What this feature does
Add Expiry inserts a date check into the correct init or tick handler so the program exits or refuses to run after the expiry date. Works for expert advisors, indicators, and utilities.
Choose Source mode to get modified .mq4/.mq5 you recompile yourself, or Compiled mode to receive a ready .ex4/.ex5 with expiry baked in.

1 Upload your EA or indicator source file
