|
|
| \section overview Overview
|
| The RiskManager module provides comprehensive risk management for trading operations.
|
| It validates all trades against configured risk parameters before execution.
|
|
|
| \section features Features
|
| - Position sizing based on account balance
|
| - Volatility-based adjustments
|
| - Daily loss limits
|
| - Trade frequency limits
|
| - Margin and leverage validation
|
| - Market condition analysis
|
|
|
| \section usage Usage
|
| \code{.cpp}
|
| // Example usage

| if(riskManager.Initialize())
|
| {
|
| // Validate trade
|
| if(riskManager.ValidateTrade("EURUSD", ORDER_TYPE_BUY, 0.1, 1.1000, 1.0950, 1.1100))
|
| {
|
| // Proceed with trade
|
| }
|
| }
|
| \endcode
|
|
|
| \section configuration Configuration

|
| double sl = price - 5.0 * _Point; // 50 points SL
|
| double volume = riskManager.CalculatePositionSize("XAUUSD", price, 50);
|
|
|
| if(volume > 0 && riskManager.ValidateTrade("XAUUSD", ORDER_TYPE_BUY, volume, price, sl, 0))

| \section common_issues Common Issues
|
|
|
| \subsection validation_failures Validation Failures
|
| - **Symptom**: Trades are being rejected by risk manager
|
| - **Solution**:
|
| 1. Check error code using GetLastError()
|
| 2. Verify risk parameters
|
| 3. Check account balance and margin
|
| 4. Review market conditions
|
|
|
| \subsection slow_performance Slow Performance
|
| - **Symptom**: Risk validation is slow
|
| - **Solution**:
|
| 1. Reduce ATR period
|
| 2. Disable unused validations
|
| 3. Check system resources
|
|
|
| \section error_codes Error Codes
|
|
|
| | Code | Description | Action |
|
| |------|-------------|--------|
|
| | 1 | Invalid parameters | Check input values |
|
| | 2 | Exceeds daily loss limit | Reduce position size or wait for next day |
|
| | 3 | Too many open trades | Close some positions or increase limit |
|
| | 4 | Too many orders today | Wait for next trading day |
|
| | 5 | Insufficient margin | Deposit more funds or reduce position size |
|
| | 6 | High volatility | Wait for calmer market conditions |
|
| | 7 | Spread too wide | Wait for better market conditions |
|
| | 8 | Market closed | Check trading hours |
|
|
|
| \section best_practices Best Practices
|
| 1. Start with conservative risk settings
|
| 2. Regularly review risk parameters
|
