Hey, Nevis is a good one, they offer good fees and profit share (depends on your volume). I'll also use Sterling Pro, they might have Fusion too.
I have few other serious alternatives: MGB Trading and United Traders. I wonder how I could get more info about stability of the firms. Want to pick the one with low fees and low probability of default.
How long was Nevis in business, anyone knows? Same question for MGB. Reg United Traders, they are since 2009.
