Trading Indicator Overlay MT4

Hi there, on my iPhone i have two indicators overlaying each other in the same window in the MT4 trading platform. I can’t seem to do the same on my desktop MT4 trading platform. Does anybody know if this is possible?

Yes, it’s possible.

Could you perhaps give me an idea how to do this please?

Add another indicator to an indicator window.

Can you be more specific on how to do this? Newbie me

Add indicator at main window
Not indicator window
