XS Markets has been the best trader I've had the pleasure of dealing with in the past three months. They've got wickedly low spreads, a trading platform that runs like a dream, and negative balance protection to keep me from worrying about the worst-case scenario. And when I've needed help, their customer service team has always been there for me, going above and beyond to make sure I'm happy. If you're looking for a trader to trust, I'd definitely recommend XS Markets.
