4. Monitor for any database errors
|
||||
5. Consider reducing position size until system proven stable
