Technical Analysis (TA) refers to the study of past prices to develop a view about future prices. TA is a broad and all encompassing term. All the methods listed here form part of the TA family - Fibonacci, Chart Patterns, Elliott Wave, W.D Gann and Astrology etc, just to mention a few. There is much to study within TA. If you are one of those people who enjoy a journey as much as they enjoy arriving at their destination, then as long as you resist trading before you can independently validate an idea, you'll love your trip through the amazing and colourful world of TA.
