I opened with them a couple of months ago, I think they're pretty new. Anyways, they go through Farr Financial, which I've heard mixed reviews about, but so far so good. I've had accounts at IB, Mirus and MF and used Ninja and TT mostly. Their platform by comparison is more simplistic and not as configurable, but it's really fast and does the trick for my kind of trading (80-100/day e-mini and eurex). All in all, I liked Mirus the best before, but had some 'issues' with a broker regarding my rate and what it was supposed to be. Generic is a very simple company, but for what I need (no hassles from brokers and very fast fills) they have been great.
