🔧 Key Improvements

1. Parameter Validation

if(chart_id == 0)
{
    Print("[ERROR] Invalid chart ID: 0");
}

2. UI Element Validation

if(!ObjectCreate(m_chart_id, "AccumLossLabel", OBJ_LABEL, 0, 0, 0))
{
    Print("[ERROR] Failed to create AccumLossLabel. Error: ", GetLastError());
}

3. Debug Logging

[UIManager] Creating UI elements...
[UIManager] Creating loss display labels...
[UIManager] Loss display labels created
[UIManager] UI elements created successfully

📝 Logging Examples

Initialization

[UIManager] Parameters set:
  Chart ID: 1319423456789
  Manual mode: false
  Magic number: 24680
  Symbol: XAUUSD
  High loss threshold: 0%

UI Creation

[UIManager] Creating UI elements...
[UIManager] Creating loss display labels...
[UIManager] Loss display labels created
[UIManager] UI elements created successfully

Loss Display Update

[UIManager] Loss display updated: Accum. Loss: 150.00, Loss % of Bal: 1.50%

High Loss Warning

[UIManager] Loss display updated: Accum. Loss: 500.00, Loss % of Bal: 5.00% [HIGH LOSS WARNING]

Error Handling

[ERROR] Invalid chart ID: 0
[ERROR] Invalid magic number: 0. Using default 24680
[ERROR] Failed to create AccumLossLabel. Error: Object not found (Code: 4202)

🐛 Edge Cases Handled

1. ✅ Invalid chart ID (0)
2. ✅ Invalid magic number (<= 0)
3. ✅ Empty symbol
4. ✅ Invalid high loss threshold (< 0)
5. ✅ Invalid accumulated loss (< 0)
6. ✅ Invalid loss percent (< 0)
7. ✅ UI element creation failure
8. ✅ UI element deletion failure
9. ✅ Manual mode not enabled
10. ✅ Object not found errors

📋 UI Elements

Loss Display Labels (Bottom-Left)

• AccumLossLabel: Shows accumulated loss amount
• AccumLossPercentLabel: Shows loss as % of balance
• Color: White (normal), OrangeRed (high loss warning)

Manual Mode Controls (Top-Right)

• ManualTPLabel: "Take Profit:" label
• ManualTPEdit: TP input field (60px wide)
• ManualSLLabel: "Stop Loss:" label
• ManualSLEdit: SL input field (60px wide)
• ManualTradeButton: "Open Market Order" button (130x25px)

🚀 Next Steps: Phase 10

What's Next?

Phase 10 will implement Integration functionality:

1. ✅ Final integration testing
2. ✅ Component interaction verification
3. ✅ End-to-end flow testing
4. ✅ Error handling verification
5. ✅ Performance optimization
6. ✅ Code review and cleanup

Estimated time: ~20-30 minutes

---

📋 Testing Checklist

Before moving to Phase 10, verify:

• UIManager compiles without errors
• Debug mode works correctly
• Parameter validation works
• UI elements create correctly
• Loss display updates correctly
• Manual mode controls work
• All edge cases are covered

---

💡 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

// 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

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

// Update display (will log details)
g_ui_manager.UpdateLossDisplay(accumulated_loss, loss_percent);
