How to use trades collection in an optimizer fitness

[guillembm]

Hello,

I would like to use this piece of code in an optimizer fitness:

foreach (Trade myTrade in strategy.SystemPerformance.AllTrades)
{

if (myTrade.MaePercent < 0.015 )

//Do Something;

}

I am getting the error: "An object reference is required for the non-static field, method, or property 'NinjaTrader.Cbi.SystemPerformance.AllTrades.get'"

What would be the right code?

Hello guillembm,

Thanks for your post.

You would need to exclude "strategy" in "strategy.SystemPerformance.AllTrades" in your loop. The code might read something like this.

protected override void OnBarUpdate()
{

    if (SystemPerformance.AllTrades.Count == 20)
    {
        foreach (Trade myTrade in SystemPerformance.AllTrades)
        {
            if (myTrade.MaePercent < 0.015 )
                //Do something
        }
    }
}
