Ho to apply a Custom indicator over another Custom indicator

New comment

Hi everyone,

I'm brand new with MQL4, I'm tryng to apply a moving average to another moving average.

I'm able to call my two custom averages into MT4 e to plot them.

 But I want to apply the second average (yellow/blue) to the first one average (red); instead all I can do is to apply them to price (see the image attached below).

How can I  accomplish this?

 

Thanks

 

average

No you are not. You are trying to apply it to a custom indicator that has 3 buffers, not one. Can't be done. You'll have to make a new indicator
  1. Get Red. Detailed explanation of iCustom - MQL4 forum
  2. Calculate the MA on the red buffer. iMAOnArray - Technical Indicators - MQL4 Reference
  3. Populate blue or yellow based on the MA slope. See a colored MA in the codebase.
