A chart pattern or price pattern is a pattern within a chart when prices are graphed. In stock and commodity markets trading, chart pattern studies play a large role during technical analysis. When data is plotted there is usually a pattern which naturally occurs and repeats over a period. Chart patterns are used as either reversal or continuation signals.
Traditional Chart Pattern
Included in this type are the most common patterns  which have been introduced to chartists for more than a hundred years. Below is a list of the most commonly used traditional chart patterns:
- Double Top Reversal
- Double Bottom Reversal
- Triple Top Reversal
- Triple Bottom Reversal
- Head and Shoulders
- Key Reversal Bar
- Flag and Pennant

Harmonic Pattern utilizes the recognition of specific structures that possess distinct and consecutive Fibonacci ratio alignments that quantify and validate harmonic patterns. These patterns calculate the Fibonacci aspects of these price structures to identify highly probable reversal points in the financial markets. This methodology assumes that harmonic patterns or cycles, like many patterns and cycles in life, continually repeat. The key is to identify these patterns and to enter or to exit a position based upon a high degree of probability that the same historic price action will occur.
Below is a list of commonly used harmonic patterns:
- Deep Crab
Traders use the Potential Reversal Zone (PRZ) as an important level of support/resistance in their trading and price action strategy.
In technical analysis, a candlestick pattern is a movement in prices shown graphically on a candlestick chart that some believe can predict a particular market movement. The recognition of the pattern is subjective and programs that are used for charting have to rely on predefined rules to match the pattern. There are 42 recognized patterns that can be split into simple and complex patterns.
Steve Nison is the one who introduced candlestick pattern from Japan to the West. There are hundreds of candlestick pattern available which are discussed in Steve's book Japanese Candlestick Charting Techniques.
