i use oanda, and they seem to be much better than any mt4 broker.
i need an mt4 broker for my EAs. North Finance is currently at the top of my list, but that changes every day. the problem is that all will change soon with the new legislation: search for posts by kasparfx or forexfun on this. they both have info everyone needs to read.

realize the universe is one thing,
and attach it to your body
