Implementation Guidelines

Coding Standards

1. MQL5 Best Practices

// Class naming convention
class CMarketStructure {
private:
    // Private members with m_ prefix
    double m_lastPrice;
    bool m_isInitialized;

public:
    // Public methods with descriptive names
    bool InitializeAnalysis();
    double CalculateStructureStrength();
};

// Error handling pattern
bool COrderBlock::DetectOrderBlock(string symbol) {
    if(!IsValidSymbol(symbol)) {
        Logger.Error("Invalid symbol: " + symbol);
        return false;
    }

    // Implementation logic
    return true;
}
