Traded on their platform for about 2 weeks, platform would lock up during economic numbers, and their commissions were crazy, I wouldn't recommend them to anyone.
My partner and I have been speaking with them for a few months now. They seem to have good customer service. Our only issue to date (and has been for some time) is that the NDA that they asked us to sign (for API access) could give them legal rights over our strategies. Their lawyer never got back to us regarding a revised NDA. We have since chosen to go with IB's FX system. All we have to do is set up a paper trading account and we then have access to the API.
