getting data from custom indicator

[daglas]

Dear friends.
How can I get data from custom indicators? I download a few indicators and install them on my NT7, but how to get data from their bars?

daglas, plotted values are exposed automatically so accessible from other scripts programmatically, for all other internal series / variables, please modify the code as needed -

Also I trying to get data from different futures, in my multiindicator.
For example from 6B 6-11 (British Pound) , 6S 6-11, 6E 6-11 and etc.
I try to use Add("6B", PeriodType.Minute, 1);
or Add("6B 6-11", PeriodType.Minute, 1);
But I see phrase 6B 6-11 does not exists on instrument manger, But I know that all futures exists there because I have add them here.

Please try adding those as 6B 06-11 to use the correct expiry.

Thanks a lot it was the reason of my troubles.
Also I want to get data from different time frames for different futures. So I use such code
Add("6J 06-11", PeriodType.Minute, 1);
Add("6J 06-11", PeriodType.Minute, 5);
Add("6J 06-11", PeriodType.Minute, 15);
Add("6J 06-11", PeriodType.Minute, 30);
Add("6J 06-11", PeriodType.Minute, 60);
And when user change time frame I use such code
if (BarsPeriod.BasePeriodType==PeriodType.Minute&&Bar sPeriod.Value==5)
z=Closes[2][0]-Opens[2][0];
And I have message in log of control center - You accessing an index with a value is invalid since ***.
What does it mean? This data is unaccessable?

Great - please ensure you have a CurrentBars check running for all involved bars objects -

It does not matter, please do include the check for all involved series like below -

if (CurrentBars[0] < 0 || CurrentBars[1] < 0 .....) return;
