Just out of curiosity: This is the most eccentric programming petition I have read for quite some time. Why on earth would somebody want to use the indior that you just posted in source code form, composed by somebody else (I dont know how use the mq4 language) altered with such a bizarre limitation?

Sounds like you want to market it.

Also, the only way you can really expect this to not be decompiled by somebody else is not to distribute it.
