Remote Trade Copier (Master and Slave) Using MySQL Database

Connections would be made between master sending signals and slave receiving signals using a mysql database. The receiver EA connects to database to authenticate for valid user and expiry date (Unix timestamp) granting permission to pull signals.

Must allow for unlimited connections. Connections must be fast.

The actual Ea can be a two in one (Master and Slave) or a single Ea file that separates the function of each. Permission to make changed from stated direction if it will make work easier.

Preferably, I would not want to use any dll. Also, bidder should have done a similar project before. Source code and any other dependent source file(s) must be supplied. 

A sample project is a blend of the underlisted links
