DislikedATC is hands down the best ECN right now IMHO. No Freezes, Spread Widening (except naturally and briefly during news releases), No requotes and Better spreads and conditions than MBTrading - Better spreads than Dukascopy MT4 (even though Duka will be my backup once MT4 comes out of Beta). I trade Live with them and its great having a broker that I dont have to worry about since they NEVER trade against you.
