For that reason I do not want to use .ex4 indicators anymore and get used or dependent on them and later on I cannot have same indicator again.
having decompiler for .ex4 makes difference but it is considered illegal so no-one offers to decompile .ex4, it is hard to find software and or service for that.
Black market or deep web might help in near future but that is uncertain as well.
I believe i explained myself. If you can help with decompiler let me know.
