I have several linux systems I would like to dedicate to trading. Right now, I am running my trading platform in a virtual machine inside the various linux systems. I was wondering if there were any brokers who specifically design platforms for Linux, where I can integrate software I have written with gcc and such. I'd also like to be logged in from multiple places on the same account. Is there any broker that facilitates this? I don't need colocation or special facilities, just reasonable fills removing liquidity in under a second or so, none of the high-frequency stuff. Any recs?
