Read this related thread ... look at the code section "Variables for Handling of Licensing Restrictions", and for you query, specifically at "boolRestrictDemoAccount" and "dtRestrictExpiration".

EA limit code

Here is a sample of my own code that I use, but it is up to you to implement properly. I'm not offering any support on it. It is up to you to do the necessary research and learning.

{
   // Check Licensing Restrictions

Just restrict time on OnTick() function
 
Nguyen Phuong Hoang:
Just restrict time on OnTick() function

How can I do it ? For example, do not use it after 1 hour. Can you give an example

I gave you a complete solution which includes time expiration, where you simply put a deadline and activate it, yet ignored it!

I need a short and simple solution. All I want is that the robot will not be used after 1 hour.
