mindesbunister e8a9b68fa7 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'

**Documentation:**
- Created CRITICAL_ISSUES_FOUND.md explaining all 3 issues
- Created FIXES_APPLIED.md with testing instructions

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:

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


Fix 1: TradingView Alert Format

Update your TradingView alert to include ".P 15":

{{ticker}} {{strategy.order.action}} .P 15
