Getting bar's index function?

[[Deleted]]

Hi,

I am searching for a function of getting a pointed bar's index. Below is the code of calculating last 4 candles height in pips. I would like to know how to program the same thing only from a certain point, for example (as attached in the image) from the red line in the screen. Thanks for any advice.

Best regards,

sacrif
