Fix: Critical bugs - TP2 runner calculation + race condition + order cleanup

**Issue 1: TP2 Runner Position Bug** ✅ FIXED
- TP2 was calculated as 80% of ORIGINAL position instead of REMAINING
- With TP1=75%, TP2=80%: Was closing 75%+80%=155% (capped at 100%)
- Now correctly: TP1 closes 75%, TP2 closes 80% of remaining 25% = 20%
- Result: 5% runner now remains for trailing stop as intended!

**Issue 2: Race Condition - Orphaned SL Orders** ✅ FIXED
- Orders were placed AFTER Position Manager started monitoring
- If TP hit fast, PM detected 'external closure' before orders finished
- Orders completed after position gone → orphaned SL orders on Drift
- Now: Exit orders placed BEFORE starting monitoring
- PM can now properly cancel remaining orders when position closes

**Issue 3: 5min vs 15min Timeframe** ⚠️ NEEDS VERIFICATION
- n8n workflow correctly filters for timeframe === '15'
- Extracts timeframe with regex: /\.P\s+(\d+)/
- User needs to verify TradingView alert includes '.P 15' in message
- Format should be: 'SOL buy .P 15' not just 'SOL buy'

**Technical Changes:**
- lib/drift/orders.ts: Fixed TP2 calculation to use remaining size
- Added logging: Shows TP1, TP2, remaining, and runner amounts
- app/api/trading/execute/route.ts: Reordered to place orders before monitoring
- Prevents race condition where orders complete after position closed

**Testing:**
- Next trade will show proper runner position (5% remains)
- No more orphaned SL orders after wins
- Logs will show: 'Runner (if any): $X.XX'

- Created CRITICAL_ISSUES_FOUND.md explaining all 3 issues

+# Trading Bot v4 - Critical Issues Found & Fixes
+
+## Issue Summary
+
+Three critical issues discovered:
+
+1. **5-minute chart triggered instead of 15-minute** - TradingView alert format issue
+2. **SL orders not cancelled after winning trade** - Race condition + order calculation bug
+3. **No runner position (20% should remain)** - TP2 size calculation bug
+
+---
+
+## Issue 1: Wrong Timeframe Triggered
+
+### Problem
+- Trade executed on 5-minute chart signal
+- n8n workflow has correct filter for "15" timeframe
+- Filter checks: `timeframe === "15"`
+
+### Root Cause
+- n8n extracts timeframe with regex: `/\.P\s+(\d+)/`
+- Looks for ".P 5" or ".P 15" in TradingView message
+- Defaults to '15' if no match found
+
+### Solution
+**Check your TradingView alert message format:**
+
+Your alert should include the timeframe like this:
+```
+SOL buy .P 15
+```
+
+The ".P 15" tells n8n it's a 15-minute chart. If you're sending:
+```
+SOL buy .P 5
+```
+
+Then n8n will reject it (correctly filtering out 5-minute signals).
+
+**Verify n8n is receiving correct format by checking n8n execution logs.**

+
+## Issue 2: SL Orders Not Cancelled
+
+### Problem
+- After winning trade, 2 SL orders remain on Drift ($198.39 and $195.77)
+- Bot detected "position closed externally" but found "no orders to cancel"
+
+### Root Cause
+**Race Condition in `/api/trading/execute`:**
+
+Current order of operations:
+1. Open position ✅
+2. Add to Position Manager (starts monitoring immediately) ⚠️
+3. Place exit orders (TP1, TP2, SL) ⏰
+
+If TP hits very fast (< 2-3 seconds):
+- Position Manager detects "external closure" while orders are still being placed
+- Tries to cancel orders that don't exist yet
+- Orders finish placing AFTER position is gone → orphaned orders
+
+### Solution
+**Reorder operations: Place exit orders BEFORE starting monitoring**
+
+---
+
+## Issue 3: No Runner Position
+
+### Problem
+- Config: `TAKE_PROFIT_2_SIZE_PERCENT=80` (should leave 20% runner)
+- Expected: TP1 closes 75% → TP2 closes 80% of remaining → 5% runner remains
+- Actual: Position 100% closed, no runner
+
+### Root Cause
+**BUG in `/home/icke/traderv4/lib/drift/orders.ts` lines 232-233:**
+
+```typescript
+const tp1USD = (options.positionSizeUSD * options.tp1SizePercent) / 100
+const tp2USD = (options.positionSizeUSD * options.tp2SizePercent) / 100
+```
+
+Both TP1 and TP2 are calculated as **percentages of ORIGINAL position**, not remaining!
+
+**With your settings (TP1=75%, TP2=80%, position=$80):**
+- TP1: 75% × $80 = $60 ✅
+- TP2: 80% × $80 = $64 ❌ (should be 80% × $20 remaining = $16)
+- Total: $60 + $64 = $124 (exceeds position size!)
+
+Drift caps at 100%, so entire position closes.
+
+### Solution
+**Fix TP2 calculation to use remaining size after TP1**
+
+---
+
+## Recommended Fixes
+
+### Fix 1: TradingView Alert Format
+
+Update your TradingView alert to include ".P 15":
+```
+{{ticker}} {{strategy.order.action}} .P 15
+```
+
+### Fix 2 & 3: Code Changes
