I do not know of any here in Chicago that would let a newbie trade futures remotely. I do know experienced futures traders with established track records at firms who have been allowed to trade remotely, but it's not common. The typical Chicago prop futures business model has capitalization provided entirely by the firm.
Have a prepared strategy that makes sense before you approach one of these firms. I have clients who already trade at some of them, and I have clients who occasionally choose to go there - usually in Chicago, NYC, London, Singapore, Sydney, or Gibraltar.
