I have a series of MT4 indicators that I send to my friends. I need a software that I can run the EX4 file or MQ4 file through so that it puts the important fuctions in a DLL, so that it cannot be decompiled easily. I must be able to provide them with a unique key that can be enabled/disabled from my web server. I currently have 2 indicators that I can enable/disable on their end. I am not looking for anything fancy, it just needs to be stable and working.
