EA from .ex5 ?

 
I'm not a programmer so I ask the following question. Is it possible to create an EA using an indicator that only has the .ex5 but not the .mq5?
 

Yes its possible if the indicator provides buffers, You can see if indicator is providing buffers using Data window

If buffer exists it can be read by iCustom

If indicator creates objects then its also possible by reading Objects

If indicator provides Alert or Prints anything then its also possible to create EA by reading the Log file for any new prints.

If indicator does not provide buffers, alert, prints or objects then its not possible to read indicator calculations and make EA.
