I need a copy trader

example:

I have 2 clients.

Client 1 I give a serial key that lasts a week, he will be able to use the Client EA and copy the operations for just one week.

The 2nd customer I give a one month key.

the difference is this access key manager.

So that I can create an access key valid for a certain period.

and that the client EA only works with this key.
