## Usage Recommendations

### For Conservative Trading
```
Inp_Risk_MaxDailyLoss = 5.0        // 5% max daily loss
Inp_Risk_MaxDailyProfit = 10.0     // 10% profit target
Inp_Risk_MaxTradesPerDay = 5      // Max 5 trades per day
Inp_Risk_EnableTimeFilter = true   // Enable time filter
Inp_Log_Level = 1                  // Info level logging
```

### For Aggressive Trading
```
Inp_Risk_MaxDailyLoss = 0.0        // No daily loss limit
Inp_Risk_MaxDailyProfit = 0.0      // No profit limit
Inp_Risk_MaxTradesPerDay = 0       // Unlimited trades
Inp_Risk_EnableTimeFilter = false  // Trade 24/7
Inp_Log_Level = 2                  // Debug logging
```

### For Testing
```
Expert_EnableTrading = false        // Disable actual trading
Inp_Log_Level = 2                  // Full debug logging
Expert_ShowAlerts = true           // Show all alerts
```

## Comparison: Original vs Improved

| Feature | Original | Improved |
|---------|----------|----------|
| Input Organization | Basic | Grouped by category |
| Risk Management | None | Daily limits, time filter |
| Logging | Basic Print | Multi-level logging system |
| Error Handling | Basic | Comprehensive |
| Statistics | None | Daily & account tracking |
| Safety Checks | Minimal | Multiple validation layers |
| Trading Control | Limited | Master switch + filters |
| Code Documentation | Minimal | Well documented |

## Migration Guide

### From Original to Improved

1. **Copy the improved EA** to your MT5 Experts folder
2. **Compile** in MetaEditor (F7)
3. **Configure parameters**:
   - Set your preferred risk management limits
   - Configure logging level
   - Set time filters if needed
4. **Test on demo account** first
5. **Monitor logs** to verify behavior

### Parameter Mapping

Most original parameters remain the same:
- `Inp_Signal_MA_Period` → Same
- `Inp_Trailing_ParabolicSAR_Step` → Same
- `Inp_Money_SizeOptimized_Percent` → Same

New parameters have defaults that maintain original behavior:
- Risk limits default to 0 (disabled)
- Time filter defaults to disabled
- Logging defaults to Info level

## Best Practices

1. **Start Conservative**: Begin with strict limits and gradually relax
2. **Monitor Logs**: Check logs regularly to understand EA behavior
3. **Test First**: Always test on demo account before live trading
4. **Set Limits**: Use daily loss limits to protect your account
5. **Review Daily**: Check daily statistics and adjust as needed

## Troubleshooting

### EA Not Trading
- Check `Expert_EnableTrading` is true
- Verify AutoTrading is enabled in terminal
- Check daily limits haven't been reached
- Verify time filter settings

### Too Many/Few Trades
- Adjust `Inp_Risk_MaxTradesPerDay`
- Check signal parameters
- Review time filter settings

### Logging Issues
- Adjust `Inp_Log_Level` (0=Errors, 1=Info, 2=Debug)
- Check Expert tab in MT5 for logs
- Enable `Inp_Log_EnableDetailedLog`
