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:

// 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:

  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:

await positionManager.addTrade(activeTrade)  // Add to memory FIRST
// ... create response ...
try {
  await createTrade({...})  // Save to DB LATER
} catch (dbError) {
  // Ignore error  ← WRONG
}

After:

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:

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

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:

try {
  await criticalOperation()
} catch (err) {
  console.error('Error:', err)
  // Continue anyway  ← WRONG
}

Good Pattern:

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
