"Technical analysis":- is an industry term that more often than not sounds much more complicated than the actual process is. Really, it ought to be referred to as "price analysis", as this would be a more accurate description. Through the use of charted data traders around the world analyze their market of choice. The objective: determine future price movement. The means: understanding price movement patterns of the past.
Technical analysis is often dispelled as a myth, even a fool's errand. There are those who believe that price movement is completely random and completely unpredictable. True, technical analysis is never an exact science (predicting the future never is). However, the true fool would be he or she that ignores the power of technical analysis, particularly in the Forex market.
Technical analysis fails when traders fail to consider the fundamentals. Why mention fundamental analysis when explaining technical analysis? Simple, the one just doesn't work without the other. Fundamental factors such as political events, a hike in interest rates, unemployment rates and so on will impact the Forex market more substantially than perhaps any other market. Fundamental factors are often the driving force of major price movements. A trader focused on technical analysis cannot ignore Nonfarm Payroll on the first Friday of the month and expect his or her technical indications to be as accurate as the day prior. Notice the price movement shown in the following image; shortly after Nonfarm Payroll price reactions were wild; during such times technical analysis cannot be counted on.
Purely technical traders understand that certain political factors throw all other price forecasts out the window.
