how to backtest multi symbols to combine them?

[duckick]

I see some strategies (hedging, arbitrage) that close all trades from many pairs in same time.
so how to backtest with many symbols in same time to strategies with many pairs combine?

tks so much

void OnTick()
{
    string symbol = _Symbol;
    
    if (symbol == "EURUSD")
    {
        // Execute your strategy for EURUSD
        // ...
    }
    else if (symbol == "GBPUSD")
    {
        // Execute your strategy for GBPUSD
        // ...
    }
    // Add more cases for other currency pairs
