Error: Object reference not set to an instance of an object

[suprsnipes]

Hi,

I have an indicator that is having problems periodically. The error message I am receiving in the log is as follows;

Error on plotting values to chart data box for indicator 'Combo'. Please check the 'OnBarUpdate' method: Object reference not set to an instance of an object.

I'm not entirely sure what could be causing the problem but I have tried various methods as suggested online with regards to checking current bars as well as try/catch but when the error occurs the plots dissapear from the chart until I reload the indicator where it may or may not dissapear again.

Appreciate the help.

suprsnipes, is this behavior reproducible for you consistently or would it just occur every now and then? Do you use the .Reset() method in your custom script? Would you mind if we attempted reproducing with your script and workspace on our end here?

Thanks,
