Implementation Details

Detection Logic

bool IsMiniContract(string symbol)
{
    if(StringFind(symbol, "m") >= 0 && StringLen(symbol) > 0)
    {
        string baseSymbol = StringSubstr(symbol, 0, StringLen(symbol) - 1);

            return true;
    }
    return false;
}

Position Sizing

double GetMiniContractMultiplier(string symbol)
{
    if(!IsMiniContract(symbol))
        return 1.0;
    return 0.1; // 0.1x for mini contracts
}

Correlation Detection

string GetBaseSymbol(string symbol)
{
    if(IsMiniContract(symbol))
        return StringSubstr(symbol, 0, StringLen(symbol) - 1);
    return symbol;
}
