## 🔧 Key Improvements
|
||||
|
||||
### 1. Parameter Validation
|
||||
```mql5
|
||||
if(chart_id == 0)
|
||||
{
|
||||
Print("[ERROR] Invalid chart ID: 0");
|
||||
}
|
||||
```
|
||||
|
||||
### 2. UI Element Validation
|
||||
```mql5
|
||||
if(!ObjectCreate(m_chart_id, "AccumLossLabel", OBJ_LABEL, 0, 0, 0))
|
||||
{
|
||||
Print("[ERROR] Failed to create AccumLossLabel. Error: ", GetLastError());
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Debug Logging
|
||||
```mql5
|
||||
[UIManager] Creating UI elements...
|
||||
[UIManager] Creating loss display labels...
|
||||
[UIManager] Loss display labels created
|
||||
[UIManager] UI elements created successfully
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 📝 Logging Examples
|
||||
|
||||

|
||||
Symbol: XAUUSD
|
||||
High loss threshold: 0%
|
||||
```
|
||||
|
||||
### UI Creation
|
||||
```

|
||||
```
|
||||
|
||||
### Error Handling

|
||||
[ERROR] Invalid magic number: 0. Using default 24680
|
||||

|
||||
## 💡 Notes
|
||||
|
||||
1. **Debug Mode**: Controlled by `EnableDebugPrints` input parameter
|
||||
2. **UI Elements**: Created on chart, deleted on deinitialization
|
||||
3. **Validation**: All parameters validated before use
|
||||
4. **Error Codes**: All errors include error code and description
|
||||
5. **Logging Format**: Consistent `[UIManager]` prefix for easy filtering

## 🔧 Usage Examples
|
||||
|
||||
### Basic Usage
|
||||
```mql5
|
||||
// Update loss display
|
||||
g_ui_manager.UpdateLossDisplay(accumulated_loss, loss_percent);
|
||||
|
||||
// Get manual TP/SL
|
||||
double manual_tp = g_ui_manager.GetManualTP();
|
||||
double manual_sl = g_ui_manager.GetManualSL();
|
||||
```
|
||||
|
||||
### Debug Mode
|
||||
```mql5
|
||||
// Enable debug logging
|
||||
g_ui_manager.SetDebugMode(true);
|
||||
|
||||
// Update display (will log details)
|
||||
g_ui_manager.UpdateLossDisplay(accumulated_loss, loss_percent);
|
||||
