Moving Average of Custom Indicator

[MasterSepp]

Hello

is there any possibility to take the Simple Moving Average of a custom indicator? I tried it with Volume and all worked well, but when I try it with the custom indicator, there is an error saying, that the argument can't get converted from a method into IDataSeries. How can I change this?
Current code:

Value.Set(SMA(CustomIndicator, period)[0]);

I hope, you can help me with the problem.

Regards,

Sepp

EDIT: solved. Had to enter CustomIndicator(), since it's a method as it looks like...

You are correct. You have to use the method call.

David,

You should not try to back set with 1 like that. SMA indicator does not take into account that you are changing historical values on its input series.
