Additional Details
To be more specific, it is widely stated that most day traders end up losing significant portions of their capital before becoming profitable. The ones who are profitable from the get-go are supposed to be rare. What I have read is that it usually takes a year before one learns the ropes well enough to be consistently profitable. If one does get through this learning phase successfully, what percentage of one's capital should an "average" successful trader expect to lose during the first year? I've heard of people losing up to 75% before making a turn around and then making enough on a weekly basis that they can live off their earnings.
