the "iCustom" or actually assigning the indicator's value to a variable inside the EA is how this is done...

examples:

double variable.a=iCustom(/*variable parameters*/);
double rsi=iRSI(Symbol(),1440,14,PRICE_CLOSE,0);

in MetaEditor, open the navigator window, click on the search tab, then type "iCustom()", then hit enter. In the toolbox window, the definition for the function "iCustom()" will be displayed.

hope this helps...
