access Series value from OnRender

[ttodua]

I have frequent problems in OnRender, when I call:

myPlotSeries[CurrentBars[0] - idx]


"You are accessing an index with a value that is invalid since it is out-of-range..."

However, GetValueAt(idx) always works.

is that expected behavior and are we always advised to use getvalueat in OnRender?

Hello TazoTodua, thanks for your post.

Yes, you should always use GetValueAt when using OnRender because it is asynchronous to the bar update logic. It's not always guaranteed that indexing a series will be accurate.

Kind regards.
