🔧 Key Improvements

1. Parameter Validation

if(slippage_points < 0)
{
    Print("[ERROR] Invalid slippage points: ", slippage_points, ". Using default 30");
    m_slippage_points = 30;
}

2. Debug Logging

🚀 Next Steps: Phase 8

What's Next?

Phase 8 will implement State Manager functionality:

✅ Enhanced state persistence
✅ Global variable management
✅ Error handling
✅ Debug logging
✅ Integration with main EA
✅ Testing state management logic

Estimated time: ~15-20 minutes

📋 Testing Checklist

Before moving to Phase 8, verify:

TradeExecutor compiles without errors
Debug mode works correctly
Parameter validation works
Order execution works correctly
Partial close works correctly
Screenshot functionality works
All edge cases are covered

💡 Notes

Debug Mode: Controlled by EnableDebugPrints input parameter
Error Codes: All errors include error code and description
Validation: All inputs validated before execution
Logging Format: Consistent [TradeExecutor] prefix for easy filtering
Screenshot: Only taken if TakeScreenshotOnOpen = true

🔧 Usage Examples

Basic Usage

// Execute trade
CTradeExecutor::TradeResult result = g_trade_executor.ExecuteTrade(
    true,           // is_buy
    0.03,           // lots
    1.2500,         // open_price
    1.2480,         // sl_price
    tp_prices,      // tp_prices array
    3               // tp_count
);

Debug Mode

// Enable debug logging
g_trade_executor.SetDebugMode(true);

// Execute trade (will log details)
CTradeExecutor::TradeResult result = g_trade_executor.ExecuteTrade(...);

Check Trade Status

// Check if trade is open
if(g_trade_executor.IsTradeOpen())
{
    Print("Trade is already open");
}

Phase 7 Status: ✅ COMPLETE

Ready to proceed with Phase 8: State Manager Implementation
