DORMAN TRADING is my preferred FCM: A full clearing Member of CME Group & staffed with some of the nicest people in Chicago.
I think they're a great fit for professional or active GLOBEX traders. Previously I've cleared through some of the larger, publicly traded firms & I find the service, integrity and price point at Dorman to be superior.
The DORMAN DIRECT platform is top-notch. Its stability, quick data feed, one click execution & reporting are easy to understand & work very smoothly. It's a white-labeled version of CTS's T4 platform which has a reputation for reliability. I actually prefer it to TT's X-trader, which Dorman also offers.
The brokers here have always treated me respectfully and have been a genuine help.
I've been a broker before so I can tell when someone is genuinely interested in helping you succeed, and in building a long-term relationship. Although slightly smaller than some of its competitors, this is a first rate clearing firm (full-clearing member of CME Group) for active futures traders.
HIGHLY RECOMMENDED for electronic GLOBEX traders!
