- [x] Better validation of time parameters
- [x] Comprehensive logging integration
- [x] Helper methods for time information
- [x] Edge case handling

---

## 🔧 Key Improvements

### 1. Debug Logging
```mql5
// Before
// No logging

// After
if(m_enable_debug)
{
    Print("[TimeFilter] Time check - Day allowed: ", day_allowed,
          ", Session allowed: ", session_allowed,
          ", Result: ", (result ? "ALLOWED" : "BLOCKED"));
}
```

### 2. Detailed Session Information
```mql5
// Before
if(IsAsianSession(hour) && m_asian_enabled) return true;

// After
bool in_asian = IsAsianSession(hour);
bool in_europe = IsEuropeSession(hour);
bool in_america = IsAmericaSession(hour);

if(m_enable_debug)
{
    Print("[TimeFilter] In Asian session (00-08): ", in_asian, " - Enabled: ", m_asian_enabled);
    Print("[TimeFilter] In Europe session (07-16): ", in_europe, " - Enabled: ", m_europe_enabled);
    Print("[TimeFilter] In America session (13-22): ", in_america, " - Enabled: ", m_america_enabled);
}
```

### 3. Helper Methods
```mql5
// Get current time information
string day = g_time_filter.GetCurrentDayOfWeek();      // "Monday"
string session = g_time_filter.GetCurrentSession();    // "Europe"
string time = g_time_filter.GetCurrentGMTTime();       // "14:30:45 GMT"
```

## 📝 Logging Examples

### Initialization
```
[TimeFilter] Parameters set - Enabled: true
[TimeFilter] Days: Mon=true Tue=true Wed=true Thu=true Fri=true Sat=false Sun=false
[TimeFilter] Sessions: Asian=true Europe=true America=true
```

### Time Check (Debug Mode)
```
[TimeFilter] Day of week: Monday (1) - ALLOWED
[TimeFilter] Current time: 14:00 GMT
[TimeFilter] In Asian session (00-08): false - Enabled: true
[TimeFilter] In Europe session (07-16): true - Enabled: true
[TimeFilter] In America session (13-22): true - Enabled: true
[TimeFilter] Active session: Europe - ALLOWED
[TimeFilter] Time check - Day allowed: true, Session allowed: true, Result: ALLOWED
```

### Time Filter Disabled
```
[TimeFilter] Time filtering disabled - Trading allowed
```

### Time Filter Blocked
```
[TimeFilter] Day of week: Saturday (6) - BLOCKED
[TimeFilter] Current time: 10:00 GMT
[TimeFilter] In Asian session (00-08): false - Enabled: true
[TimeFilter] In Europe session (07-16): true - Enabled: true
[TimeFilter] In America session (13-22): false - Enabled: true
[TimeFilter] Active session: Europe - ALLOWED
[TimeFilter] Time check - Day allowed: false, Session allowed: true, Result: BLOCKED
```

### Session Blocked
```
[TimeFilter] Day of week: Monday (1) - ALLOWED
[TimeFilter] Current time: 23:00 GMT
[TimeFilter] In Asian session (00-08): false - Enabled: true
[TimeFilter] In Europe session (07-16): false - Enabled: true
[TimeFilter] In America session (13-22): false - Enabled: true
[TimeFilter] Active session: None - BLOCKED
[TimeFilter] Time check - Day allowed: true, Session allowed: false, Result: BLOCKED
```

## 🐛 Edge Cases Handled

1. ✅ Time filter disabled
2. ✅ All days disabled
3. ✅ All sessions disabled
4. ✅ Overlapping sessions
5. ✅ Off-hours trading
6. ✅ Weekend trading
7. ✅ Session boundaries
8. ✅ Day boundaries

---

## 📋 Session Definitions

| Session | GMT Hours | Description |
|---------|-----------|-------------|
| Asian | 00:00 - 08:00 | Tokyo, Sydney, Singapore |
| Europe | 07:00 - 16:00 | London, Frankfurt, Paris |
| America | 13:00 - 22:00 | New York, Chicago, Toronto |

**Note**: Sessions overlap:
- Asian/Europe overlap: 07:00 - 08:00 GMT
- Europe/America overlap: 13:00 - 16:00 GMT

## 🚀 Next Steps: Phase 4

### What's Next?
Phase 4 will implement **Money Management** functionality:

1. ✅ Enhanced lot size calculation
2. ✅ Daily profit tracking improvements
3. ✅ Validation of lot parameters
4. ✅ Integration with main EA
5. ✅ Testing money management logic

**Estimated time:** ~15-20 minutes

## 📋 Testing Checklist

Before moving to Phase 4, verify:

- [ ] TimeFilter compiles without errors
- [ ] Debug mode works correctly
- [ ] Time filtering works as expected
- [ ] Day filtering works correctly
- [ ] Session filtering works correctly
- [ ] Helper methods return correct values
- [ ] All edge cases are covered

---

## 💡 Notes

1. **Debug Mode**: Controlled by `EnableDebugPrints` input parameter
2. **Time Zone**: All times are in GMT
3. **Session Overlap**: Multiple sessions can be active simultaneously
4. **Logging Format**: Consistent `[TimeFilter]` prefix for easy filtering
5. **Helper Methods**: Useful for UI display and debugging

## 🔧 Usage Examples

### Basic Usage
```mql5
// Check if trading is allowed
if(g_time_filter.IsTimeAllowed())
{
    // Execute trade
}
else
{
    Print("Trading not allowed at this time");
}
```

### Get Time Information
```mql5
// Display current time info
Print("Current day: ", g_time_filter.GetCurrentDayOfWeek());
Print("Current session: ", g_time_filter.GetCurrentSession());
Print("Current time: ", g_time_filter.GetCurrentGMTTime());
```

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

// Check time (will log details)
bool allowed = g_time_filter.IsTimeAllowed();
```
