Whatever you do, don't pay for an education
Whether you take a formal course of study or go on your own, you are going to pay for it - one way or the other - just look at how many come to ET and spin their wheels for ever. As to formal study, I have purchased a number of books - Wyckoff, Livermore, O'Neil, Mamis, Larry Phillips among others. I have found books by and about gambling and gamblers, and trading books that emphasize probability at least as much as technique to be most helpful (or at least interesting) to me.
However, I primarily relied on Richard D. Wyckoff's original trading course, which is now available for free. I'd hate to think of how I might still be floundering around, or more likely completely washed out had Wyckoff's course not been free and I avoided it because I didn't want to "pay for an education."
