Wisdom Trading is my broker of choice for futures trading systems. They run Trading Blox, which I use on this site for all simulations and testing, and they offer trading systems to clients and/or execution of your own system on your behalf (so that you do not have to run the daily grind management of it). They have one of the most extensive market coverage (important for diversification), really know their stuff, and are very friendly and professional to boot.
They have my full recommendation!
