Technical analysis Vs Fundamental Analysis

Which analysis is useful, technical analysis or fundamental analysis? None of them, one of them, or both of them? From my experience, I feel technical analysis is at least as important as fundamental analysis, yet our textbook only has a very simple and unapplicable introduction on technical analysis. Technical analysis is very useful in helping one entry in or exit out a position, one will be more successful if he/she can combine both technical and fundamental analysis in his/her investment practice. Among various tools for technical analysis, I feel candle stick charts is most useful, especially when it's combined with some technical indicators such as relative strength index, stochastic oscillator, etc. I will show you some of my experience in using technical analysis.
