Simple change on indicator for EA

Hello. I open this work with the intention of changing the indicator that is present in my EA code. This is an EMA 200 code, called STR-EMA. 

I will send a FINAL-EMA file for the exchange to take place. Furthermore, I would like a simple modification to FINAL-EMA, which is the possibility of changing the period in X candles (it is currently set to pattern 200)

Please note that the functionality of the EA should not be modified at any time.
