Knowledge of technical analysis is not so much, it is important that you need to select the materials to learn the best knowledge. Some online lectures and document files of some traders are often very vague and have a lot on google, but those are quality documents because I have read and tried them. I think you should spend a few tens of dollars to buy a book by Dr. Alexander Elder, called "The new trading for a living". I have learned a lot of experience from Elder's sharing.
