iRSI Trend Line

[[Deleted]]

Hello,

I am writing a EA where I am using the iRSI.
When I run it in the Strategy Tester window, it only appears after the test is finished, not in real time like the price.

Is there a way to see it in real time?

Also, and more important. I am trying to draw trend lines in this iRSI, but I dont know how to find the name of the window, because it is not a custom indicator.

Anyone would know how to draw this trend lines?

Thanks,
Erick
