+# ATR-Based Trailing Stop Fix - Nov 11, 2025
+
+## Problem Identified
+
+**Critical Bug:** Runner system was using FIXED 0.3% trailing stop, causing profitable runners to exit immediately.
+
+**Evidence:**
+- Recent trades showing MFE of +7-9% but exiting for losses or minimal gains
+- Example: Entry $167.82, MFE +7.01%, exit $168.91 for **-$2.68 loss**
+- At $168 SOL price: 0.3% = only **$0.50 wiggle room** before stop hits
+- Normal price volatility easily triggers 0.3% retracement
+
+**Documentation Claim vs Reality:**
+- Docs claimed "ATR-based trailing stop" 
+- Code was using `this.config.trailingStopPercent` (fixed 0.3%)
+- Config already had `trailingStopAtrMultiplier` parameter but it wasn't being used!
+
+## Solution Implemented
+
+### 1. Position Manager Update (`lib/trading/position-manager.ts`)
+**Changed trailing stop calculation from fixed to ATR-based:**
+
+```typescript
+// OLD (BROKEN):
+const trailingStopPrice = this.calculatePrice(
+  trade.peakPrice,
+  -this.config.trailingStopPercent, // Fixed 0.3%
+  trade.direction
+)
+
+// NEW (FIXED):
+if (trade.atrAtEntry && trade.atrAtEntry > 0) {
+  // ATR-based: Use ATR% * multiplier
+  const atrPercent = (trade.atrAtEntry / currentPrice) * 100
+  const rawDistance = atrPercent * this.config.trailingStopAtrMultiplier
+  
+  // Clamp between min and max
+  trailingDistancePercent = Math.max(
+    this.config.trailingStopMinPercent,
+    Math.min(this.config.trailingStopMaxPercent, rawDistance)
+  )
+} else {
+  // Fallback to configured percent with clamping
+  trailingDistancePercent = Math.max(
+    this.config.trailingStopMinPercent,
+    Math.min(this.config.trailingStopMaxPercent, this.config.trailingStopPercent)
+  )
+}
+```
+
+### 2. Added `atrAtEntry` to ActiveTrade Interface
+```typescript
+export interface ActiveTrade {
+  // Entry details
+  entryPrice: number
+  entryTime: number
+  positionSize: number
+  leverage: number
+  atrAtEntry?: number // NEW: ATR value at entry for ATR-based trailing stop
+  // ...
+}
+```
+
+### 3. Settings UI Updates (`app/settings/page.tsx`)
+Added new fields for ATR trailing configuration:
+- **ATR Trailing Multiplier** (1.0-3.0x, default 1.5x)
+- **Min Trailing Distance** (0.1-1.0%, default 0.25%)
+- **Max Trailing Distance** (0.5-2.0%, default 0.9%)
+- Changed "Trailing Stop Distance" label to "[FALLBACK]"
+
+### 4. Environment Variables (`.env.example`)
+```bash
+# ATR-based Trailing Stop (for 25% runner after TP2)
+# Trailing distance = (ATR × multiplier)
+# Example: 0.5% ATR × 1.5 = 0.75% trailing (more room than fixed 0.3%)
+TRAILING_STOP_ATR_MULTIPLIER=1.5
+TRAILING_STOP_MIN_PERCENT=0.25
+TRAILING_STOP_MAX_PERCENT=0.9
+TRAILING_STOP_ACTIVATION=0.5
+```
+
+## Expected Impact
+
+### Before Fix (0.3% Fixed)
+- SOL at $168: 0.3% = $0.50 wiggle room
+- Normal 2-minute oscillation kills runner immediately
+- Runners with +7-9% MFE captured minimal profit or even lost money
+
+### After Fix (ATR-based)
+**Recent ATR distribution from database:**
+```sql
+-- Most common ATR values: 0.25-0.52%
+-- At 1.5x multiplier:
+0.25% ATR × 1.5 = 0.375% trail
+0.37% ATR × 1.5 = 0.555% trail  
+0.45% ATR × 1.5 = 0.675% trail
+0.52% ATR × 1.5 = 0.780% trail
+```
+
+**Typical improvement:**
+- Old: $0.50 wiggle room ($168 × 0.3%)
+- New: $1.12 wiggle room ($168 × 0.67% avg)
+- **2.24x more room for runner to breathe!**
+
+**Volatility adaptation:**
+- Low ATR (0.25%): 0.375% trail = $0.63 @ $168
+- High ATR (0.72%): 0.9% trail cap = $1.51 @ $168 (max cap)
+- Automatically adjusts to market conditions
+
+## Verification Logs
+
+When runner activates, you'll now see:
+```
+🎯 Trailing stop activated at +0.65%
+📊 ATR-based trailing: 0.0045 (0.52%) × 1.5x = 0.78%
+📈 Trailing SL updated: 168.50 → 167.20 (0.78% below peak $168.91)
+```
+
+Instead of:
+```
+⚠️ No ATR data, using fallback: 0.30%
+📈 Trailing SL updated: 168.50 → 168.41 (0.30% below peak $168.91)
+```
+
+## Testing
+
+1. **Existing open trades:** Will use fallback 0.3% (no atrAtEntry yet)
+2. **New trades:** Will capture ATR at entry and use ATR-based trailing
+3. **Settings UI:** Update multiplier at http://localhost:3001/settings
+4. **Log verification:** Check for "📊 ATR-based trailing" messages
+
+## Files Modified
+
+1. ✅ `lib/trading/position-manager.ts` - ATR-based trailing calculation + interface
+2. ✅ `app/settings/page.tsx` - UI for ATR multiplier controls
+3. ✅ `.env.example` - Documentation for new variables
+4. ✅ `config/trading.ts` - Already had the config (wasn't being used!)
+
+## Deployment
+
+```bash
+docker compose build trading-bot
+docker compose up -d --force-recreate trading-bot
+docker logs -f trading-bot-v4
+```
+
+**Status:** ✅ **DEPLOYED AND RUNNING**
+
+## Next Steps
+
+1. **Monitor next runner:** Watch for "📊 ATR-based trailing" in logs
+2. **Compare MFE vs realized P&L:** Should capture 50%+ of MFE (vs current 5-10%)
+3. **Adjust multiplier if needed:** May increase to 2.0x after seeing results
+4. **Update copilot-instructions.md:** Document this fix after validation
+
+## Related Issues
+
+- Fixes the morning's missed opportunity: $172→$162 drop would have been captured
+- Addresses "trades showing +7% MFE but -$2 loss" pattern
+- Makes the 25% runner system actually useful (vs broken 5% system)
+
+## Key Insight
+
+**The config system was already built for this!** The `trailingStopAtrMultiplier` parameter existed in DEFAULT_TRADING_CONFIG and getConfigFromEnv() since the TP2-as-runner redesign. The Position Manager just wasn't using it. This was a "90% done but not wired up" situation.

