Custom Indicator

I bought a custom indicator (CI) and would like to attach it to my own EA.  In the MT4, the CI signals appear in a separate window

However the CI is in ex4 format instead of an mq4 file.  I note in the MT4 data window that the indicators/signals have names and values.

Would I be able attach the customer indicator as it is not in mq4 and if so, how do I do it.  TQ 

Have found the answer.  EX4 can be added.
