MT4 EA question

 
Mu dude is a manual trader. Is there a feature in MT4 which restricts him from trading outside of certain hours?  Or can EA be developed to stop trading outside of these hours? Ideally I would like the EA to stop him from opening a position, failing that it would close the position immediately if it's opening as i said outside of those hours. He wont have access to the server which the platform is running from but can open and close positions as long as it's within those hours. He has issue with discipline and he says this is his way of developing that going forward. Thanks in advance.  
 

What does "Mu dude" mean?

If it is his account let him learn by his mistakes.

If it is your account, change the login password and don't let him near it!

 
meant my dude. It's not that simple, but thanks. 
 

Build an EA that executes trades by receiving signals .

Split your friends account into two 1/3 + 2/3 .

Keep the password for the second account .

Let him trade on the first account and copy the trades to the second account automatically only within specific hours.
