Error from Indicator

[WalterSkinner]

I'm working on a new indicator, it's open in the editor. I can see it in the NinjaScript Explorer. It was recently attached to a chart, but is no longer attached to a chart. When I open an indicator settings menu from a chart, the output prints: "Error on calling 'OnStateChange' method: Object reference not set to an instance of an object."

I was not able to remove it from the chart because it was not available to click on in the indicator settings menu, so I closed NT and started it again. The error persists and I don't know how to get rid of it. Also the indicator is no longer visible as being able to be added to a chart from the indicator settings menu.

What are you supposed to do when this happens?

Hello WalterSkinner,

The error means that an object being used was null. From the message we can see that's happening in the scripts OnStateChange override. If this happens when you open the indicator menu the problem is in either State.SetDefaults or State.Terminated.

To figure out whats happening you would need to look at the code in the OnStatChange in the two states. You can try commenting out the custom code you added to see when the error stops happening and you can see the indicator in the list again .

I look forward to being of further assistance.
