|
## 🔧 Key Improvements
|
|
|
|
### 1. Parameter Validation
|
|
```mql5
|
|
if(slippage_points < 0)
|
|
{
|
|
Print("[ERROR] Invalid slippage points: ", slippage_points, ". Using default 30");
|
|
m_slippage_points = 30;
|
|
}
|
|
```
|
|
|
|
### 2. Debug Logging
|
|
```mql5
|
|
[TradeExecutor] Executing trade...
|
|
Direction: BUY
|
|
Lots: 0.03
|
|
SL: 1.2480

|
|
Comment: UnivBufEA_24680;TP1=1.2530;TP2=1.2560;TP3=1.2600;BE=0;TS=0
|
|
Execution price: 1.2500
|
|
```
|
|
|
|
### 3. Error Handling
|
|
```mql5
|
|
[ERROR] Invalid lots: 0.00
|
|
[ERROR] OrderSend failed: Invalid volume (Code: 4756)
|
|
[ERROR] Failed to save screenshot. Error: File not found (Code: 5004)

|
|
|
### What's Next?
|
|
Phase 8 will implement **State Manager** functionality:
|
|
|
|
1. ✅ Enhanced state persistence
|
|
2. ✅ Global variable management
|
|
3. ✅ Error handling
|
|
4. ✅ Debug logging
|
|
5. ✅ Integration with main EA
|
|
6. ✅ Testing state management logic

## 💡 Notes
|
|
|
|
1. **Debug Mode**: Controlled by `EnableDebugPrints` input parameter
|
|
2. **Error Codes**: All errors include error code and description
|
|
3. **Validation**: All inputs validated before execution
|
|
4. **Logging Format**: Consistent `[TradeExecutor]` prefix for easy filtering
|
|
5. **Screenshot**: Only taken if `TakeScreenshotOnOpen = true`

## 🔧 Usage Examples
|
|
|
|
### Basic Usage
|
|
```mql5
|
|
// 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
|
|
```mql5
|
|
// Enable debug logging
|
|
g_trade_executor.SetDebugMode(true);
|
|
|
|
// Execute trade (will log details)
|
|
CTradeExecutor::TradeResult result = g_trade_executor.ExecuteTrade(...);
|
|
```
|
|
|
|
### Check Trade Status
|
|
```mql5
|
|
// Check if trade is open
|
|
if(g_trade_executor.IsTradeOpen())
|
|
{
|
|
Print("Trade is already open");
|
|
}
|
|
```
