I am a college sophmore in a Finance/Economics program and have been trading retail off and on for a couple of years. I've had mixed results due to inexperience but feel I have progressed and matured as a trader and have a good handle on what this line of work entails. I am positive that proprietary trading is the career for me and would like advice for what I can do to get started, or at least prepare and educate myself so that I become a desirable candidate when I do decide to enter the industry full-time. As of right now, I am almost 20, living in Tucson and attending UofA. I do not currently have the $25,000 most firms require as collateral but am willing to put up what I can to get licensed and get experience or training. While I would love to enter this career right now on a full-time basis (as I plan to within 2 years), I realize that this may not be possible and am just looking to get my foot in the door. Any input would be appreciated.
