Input appreciated on these three firms as far as trading remote. Strengths/weaknesses of each firm, reliability of quotes/feeds/platforms, bullet formation (hotkey or separate platform), fees, overall experience. I have Series 7 and 10K to contribute. My volume would initially be low (100-200 share blocks) as I will be trying out strategies I have been successfully papertrading. This is a tough decision to make and would like to hear from those of you currently trading with those firms.
