How automated trading works, all busines process schema/flowchart

[edgars.rworks]

Hi,

I am writing paper on Resource management systems and I choose to write about Automated currency trading using EA's.

But now I discovered that there is no actual schema on internet, that explains how does it actually works, what kind of servers used, how strong security over the network and so on.

So question is : Does somebody have ideas where to search that kind of schema or flowchart, with explanations ?

I don't need full explanation over here, I just need a tip, that I actually can use to find what I need.

Thanks,

Good luck in trading :)
