🔧 CRITICAL FIX v1.2.9 - OCO Quantity Precision

🚨 Critical OCO Order Failure Fixed

OCO orders were completely broken for symbols requiring specific quantity precision, causing loss of stop-loss protection.

🐛 The Problem

❌ API Error: Parameter 'quantity' has too much precision (-1111)
📊 Example: 40.90000000 ADA → Rejected (needs 40.90)
🛡️ Result: No OCO orders, no stop-loss protection
⚠️ Fallback: LIMIT orders only (risky)

Real user log example:

🏪 Quantité à vendre: 40.90000000 (96.5%)  ❌
❌ Erreur API Binance [-1111]: Parameter 'quantity' has too much precision
⚠️ Échec ordre OCO, fallback vers ordre limite

📊 Affected Symbols & Impact

Symbol Required Precision Sent Before Sent After OCO Status
ADA 2 decimals 40.90000000 ❌ 40.90 ✅ Fixed
DOGE Variable X.XXXXXXXX ❌ X.XX ✅ Fixed
All Per LOT_SIZE 8 decimals ❌ Correct ✅ Fixed

🔧 Technical Root Cause

Incomplete quantity formatting:

# ❌ BEFORE (insufficient)
sell_quantity = round(sell_quantity / step_size) * step_size
# Result: 40.90000000 (aligned but wrong precision)

# ✅ AFTER (complete)
qty_precision = max(0, -int(log10(step_size)))
sell_quantity = round(sell_quantity / step_size) * step_size
sell_quantity = round(sell_quantity, qty_precision)
# Result: 40.90 (aligned AND correct precision)

🛡️ Security & Risk Impact

🚨 Before Fix (Broken Protection)

  • OCO orders: Failed on precision-sensitive symbols
  • Stop-loss: Not available (LIMIT fallback only)
  • Risk exposure: No downside protection
  • Portfolio protection: Compromised

✅ After Fix (Full Protection)

  • OCO orders: Work on ALL symbols
  • Stop-loss: Available for all trades
  • Risk management: Fully functional
  • Portfolio protection: Complete

🎯 Real User Benefits

🔴 ADA Trade:
   💰 Buy: 42.40 ADA ✅
   🛡️ OCO: FAILED ❌
   📊 Protection: None (LIMIT only)
   🚨 Risk: Full downside exposure

   🛡️ OCO: 40.90 ADA ✅ (correct precision)
   📊 Protection: +3.5% profit / -8% stop-loss
   ✅ Risk: Fully protected

🔍 How to Verify Fix

After updating to v1.2.9, look for:

🔧 Quantité formatée: 40.90 (précision: 2)  ← New debug info
✅ ORDRE OCO PLACÉ ADAUSDC                   ← Success instead of error
   🎯 Profit: 0.9286 (+3.5%)
   🛡️ Stop-Loss: 0.8244 (-8.0%)

Instead of:

❌ Erreur API Binance [-1111]: Parameter 'quantity' has too much precision
⚠️ Échec ordre OCO, fallback vers ordre limite
