Indicator not plotting on RTH only plots on 24/7

[dj22522]

Hello.

I've built a custom indicator but it doesn't plot on the price panel if Data Series is set to RTH (in this case CME RTH Futures).




It does plot if I select ETH or 24/7 or 25/7.


Help appreciated

Hello dj22522,

Thank you for your post.

Do any errors appear in the Log section of the Control Center regarding the indicator when you try to use it on an RTH chart? If so, what is the full text of the error?

Without seeing the indicator code I couldn't really say why that may be. Can you provide the code here or if you don't want to share it publicly, you can send an email to scriptingsupport [at] ninjatrader [dot] com with 3410656 ATTN Kate W. in the subject line and a link to this post in the body of the email with the script attached and I'm happy to take a look.

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

Hello dj22522,

Thank you for your reply.

The error indicates you are trying to access an index of a series that's not possible to access, this usually occurs because not enough bars are loaded at the time the script tries to access that series index. This is occurring somewhere within OnBarUpdate.

I would advise adding some prints to your script to narrow down exactly where the error is occurring.

This forum post goes into great detail on how to use prints to help figure out where issues may stem from — this should get you going in the correct direction. You can even add these using the Strategy Builder.

If you run into issues like we saw here, the above information will allow you to print out all values used to pinpoint where the error is occurring when using an RTH timeframe. It appears to be occurring on the very first bar on the chart, so I would also make sure you have CurrentBar checks if you're looking back several bars for a value. For example:

if(CurrentBar < 5)
return;

double myValue = High[5];

would correctly assign myValue the price of the high 5 bars ago without error; however, if you didn't check there were at least 5 bars on the chart first, you'd get an error like the one you see above.

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

Hello Kate:

Solved.

Thank you.

As you explained I was missing :

if(CurrentBar < 2)
return;

Please ignore the email I sent you.

Sincere thanks
