opening locked script

 
How do you open an EA script that is locked in the editor?
 

Locked?

 
I bought an EA from Ebay that is not editable in the editor cause i couldnt access the script. I want to be able to go in there and change the timeframe from 30 mins to one hour
 

What did you buy?

If you have two files, one ending in MQ4, that one opens in the editor. That file is the "source code".

If you only have one file, ending in EX4, you cannot modify it. That file is the "binary executable".
