Technical analysis is the use of past price action and volume information to predict future price movements. Though there are exceptions to this, as a general rule, longer term investors tend to base their trading decisions on fundamentals and shorter term traders tend to focus more on technical. Technical analysts use charts and other tools to identify patterns that can suggest future activity.
From observation, active traders tend to focus more on technical than fundamentals, they still have an understanding of fundamentals and some consider fundamental factors in their trading decisions along with their technically based analysis। There is much debate as to which method is better as there are successful investors and traders who focus only on fundamentals (a great example being warren buffet) just as there are those who are successful and focus only on technical (a great example being Richard Dennis).
