MQL Defender

Once some program can be purchased and used, at the same time someone can crack and copy it without authority. Therefore anyone can discover the methods and strategy you are using in your code. De-compiling of EX4 file can turn off any licensing you use trying to protect your program.

Our solution for MQL Code protection defends your expert advisors and indicators against de-compilation by putting the main functional into DLL. And it licenses EX4 files so that they are not working if someone copied your code to a new computer.

  • Hiding MQL code (main algorithm) to c++ dll
  • Verifying “check summ” of the file; if the code was changed, user is blocked
  • Storing all parameters used in EA on remote server. As a result, if someone cracked the DLL (what is very difficult), hacker can`t run it without that hidden options
  • Licensing. You can limit the code running on single PC or/and MT4 account. Thus if somebody share it, license will not work.


  • Product is one or more EAs or Indicators which you can group by the same template or general logic.
  • You can add several files as Expert Advisors, Indicators, Scripts or other resources to Product for MQL code protection.
  • Feel free to edit all parameters used in the protected Product at the Product tab of the web control panel.
