Object reference not set to an instance of an object

Yes, the debugger should be able to catch it - another idea would be using standard C# try / catch - http://www.ninjatrader.com/support/f...ead.php?t=9825

Thank you Bertrand.
I am infact running against replay data.
The thing is that sometimes this error appears in the strategy analyser and I still have no Idea where it is.
Would running in debug mode help? Will it give me the line that was causing the exception?

Sammy, I took a look and can't seem to reproduce those issues here - ensure you're running against realtime data, since on historical data it would return out of the OnBarUpdate(). Also you want to remove the FilterSeries, as it does not seem to be used in your cleanup version.

Hi

I see this error from time to time and I do not know what to look for to correct it. It compiles OK but on runtime i get this message in the log saying that there was an error calling"OnBarUpdate" method for indicator xxxxxxx on bar xxxxxx. Also, the indicator does not plot on my chart.

Attached is the indicator giving my the problem. I cleaned up the TSSupertrend a bit and added a few lines of code. I must have deleted more than I should have but there is no indication of what the problem is. If someone could point me in the right direction as to what to look for i would be grateful.

Regards

Sammy
