Thanks for the response, Robert.Miklas, in your order, Yes, No, Yes, Yes, No. IMO, a Professional Trader earns his primary income from trading. That can be his funds or the funds of others.
When I think of a Professional Trader, I think of someone on their second cup coffee by 6am, with at least one, if not several licenses. They can be found parked in front of Bloomberg Terminal in a corner office at J.P. Morgan in Manhattan, raking in profits with old money.
