How do I simulated broker tick data?

I want to be able to create a piece of software that would allow me to save all tick data, along with spreads, etc from a real MT4 broker and then would let me replay it locally (by connecting to a local fake MT4 broker) and make trades with that information on real time using metatrader.

Basically I'm looking to develop a local dealing center for testing purposes.

I was wondering if something similar already exists and if anybody knows where I can find documentation about the MT4 protocol.

Any thoughts and links to related information will be greatly appreciated.

I will be looking to opensource the software.

Thanks,

Seb

There is an EA somewhere here that does that.

I saw it several months ago.

But I have no need for simulated testing, so I ignored it.

Basically I need to be able to be my own imaginary broker.

Yep.

Sorry I can't think of the name of it. Maybe someone else will.


Lots of people here seem to like a simulator called forextester.

Cheers.

Isn't that the same as using the strategy tester with a simulator? (except for the spreads)
