Check the Free Harmonic Pattern Indicator with 7 types of patterns (ABCD, bat, butterfly, gartley, shark, crab and deep crab) detected on higher timeframe charts (H1-D1). The ABCD (or AB=CD) pattern is composed of three movements and four points. The BAT pattern has one leg more than the ABCD pattern, and one extra point (X). The Gartley pattern has two key rules. The butterfly pattern is a reversal pattern composed of four legs, marked X-A, A-B, B-C and C-D. The Crab follows an X-A, A-B, B-C and C-D pattern. GOLD Deep Pattern this is a slightly different version of the Crab pattern. The the shark pattern has some similarities with the crab patterns.

Each pattern might be turned on/off on the panel on the chart and all visual elements might be changed in the indicator settings.

Harmonic Patterns were invented by H.M. Gartley in 1932. In Profits in the Forex Market, Gartley described a five-point pattern (dubbed the Gartley). In his book Fibonacci Ratios with Pattern Recognition, Larry Pesavento used Fibonacci ratios to reinforce this pattern and provide trading instructions for the "Gartley" pattern. Scott Carney's "harmonic" books, in my opinion, provide the most in-depth examination of this pattern theory. Scott Carney also devised patterns like "Crab," "Bat," "Shark," and "5-0," which added a new level of complication to their trading rules, validity, and risk/money management.
Price/time variations that follow Fibonacci ratio connections and market symmetry dominate harmonic patterns. Fibonacci ratio analysis is applicable to all markets and time periods. These ratios are used to identify pivotal turning points, retracements, and extensions, as well as swing high and swing low points. These swing point projections and retracements (Highs and Lows) provide target and stop price levels.

A Harmonic Pattern is a technical analysis tool used in financial markets to identify potential reversal points in price trends. It is based on geometric price patterns derived from Fibonacci retracement and extension levels. Traders use Harmonic Patterns to anticipate potential trend changes, pinpoint entry and exit points, and manage risk effectively.

Common Harmonic Patterns include the Butterfly, Gartley, Bat, and Crab, each with specific criteria for recognizing them on price charts. These patterns consist of precise Fibonacci ratios between various price points, such as retracements and extensions. Traders apply these patterns to determine potential reversal zones where the price may change direction.

The efficacy of Harmonic Patterns lies in the idea that financial markets exhibit natural harmonic relationships, reflecting the inherent balance and symmetry in price movements. Traders often combine Harmonic Patterns with other technical analysis tools and indicators to confirm signals and enhance the probability of successful trades.

Traders need to use Harmonic Patterns within a comprehensive trading strategy, considering market conditions and risk management. While Harmonic Patterns can be powerful tools, they are not foolproof, and careful analysis and experience are crucial for successful implementation.
