I have never worked for a prop firm before, but I am considering making the move to one. For you experienced prop traders out there: are there big differences between firms besides payout/commissions etc..? Do most make you go through their training to teach you a certain style of trading? Is it more of an 'everyman for themselves' environment with little collaboration and idea sharing? or is it more of a team-based approach? Ideally, I am looking for a firm in NYC that has mentors/training beyond the basic level, (e.g. I don't want or need to sit in a classroom learning abut chart formations) and feels more like a company rather than a place that I go to from 9-4:30 to use their computers. Does this exist?
