Disappearing indicator

[eleven]

Hello,

My custom indicator disappears from the chart when it calculates on:
- on each tick, or
- on price change

I don't see issue with the indicator disappearing when it calculates on:
- on bar close.

Please point me in the right direction on troubleshooting this issue.

Thanks,
Tom

Hello,

Thank you for the question.

Are you currently having any errors displayed in either the Log tab of the control center or the New -> NinjaScript output window while testing in these cases?

If so, can you provide the error for me to review?

I look forward to being of further assistance.

Yes. This is the error that I am getting:

2016-12-09 13:14:01:678|3|4|Indicator 'ZOsc8': Error on calling 'OnCalculateMinMax' method on bar 40981: The calculation results in unrenderable values.

Hello,

Thank you for posting this.

Is ZOsc8 the indicator you are creating or is this another indicator being called from the indicator you are working on?

The error message indicates that an invalid value may have been used for ZOsc8 and it was unable to calculate the Min/Max values for the chart.

If this error is coming directly from the indicator ZOsc8, you can likely find the problem by reducing the code until this error no longer happens. You can just comment out the code and continue to test the script to locate a more specific region of syntax that may be at fault.

I look forward to being of further assistance.

Yes. ZOsc8 is the indicator I'm creating. It is not a called indicator.

I will look at the Min/Max portion of the code to figure out what is going on. It is odd so me since I didn't have this issue when running the indicator on NT7.

Thanks,
Tom

Hello,

Thank you for confirming.

Yes if you are overriding the OnCalculateMinMax that would be the best place to start checking. You can likely confirm if that is the cause by just commenting the whole override out, and re test.

I look forward to being of further assistance.
