I need a license System for MT4 / MT5 EAs

Hi,

I want to control from remote if an EA has a valid license and is allowed to trade or not.

The license System should manage EA licenses from remote. I want to log into a (web based) 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.

In the webpanel i want to control the max allowed lot size, and balance.

It should be possible to have an expiry datetime, when the license will be not valid no more.

Thanks!
