Hi guys, I'm running a small fund with family and friend's money and we have about $1million. I want to look into designing systems to trade markets other than the ones which IB offer. My understanding is that the big IBs like GS, MS, JPM, CS, UBS, etc, all have electronic trading platforms designed mainly for funds/institutions. About such platforms I have a couple of questions. 1/ What would it take for me to open an account so I can trade my algos through these guys? Would they consider $1m - is it worth giving them a call? Or do I need double digits first. 2/ What programming language do these platforms normally use? Which software do they integrate with? Or is development and execution all in the one package? 3/ What sort of leverage do these guys offer? I'm guessing probably more than the 4:1 than IB does. And yes I'm aware that leverage cuts both ways, etc. Does anyone here trade or run a fund that executes their algos through these guys? Any thoughts/comments would be appreciated. Feel free to PM. Cheers.
