- ✅ Enhanced SL/TP validation
- ✅ TP parsing from order comments
- ✅ Edge case handling

#### Specific Improvements

##### Constructor
- Added `m_enable_debug` flag for debug logging

##### SetParameters()
- ✅ Parameter validation (trailing pips, breakeven pips)
- ✅ Value validation (pip value, digits, stop level)
- ✅ Default values for invalid parameters
- ✅ Parameter logging when debug enabled
- ✅ Added `SetDebugMode()` method

##### ManageRiskManagement()

- [x] Standard trailing stop implementation
- [x] Enhanced SL/TP validation
- [x] Debug logging
- [x] Edge case handling
- [x] TP parsing from comments

## 🔧 Key Improvements

### 1. TP-Based Trailing Logic
```
TP1 Reached → SL moves to Breakeven (Open Price)
TP2 Reached → SL moves to TP1
TP3 Reached → SL moves to TP2
After TP3 → Standard trailing activates
```

### 2. Standard Trailing Logic
```
SL = Current Price ± Trailing Distance
Ratchet Rule: SL only moves in profit direction
```

### 3. Debug Logging
```mql5
[RiskManager] Checking position #12345
  Type: BUY
  Open: 1.2500, Current: 1.2530, SL: 1.2480
[RiskManager] TP1 reached for ticket #12345
[RiskManager] SL moved for ticket #12345 to 1.2500 (TP1)
```

---

## 📝 Logging Examples

### Initialization
```
[RiskManager] Parameters set:
  Use trailing stop: true (300 pips)
  Use breakeven: true (30 pips)
  Pip value: 0.0001, Digits: 5
  Stop level: 30 points
```

### Position Check
```
[RiskManager] Checking position #12345
  Type: BUY
  Open: 1.2500, Current: 1.2530, SL: 1.2480
```

### Breakeven Activation
```
[RiskManager] Breakeven set for ticket #12345 at 1.2500
```

### TP-Based Trailing
```
[RiskManager] TP1 reached for ticket #12345
[RiskManager] SL moved for ticket #12345 to 1.2500 (TP1)
```

### Standard Trailing
```
[RiskManager] Trailing SL for ticket #12345
  Current SL: 1.2500, New SL: 1.2520
[RiskManager] SL moved for ticket #12345 to 1.2520 (TRAIL)
```

### Error Handling
```
[ERROR] Invalid trailing stop pips: 0. Using default 300
[ERROR] Invalid breakeven pips: 0. Using default 30
[ERROR] Failed to set breakeven for ticket #12345. Error: Invalid stops
```

---

## 🐛 Edge Cases Handled

1. ✅ Invalid trailing stop pips (<= 0)
2. ✅ Invalid breakeven pips (<= 0)
3. ✅ Invalid pip value (<= 0)
4. ✅ Invalid digits (<= 0)
5. ✅ Invalid stop level (< 0)
6. ✅ SL already at breakeven
7. ✅ SL already at target level
8. ✅ No TPs in comment
9. ✅ TP values = 0
10. ✅ Position not found
11. ✅ Order modification failure

## 📋 Risk Management Logic

### Breakeven
```
Condition: Profit >= Breakeven Pips
Action: Move SL to Open Price
```

### TP-Based Trailing
```
TP1 Reached: SL → Open Price (Breakeven)
TP2 Reached: SL → TP1
TP3 Reached: SL → TP2
```

### Standard Trailing
```
Condition: Price moves in favor
Action: SL = Price ± Trailing Distance
Rule: SL only moves in profit direction (ratchet)
```

---

## 📋 Order Comment Format

```
UnivBufEA_24680_H1;TP1=1.2530;TP2=1.2560;TP3=1.2600;BE=0;TS=0
```

### Comment Flags
- `TP1`, `TP2`, `TP3`: Take profit levels
- `BE=0`: Breakeven not yet activated
- `BE=1`: Breakeven activated
- `TS=0`: Trailing not active
- `TS=ACTIVE`: Trailing active

## 🚀 Next Steps: Phase 6

### What's Next?
Phase 6 will implement **Partial Close Manager** functionality:

1. ✅ Enhanced partial close logic
2. ✅ TP detection improvements
3. ✅ Comment update after partial close
4. ✅ Integration with main EA
5. ✅ Testing partial close logic

**Estimated time:** ~20-25 minutes

---

## 📋 Testing Checklist

Before moving to Phase 6, verify:

- [ ] RiskManager compiles without errors
- [ ] Debug mode works correctly
- [ ] Breakeven activates at correct level
- [ ] TP-based trailing works correctly
- [ ] Standard trailing works correctly
- [ ] TP parsing from comments works
- [ ] All edge cases are covered

---

## 💡 Notes

1. **Debug Mode**: Controlled by `EnableDebugPrints` input parameter
2. **TP-Based Trailing**: Only active when partial close is enabled
3. **Ratchet Rule**: SL only moves in profit direction
4. **Comment Parsing**: TPs extracted from order comment
5. **Logging Format**: Consistent `[RiskManager]` prefix for easy filtering

---

## 🔧 Usage Examples

### Basic Usage
```mql5
// Manage risk for all positions
g_risk_manager.ManageRiskManagement();
```

### Debug Mode
```mql5
// Enable debug logging
g_risk_manager.SetDebugMode(true);

// Manage risk (will log details)
g_risk_manager.ManageRiskManagement();
```

### Manual SL Move
```mql5
// Move SL to specific level
g_risk_manager.TryMoveSL(ticket, new_sl, "MANUAL");
```

**Phase 5 Status: ✅ COMPLETE**
