License Manager for EAs & Indicators

I need a fully automated license management system.

I am open for suggestions how this should work.

The license system should work with my current EAs, I am looking for a solution that will allow me to manage the approved users of an EA.

I want the license system to manage EA licenses and allow me to login website or software where i can add and delete licenses for an EA.

The EA will need the license as a parameter, only then with a valid license it will be possible to trade. The license system will check if the license is valid. it should work on mt4 and mt5 In the webpanel i want to control the max allowed lot size, and balance. It should be possible to have an expiry date time, when the license will be not valid no more. need following features : Server protection (Licenses Management): I can add / remove / edit clients and products I can stop (disable/enable) the MQL project from server I can set a trial period for every client and product.
