Add License & User Control Protection System to My MT4 Expert Advisor (MQL4)

📝 Job Description:

I already have a finished MT4 Expert Advisor (EA) in MQL4.
What I need is a strong protection and license control system added to it.

The goal is to make sure that:

• I can control who is using my EA.

• I can see the name and surname (or account name) of each person who runs the EA.

• I can decide who can or cannot use it.

• If someone is not on my approved list, the EA should automatically stop or block trading.

I want to act as the master or admin, able to see all active users and disable any user whenever I want.

I’m not looking for complex web-based solutions or external servers, but a simple and effective protection system that works inside the EA or through a local master file/database (for example, a license file or master key system).

Main requirements:

• The EA should check if the user is allowed (based on name/account/license).

• It should display my name as the owner/developer.

• If the user is not authorized, the EA should show an alert and stop.

• The solution should be secure enough to prevent easy sharing or reverse engineering.

• I must be able to easily add or remove allowed users (for example through a list or file).

• Bonus if the system can record or display usage info like who is running the EA and how many times.
