Whats the proper way to catch this error in code? Plain try/catch block?

Error on calling 'OnBarUpdate' method

Hello FREEN,

You will need to resolve the error.

Find out what line is causing the error and see if you can get the entire error message which will tell you what needs to be corrected.


A try and catch is to keep an application from crashing when an error occurs. NinjaTrader already does this, logs the error, and disables the script without the entire application crashing.

Below is a link to an example of a type of error that can happen in OnBarUpdate().

Sorry if I´m unclear, I do not have an actual problem causing an error. My question is if it´s possible to catch this error (and others) inside code for display or other error handling (DrawText(), MessageBox or else..) in other manners than in the Output window.

FREEN,

Yes, you can use a plain Try-Catch block to debug your NinjaScript. Please see the 'Try-Catch' sample we keep in our help guide for more information: https://ninjatrader.com/support/help...tch_blocks.htm

If you need more advanced debugging tools than simple error messages in the Log and prints to your NinjaScript Output Window, you may want to look into debugging with Visual Studio. Please see the following help guide for more information: https://ninjatrader.com/support/help..._debugging.htm.
