I've advanced to the stage where I'm ready to move from my bucket shop (IG) to a futures broker. About 95% of my trades will likely be emini S&P, Dow, Nasdaq and Russell. I've got no experience in this area, although after seemingly endless research I'm leaning towards IB. Feedback tends to be fairly positive and the set up looks goodish. Before I open an account, does anyone have any particularly strong fondness for any other brokers?
