Copy Trade System

I have an EA which using for my private clients on my VPS.

Now they using of EA with MT4 like normally use. But I want to have a copy trade basis of my EA to all of our clients.

For example if I have 50 clients I don't want to run 50 MT4 for each one. I want that all of them getting the copy of my own account via API,  or any thing you think is better. 

But remember I don't want to run MT4 for each our clients. I mean is send the request for MT4 Server to Buy or Sell position .

For security reason Source code needed.
