From yourself or if you give it to someone else?
For someone else, simply give them only the executable ".ex5" or ".ex4".
For yourself, simple set the ".mq?" file to a "Read-Only" file in Windows (which will make MetaEditor give a warning dialog box when you try to save changes)...
... or remove "write" permissions from the file at the Windows system level all together.

Thanks Fernando
setting 'Read-Only' in Windows is simple way for my own use.

Dear Forum Member
I have few final versions of Indicators, Classes and EA.
How can I prevent editing them further by accident ? Something like "PROTECTING" them from further unintentional edits.
