I've an strategy that it seems working fine in chart but when I try to backtest in Strategy Analyzer crashes and it doesn't show anything.

On output shows the next:

Strategy 'Strategy/-1': Error on calling 'OnOrderUpdate' method on bar 567: Object reference not set to an instance of an object.


It seems the problem is inside OnOrderUpdate method, what i should check or look? I can't see the exact line where the error is throwing.

Hello franjcy,
Object reference not set to an instance of an object means some object you used was null. One example would be Order variable that you are using inside OnOrderUpdate.

To find the specific line having an error you can add prints between each line of your OnOrderUpdate code and then look to see what the last print before the error was, the next line would be the line having the error.

I think I found the line that triggers error.

I'm using "ChartBars.Bars.Count" and it seems in Strategy Analyzer is null? If so, how can i do to get the total of bars at that moment ?

how can i do to get the total of bars at that moment ?

Isn't that just CurrentBar?

Uff, absolutely correct, sometimes I forget such simple things.

Thanks to all, all have been fixed.
