"TA doesn't work" is one of the absolute dumbest things I've heard someone say. It's been working for over 100 years. What people get hung up on is that someone's analysis can't be guaranteed 100% when they do it correctly, and that most people don't really understand how to do proper technical analysis in the first place. They ignore rules, guidelines, etc. and then someone else who doesn't understand TA sees them get it wrong and comes to the conclusion that it doesn't work. Learn how to be better critical thinkers.
