Creating MT4 or MT5 EA for Multi-Currency Trading and managing

I would like to create an EA for multi currency trading and managing trades between different MT4 terminals.

The EA has to gather data from 3 or 4 terminals and calculate its values. After that it has to decide, what trade operations have to be made on two terminals. These trades have to be managed by the EA after they have been opened.
I will provide full explanation when we discuss the requirements.

Please apply to this job only, if you have done multi-terminal and multi-currency trading EAs before!
