Reading values from multiple indicators in a subwindow


Good Day all,

So I've plotted an RSI indicator to the main chart and on the same window (of the RSI), I've plotted several MA's.
Anyone know if there's a way of getting the MA values relative to the subwindow?

I was able to get the MA handles from the subwindow but when retrieving the values, I get the same values as if they were plotted onto the Main Chart.
Please see below.

RSI with MAs

Eg. I have a level 90 on that subwindow and would like know when the MA's touch the 90 level.
