Actually, Technical analysis is much more of an emotional contest with you vs your mental ability. Many are able to learn technical analysis and its basics but most do not have the patience or the mental strength to survive in this market. Moreover day trading is even more difficult as everything happens so fast that before you can get a second thought about anything the time has already passed. So my advise to you whether it is stock is to prepare a strategy based on tools of technical analysis which you have learned. Then back test the strategy atleast on 30 occasions. Then you need to practice this strategy with your setup for atleast a 100 trades and you have to stick only to your setup and nothing else. Only this way you would be able to achieve success in day trading. Stick to your plan always even if it giving loss.
