Error on calling 'OnBarUpdate' method on bar xxx --> Which method?

[Gerik]

Hello,

during development, I often get "Error on calling 'OnBarUpdate' method on bar xxx" due to mistakes/bugs while writing code.

I have nested methods. How can I identify in which method this error is occuring without using print statements. Can I use any debugger? How can I use Visual Studio to identify the method where this error occurs? Do I need Visual Studio at all for that?

Sincerely
Gerik

Hello Gerik,

It is possible to use Visual Studio debugging. While we can direct on how to set this up, our staff is not able to assist with using Visual Studio.

Our team is going to advise using prints and reducing to understand behavior and do debugging.

Hello Chelsea,

thank you for your quick answer and the hyperlinks.

I do not want to set break points. I want NinjaTrader to show me in which method the error occured. I mean the latest method that has been called. Can I identify the method somehow instead of using break points? With break points I just poke in the dark.

Kind regards
Gerik

Hello Gerik,

I would not be able to assist with using Visual Studio.

However, you can add a print above each line to see which print is the last to appear to identify the line causing the error.
