DataSeries.Reset()

I think that's what I'm doing but it doesn't work. Should [0] be replaced by [1]?
I also have
if (CurrentBar < 1) return;
before my code

For the 'on bar close' part of code, you would need to reference one bar back further compared to your original code, so [0] would become [1] and so forth.

For the part where you like to see updates on each incoming tick, just access the last value [0].

Do you notice errors in the log tab as you apply this code?
