P&L of previous trade

[BigDog008]

Trying to test a money management system out....

say I have 10 trades...when I try and print the last trade using

Print (Performance.RealtimeTrades[0].ToString());

it prints the very first trade I made, not the last trade made...

any ideas?

BigDog008, please check example 1 from this link for the indexing used - http://www.ninjatrader-support.com/H...tionClass.html

Thanks Bertrand....

I'm assuming then what's posted here was a typo? .... if not a typo, confusing... it says Get the last completed real-time trade, then it says at index 0...

protected override void OnBarUpdate() 
{ 
    // Check to make sure there is at least one trade in the collection 
    if (Performance.RealtimeTrades.Count > 0) 
    { 
        // Get the last completed real-time trade (at index 0) 
        Trade lastTrade = Performance.RealtimeTrades[0]; 
 
        // Calculate the PnL for the last completed real-time trade 
        double lastProfit = lastTrade.ProfitCurrency * lastTrade.Quantity; 
 
        // Pring the PnL to the Output window 
        Print("The last trade's profit is " + lastProfit); 
    } 
}

Hi there, which entry contains the typo? I checked the link Bertrand sent you and didn't see it. Anyways, the performance arrays are actually reverse indexed (most recent is largest value, first is at index 0).

The general idea to get the most recent trade's profit:

if (Performance.RealtimeTrades.Count > 0)
{
    Trade mostRecentTrade = Performance.RealtimeTrades[Performance.RealtimeTrades.Count - 1];
    if (mostRecentTrade != null)
    {
        double profit = mostRecentTrade.ProfitCurrency;
    }
}

That code hasn't been tested, but it should show the general idea. I actually created a reference sample that I pulled this code from. There are many more comments in the code sample located here.

Let us know if you have any other questions.
