Place Indicator on Sub-Window

How do you place an indicator on a sub-window? For instance, every time I try to drag a moving average to a sub-window, it automatically pops up to the main window.

The MA's used in MT4 are coded to draw on the main window. But you can open the code and change it.

Use the MetaEditor to change the code. On the 3rd line down change the following from:
#property indicator_chart_window

to

#property indicator_seperate_window

Then press f5 to compile the code and use as you wished.

Drag it and apply to "Previous Indicator's Data" or either "First Indicator's Data" depending on where you need to place it.

Thanks to both of you