+  "eventType",
+  message,
+  details,
+  TO_CHAR("createdAt", 'MM-DD HH24:MI:SS') as time

+  COUNT(*) as rate_limit_hits,
+  COUNT(DISTINCT DATE("createdAt")) as days_affected
+FROM "SystemEvent"
+WHERE "eventType" = 'rate_limit_hit'

+  COUNT(CASE WHEN "eventType" = 'rate_limit_hit' THEN 1 END) as total_hits,
+  COUNT(CASE WHEN "eventType" = 'rate_limit_recovered' THEN 1 END) as recovered,
+  COUNT(CASE WHEN "eventType" = 'rate_limit_exhausted' THEN 1 END) as failed,
+  CASE 
+    WHEN COUNT(CASE WHEN "eventType" = 'rate_limit_hit' THEN 1 END) = 0 THEN '✅ HEALTHY'
+    WHEN COUNT(CASE WHEN "eventType" = 'rate_limit_exhausted' THEN 1 END) > 0 THEN '🔴 CRITICAL'
+    WHEN COUNT(CASE WHEN "eventType" = 'rate_limit_hit' THEN 1 END) > 10 THEN '⚠️ WARNING'
+    ELSE '✅ HEALTHY'
+  END as health_status,
+  ROUND(100.0 * COUNT(CASE WHEN "eventType" = 'rate_limit_recovered' THEN 1 END) / 
+        NULLIF(COUNT(CASE WHEN "eventType" = 'rate_limit_hit' THEN 1 END), 0), 1) as recovery_rate

+WHERE "eventType" IN ('rate_limit_hit', 'rate_limit_recovered', 'rate_limit_exhausted')
+  AND "createdAt" > NOW() - INTERVAL '24 hours';
+```
+
+## What to Watch For
+
+### 🔴 Critical Alerts
+- **rate_limit_exhausted** events: Order placement/cancellation failed completely
+- Recovery rate below 80%: System struggling to handle rate limits
+- Multiple exhausted events in short time: RPC endpoint may be degraded
+
+### ⚠️ Warnings
+- More than 10 rate_limit_hit events per hour: High trading frequency
+- Recovery times > 10 seconds: Backoff delays stacking up
+- Rate limits during specific hours: Identify peak Solana network times
+
+### ✅ Healthy Patterns
+- 100% recovery rate: All rate limits handled successfully
+- Recovery times 2-4 seconds: Retries working efficiently
+- Zero rate_limit_exhausted events: No failed operations
+
+## Optimization Actions
+
+**If seeing frequent rate limits:**
+1. Increase `baseDelay` in `retryWithBackoff()` (currently 2000ms)
+2. Add delay between `cancelAllOrders()` and `placeExitOrders()` (currently immediate)
+3. Consider using a faster RPC endpoint (Helius Pro, Triton, etc.)
+4. Batch order operations if possible
+
+**If seeing exhausted retries:**
+1. Increase `maxRetries` from 3 to 5
+2. Increase exponential backoff multiplier (currently 2x)
+3. Check RPC endpoint health/status page
+4. Consider implementing circuit breaker pattern
+
+## Live Monitoring Commands
+
+```bash
+# Watch rate limits in real-time
+docker logs -f trading-bot-v4 | grep -i "rate limit"
+
+# Count rate limit events today
+docker exec trading-bot-postgres psql -U postgres -d trading_bot_v4 -c "
+SELECT COUNT(*) FROM \"SystemEvent\" 
+WHERE \"eventType\" = 'rate_limit_hit' 
+AND DATE(\"createdAt\") = CURRENT_DATE;"
+
+# Check latest rate limit event
+docker exec trading-bot-postgres psql -U postgres -d trading_bot_v4 -c "
+SELECT * FROM \"SystemEvent\" 
+WHERE \"eventType\" IN ('rate_limit_hit', 'rate_limit_recovered', 'rate_limit_exhausted') 
+ORDER BY \"createdAt\" DESC LIMIT 1;"
+```
+
+## Integration with Alerts
+
+When implementing automated alerts, trigger on:
+- Any `rate_limit_exhausted` event (critical)
+- More than 5 `rate_limit_hit` events in 5 minutes (warning)
+- Recovery rate below 90% over 1 hour (warning)
+
+Log format examples:
+```
+✅ Retry successful after 2341ms (1 retries)
+⏳ Rate limited (429), retrying in 2s... (attempt 1/3)
+❌ RATE LIMIT EXHAUSTED: Failed after 3 retries and 14523ms
+```
