indicator on indicator

[mich]

Hi, how is it possible to make an indicator of a (custom) indicator (example: the exp. MA of another exp. MA)? Ive tried iCustom, but not accepted as "Symbol". Also Ive Tryed iMAOnarray, but somehow the iMAOnarray of the fist indicator's array is not giving more than a constant value for all the second indicator.¿ Is it possible to transform icustom in some kind of stringvalue that can be used with indicators? or ¿how should be an indicator array transformed to be used with iMAonarray? (if also tryed ArraySetAsSeries, with no succes by now) Well, if oneone can help me it would be great, cause it is already some days even dreaming about this problem !!! :-)

Here is one way:

IT WORKS! IT WORKS!!!!! Waw, thank you so much, I will study the code, to fully understand the way iMAOnArray works, cause I had not been able to make it work properly in my previous attempts.

Thank you for your answer and for this efficient elegant pice of code !!!
