In your course of learning, also remember a fundamental fact about technical analysis. No indicator can precede the event it diagnoses. In other words, all indicators react to price and can not tell you what price will be in the next time frame.
Another fundamental aspect of TA is that the signals you get from a particular indicator should be viewed with a probabilistic mindset. You will never get 100% precision from your indictor, but the signals are there to try and give you a better than random entry. TA signals are meant to keep you doing the right thing, i.e buy low, sell high.
You should always use TA as part of a trading system (risk control, money management etc.) Also, back test your system. you are looking for a system with positive expectancy.
