I think it is difficult to learn a lot of useful TA on this forum, starting from scratch, however when you already have a reasonable foundation, then Jako's and RB's charts and explanations make a lot of sense, and tends to increase one's knowledge further. There must be quality texts out there, and the ASX website has an educational section and TA step by step lessons, with chart patterns that you can print.
