Help on adding expiration date to script and account number registration

If you use this logic (positive confirmation) allowed_until must be in the future.
I tested it with a future date and it worked.
datetime allowed_until = D'2024.02.11 00:00';
With past dates it detects expiry. This bit works ok too
if(TimeCurrent() < allowed_until)
Additionally, I will love to restrict the script to running only on some accounts numbers so it will not run with on every account except that which has been added in the source file. In help in this direction will be highly appreciated. thanks
Easy enough - the simplest way is to create a delimited string of the allowed accounts numbers and use StringFind() to check if the current account is in the list - you could do the opposite if you want to create an exclusion list.
An Array of account numbers is a bit more elegant, but needs a little more coding - if your list of account numbers is not too large, a string is easiest. If it runs just once during OnInit() it is unlikely to affect performance later on.

The first thing to do is use braces {} - omitting them has no benefit in my opinion
The MQL editor automatically generates code like this:
if(condition) { for(int i=0;i<total;i++) { if(condition) { } } }
This section of code should be made to follow that pattern - try that and see if it fixes the issue. If not, debug it
if (broker == allowed_broker) for (int i=0; i<ArraySize(allowed_accounts); i++) if (account == allowed_accounts[i]) { password_status = 1; Print("EA account verified"); break; }

lease I need some help in adding an expiration date to my script. I used the code below but even after the expiration time the script still runs. Additionally, I will love to restrict the script to running only on some accounts numbers so it will not run with on every account except that which has been added in the source file. In help in this direction will be highly appreciated. thanks
