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

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

• 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

• Review time filter settings

Logging Issues

• Adjust Inp_Log_Level (0=Errors, 1=Info, 2=Debug)
