Need help implement a licensing system for my MT5 Expert Advisors

Hi,

I'm looking for someone to help implement a licensing system for my MT5 Expert Advisors.

The goal is to securely distribute my EA to clients while controlling who is allowed to use it.

Here are the approaches I've considered:

1. License Key Activation
   • Each client receives a unique license key generated by me.
   • The EA requires the license key to be entered in the inputs before it can run.
   • The license key can include an expiry date and account restrictions.
2. Server-Based License Verification (Preferred)
   • The EA connects to my licensing server/API on startup.
   • The server stores a database of authorized MT5 account IDs.
   • If the account ID is authorized, the EA runs normally.
   • If I remove the account ID from the database, the EA immediately stops working (or refuses to trade after the next license check).
   • I'd also like the ability to set an expiry date for each license.

I'm not sure if these are the best approaches, so I'm open to suggestions. If you have experience building secure EA licensing systems, I'd appreciate your recommendation on the most secure and reliable solution.

Ideally, the licensing system should support:

• MT5
• License activation/deactivation
• MT5 account ID binding
• License expiry dates
• Online license verification
• Protection against unauthorized copying or sharing of the EA
• Easy management through a web dashboard or admin panel (if possible)

Please let me know what approach you would recommend, how you would implement it, and examples of similar licensing systems you've built.
