I have narrowed down my selection to a few choices. Please let me know your experiences with those choices and who you recommend. I don't have a series 7 or 56. 1. CY Trading Group 2. Broadstreet Trading 3. CTG Trading (they make you get a 56 though) 4. Lakestreet Trading I have researched a bunch of firms, but so far those ones have been responsive and answering all questions that I have for them. JC trading might be possible, but I do not know if I meet their share requirement.
