In financial technical analysis, a candlestick pattern is a movement in prices shown graphically on a candlestick chart that some believe can help to identify repeating patterns of a particular market movement.[1] The recognition of the pattern is subjective and programs that are used for charting have to rely on predefined rules to match the pattern.[2] There are 42 recognized patterns that can be split into simple and complex patterns.[3][4] Author Thomas Bulkowski takes an in-depth look at 103 candlestick formations, from identification guidelines and statistical analysis of their behaviour to detailed trading tactics. He makes important discoveries and statistical summaries, as well as a glossary of relevant terms and a visual index to make candlestick identification easy.[5]
