Crap, FXCH delays each trade by around 10 seconds and even if you would make money with them, they don´t pay you out at all! Read the review all over the net, you can´t actually trade with them at all, and especially not arbitrage where you open/close trades in a few seconds. How do you want to do that if you get delayed 10 seconds already, the whole arbitage idea is not working with such a massive delay. And even if you would make money on FXCH, they don´t pay you out!
