More separate sub_windows after inserting indicator

 
miro1360:

With #property indicator_separate_window can I add a new sub_window into main chart.

How can I add more than one sub_window?

You need an indicator to add a sub-window. 
 
But is it possible add 2 sub-window with inserting one custom indicator? Or I need insert it 2 times?

One indicator for one sub-window. 2 indicators for 2 sub-windows...
