unexpected outOfRangeExeption when calling indicator

[GKonheiser]

Why would I be getting an out of Range Execption when calling a 20 period LinReg on Closes[1] 1 bar back when Closes[1] contains 141 bars?

double test2 = LinReg(Closes[1], 20)[1];

Hello GKonheiser,

Thank you for your post.

Do you have the added series in the Initialize() method?
Are you verifying that there are enough bars loaded with a CurrentBar check? For example: if (CurrentBars[0] <= 20 || CurrentBars[1] <= 20) return;

Can you list the full exception that is caught or provide a screenshot of the message?

I dont have the seires added , I am just calling it in OnBarUpdate but there are over 100 bars in the Closes[1] series.

Hello GKonheiser,

Thank you for your response.

Closes[1] would only have data if added through the code. You still need to verify there are enough bars in the code.
