Learning how to trade is much more difficult than school. In fact, you will need to go to school to learn some of the statisitic, business, and economic concepts, which will be needed to ground your trust in your systems and your decisions.
Trading is not like a course that you can just read and learn. It is a combination of courses, and you won't even know which courses to take, because everyone has different answers...and majority of them are wrong. The one who knows will not tell you outright, but will give you hints, which you wouldn't be able to tell until after you have learned and research on the concepts and rationales.
If you like trading, then go to school and study business. Browse the archive of this site often. It contain a lot of good information if you can filter out the BS.
Side note: Dan Zanger was a really lucky guy. He really doesn't know how to trade. He just doesn't have all the knowledge needed to trade to make it a profession, and I doubt he has the proper combination of knowledge for professional trading.
