|
||||
## 🔧 Key Improvements
|
||||
|
||||
### 1. TP Tracking System
|
||||
```
|
||||
Tracks which TP levels have been closed for each ticket
|
||||
Prevents duplicate partial closes
|
||||
Updates tracking after each successful close
|
||||
```
|
||||
|
||||
### 2. Comment Update Logic
|
||||
```
|
||||
TP1 Closed → Update BE flag to 1
|
||||
All TPs Closed → Update TS flag to ACTIVE
|
||||
```
|
||||
|
||||
### 3. Debug Logging
|
||||
```mql5
|
||||
[PartialCloseManager] Checking position #12345 (1.0 lots)
|
||||
[PartialCloseManager] Found 3 TP levels for ticket #12345
|
||||
[PartialCloseManager] TP1 reached for ticket #12345
|
||||
Close lots: 0.33 (33.3%)
|
||||
[PartialCloseManager] Partial close executed: 0.33 lots at TP1
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 📝 Logging Examples
|
||||
|
||||
### Initialization
|
||||
```
|
||||
[PartialCloseManager] Parameters set:
|
||||
Enable partial close: true
|
||||
Use equal division: true
|
||||
Partial close percentages: 3 levels
|
||||
```
|
||||
|
||||
### Position Check
|
||||
```
|
||||
[PartialCloseManager] Checking position #12345 (1.0 lots)
|
||||
[PartialCloseManager] Found 3 TP levels for ticket #12345
|
||||
```
|
||||
|
||||
### TP Reached
|
||||
```
|
||||
[PartialCloseManager] TP1 reached for ticket #12345
|
||||
Close lots: 0.33 (33.3%)
|
||||
[PartialCloseManager] Partial close executed: 0.33 lots at TP1 for ticket #12345
|
||||
[PartialCloseManager] Comment updated for ticket #12345
|
||||
```
|
||||
|
||||
### Error Handling
|
||||
```
|
||||
[ERROR] Invalid close lots: 0.0 for ticket #12345
|
||||
[ERROR] Failed to execute partial close for ticket #12345. Error: Invalid volume
|
||||
[WARNING] Close lots (0.5) > current lots (0.3) for ticket #12345. Adjusting to current lots.
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🐛 Edge Cases Handled
|
||||
|
||||
1. ✅ Invalid partial close percentages (<= 0 or > 100%)
|
||||
2. ✅ Percentages don't sum to 100%
|
||||
3. ✅ Close lots > current lots
|
||||
4. ✅ Close lots <= 0
|
||||
5. ✅ Position not found
|
||||
6. ✅ No TPs in comment
|
||||
7. ✅ Duplicate TP closes (prevented by tracking)
|
||||
8. ✅ Order modification failure
|
||||
9. ✅ TP tracking overflow
|
||||
10. ✅ Comment update failure

|

|
||||
## 📋 Partial Close Logic
|
||||
|
||||
### Equal Division Mode
|
||||
```
|
||||
Total Lots: 1.0
|
||||
TP Count: 3
|
||||
|
||||
TP1: Close 0.33 lots (33.3%)
|
||||
TP2: Close 0.33 lots (33.3%)
|
||||
TP3: Close 0.34 lots (33.4%)
|
||||
```
|
||||
|
||||
### Custom Percentage Mode
|
||||
```
|
||||
Total Lots: 1.0
|
||||
TP1_ClosePercent: 50%
|
||||
TP2_ClosePercent: 30%
|
||||
TP3_ClosePercent: 20%
|
||||
|
||||
TP1: Close 0.50 lots (50%)
|
||||
TP2: Close 0.30 lots (30%)
|
||||
TP3: Close 0.20 lots (20%)
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 📋 TP Tracking System
|
||||
|
||||
### Tracking Structure
|
||||
```mql5
|
||||
struct TPTracking
|
||||
{
|
||||
ulong ticket; // Position ticket
|
||||
int last_closed_tp; // Last TP level closed
|
||||
datetime last_check_time; // Last check timestamp
|
||||
};
|
||||
```
|
||||
|
||||
### Tracking Logic
|
||||
1. Check if ticket exists in tracking
|
||||
2. If yes, get last closed TP level
|
||||
3. Only check TPs after last closed level
|
||||
4. Update tracking after successful close
|
||||
5. Clear tracking when position closes
|
||||

||||
|
||||
## 🚀 Next Steps: Phase 7
|
||||
|
||||
### What's Next?
|
||||
Phase 7 will implement **Trade Executor** functionality:
|
||||
|
||||
1. ✅ Enhanced order execution
|
||||
2. ✅ Multiple TP comment handling
|
||||
3. ✅ Screenshot improvements
|
||||
4. ✅ Error handling
|
||||
5. ✅ Integration with main EA
|
||||
6. ✅ Testing trade execution logic
|
||||
|
||||
**Estimated time:** ~20-25 minutes
|
||||

|
||||
|
||||
## 📋 Testing Checklist
|
||||
|
||||
Before moving to Phase 7, verify:
|
||||
|
||||
- [ ] PartialCloseManager compiles without errors
|
||||
- [ ] Debug mode works correctly
|
||||
- [ ] Parameter validation works
|
||||
- [ ] TP tracking prevents duplicate closes
|
||||
- [ ] Comment updates correctly
|
||||
- [ ] Partial close executes correctly
|
||||
- [ ] All edge cases are covered
|
||||
|
||||

|
||||
|
||||
## 💡 Notes
|
||||
|
||||
1. **Debug Mode**: Controlled by `EnableDebugPrints` input parameter
|
||||
2. **TP Tracking**: Prevents duplicate partial closes
|
||||
3. **Comment Updates**: Updates BE and TS flags after partial closes
|
||||
4. **Validation**: All parameters validated before use
|
||||
5. **Logging Format**: Consistent `[PartialCloseManager]` prefix for easy filtering

## 🔧 Usage Examples
|
||||
|
||||
### Basic Usage
|
||||

||||
// Check and execute partial closes
|
||||
g_partial_close_manager.CheckAndExecutePartialCloses();
|
||||
```
|
||||
|
||||
### Debug Mode
|
||||
```mql5
|
||||
// Enable debug logging
|
||||
g_partial_close_manager.SetDebugMode(true);
|
||||
|
||||
// Check partial closes (will log details)
|
||||
g_partial_close_manager.CheckAndExecutePartialCloses();
|
||||
```
|
||||
|
||||
### Manual TP Tracking
|
||||
```mql5
|
||||
// Clear tracking for specific ticket
