I thought 256 values are cached, but accessing other bars would fetch the data from the source. Is that correct or would I get an error when trying to access bars that are more than 256 bars in the past?

EDIT: I stand corrected. You will get an error. I just realized that I had never done it because I never need to see that far back to make a decision, in code or in life.Last edited by koganam; 01-14-2013, 11:30 AM.

Hello,
You should get an error if calling a bar greater than 255 unless
MaximumBarsLookBack = MaximumBarsLookBack.Infinite;
Will look something like this if not:
Error on calling 'OnBarUpdate' method for indicator 'YourIndicator' on bar 256: barsAgo needed to be between 0 and 255 but was 256LanceNinjaTrader Customer Service
