Indicator showing only on 1 char?

[Skechers]

Hello,

I had my own indicator on say Chart A, configured it, hit Apply & OK. I can see the indicator on the chart

I opened a new chart say Chart B, configured it, hit Apply & OK. I can see the indicator on the chart.

I then click on Chart A, and the indicator is no longer plotted.

When I applied the indicator on Chart B, a message was output: Indicator 'MyExpMA': Error on calling 'OnBarUpdate' method on bar 22082: You are accessing an index with a value that is invalid since it is out-of-range.

Obviously there is an error in bar indexing. But the error doesn't come up when I only use the indicator on 1 chart.

What could be the problem?

Thanks, Caesar.

Hello Skechers,

Thank you for your note.

That would be difficult to say without testing the indicator and reviewing the logic to see what may be occurring. Can you provide the custom indicator you are using? You can export it through Tools > Export > NinjaScript Addon. Do not check the box to export as a compiled assembly or I will not be able to review the logic. Please attach the resulting .Zip file to your reply.

Thanks in advance; I look forward to assisting you further.

Hello Skechers,

Thank you for your reply.

I suspect it's the use of static for your Series<T> variables. Try removing that so it's just this:

private Series<int> CrossDirection; // Define a Series<T> variable.
private Series<double> MyMAExp; // Define a Series<T> variable.

I'm not seeing it disappear off the first chart when this change is made.

Please let us know if we may be of further assistance to you.
