I have a custom indicator that have values plotting on each bar.
I want to get the MAX and MIN values from the prior day. F.e. I'm using 15-minute timeframe, and I need to find the maximum and the minimum of that values.
How can I do that?
And one more - how do I need to code to "delay" the first day on the history? It will not be working good, because if I have no data before - there are no values of prior day available.
Thank you!
