Good Day...

I just would like to ask if anyone have tried to compare a certain price (eg. EURUSD) from 2 different sources using scripts or EA?

Thank you very much.

Just for curiosity. I am trying to develop a .net application which is by the use of DDE server on the mt4 it will receive quotes from the platform then compare the prices. I have tested it and im not quite sure with the result. Do you have any idea on how maximize the use of DDE server?

WRONG. Same computer/IP address etc. He's my brother.

 
This would be good to check if a certain broker's prices are same to another but have a small delay then set a system that trades the laging broker and use the quicker one to close. Ive tried this visually and it is a fact only that in the case, the delay in the lagging broker was like 2 seconds so by the time a trade executes the price would have updated.
