DislikedFirst, I would like to say that I have found an over-abundance of information here on FF. I hope this helps other people in their Arbitrage journey.
Now, I've included a zip file that has the necessary components for Arbitrage EURUSD between IBFX and Alpari (you can use any 2 brokers you like, you just need to remember which is which).
Instructions for installing are in the zip file. I've also included a zip file in the zip file that has the Visual Studio 2010 source code for the dll.
What I'm hoping here is that we can improve on this....Ignored
Do you also have the option to read the openorderprice from the other broker terminal inside the DLL fiel? If not is it possible to add it also.
