What are Harmonic Patterns and How Do They Work?

Harmonic patterns are a technical trading tool used to identify potential price reversals in financial markets. They are based on the idea that price movements are not random, but instead, follow certain repeating patterns.

Harmonic patterns are based on two key elements – Fibonacci ratios and geometric shapes. The Fibonacci ratios are used to identify potential price reversals by looking for specific patterns and ratios. The geometric shapes are used to create a visual representation of the patterns, which can help traders identify potential reversal points more easily.

The most common harmonic patterns include the Gartley, Butterfly, Bat, and Crab patterns. Each of these patterns is made up of four distinct legs and is constructed by connecting different Fibonacci ratios. The ratios used to create these patterns are the 0.618, 1.27, 0.786 and 1.618 retracements. The pattern is created by connecting points at these specific Fibonacci levels.

Once the price reaches one of these levels, the pattern is complete and a potential price reversal can be identified. Traders use this reversal point to enter trades in the opposite direction of the current trend. For example, if the pattern is completed at a 0.618 retracement level, this could indicate that the price is about to reverse and head in the opposite direction.

These trading patterns can be used in combination with other technical indicators to help traders make more informed trading decisions. They are best used in conjunction with other technical analysis tools such as trend lines, support and resistance levels and chart patterns. It is important to remember that these patterns are not a guarantee of success and should be used as part of an overall trading strategy.

4 Types of Harmonic Patterns

There are four main types of harmonic patterns: the Gartley pattern, the Butterfly pattern, the Crab pattern and the Bat pattern. Each of these patterns has a specific set of rules that must be followed to identify it correctly.

Gartely Pattern

The Gartley pattern, also known as the Gartley 222, is one of the most recognizable and reliable chart patterns used by technical traders.

The Gartley pattern is based on the Fibonacci retracement levels of the AB=CD pattern. The AB=CD pattern is a four-leg reversal pattern that consists of two legs, an A-B leg and a C-D leg, which are joined by a common point.

The Gartley pattern is a reversal pattern, which means it signals a potential change in trend. When the pattern is formed, it is used to identify potential buy and sell opportunities. The key elements of the Gartley pattern include the XA leg, the AB leg, the BC leg, the CD leg and point D.

The XA leg is the first leg of the Gartley pattern and can be an uptrend or a downtrend. The AB leg is the second leg of the pattern and should be a retracement of the XA leg. The BC leg should be a retracement of the AB leg, and the CD leg should be a retracement of the BC leg. Point D is the final point of the pattern and should be a retracement of the XA leg.

Butterfly Pattern

The Butterfly harmonic pattern is formed when a price action meets certain criteria and can be used to anticipate possible price movements.

The Butterfly pattern is formed when four price points (A, B, C and D) are connected by three straight lines. The pattern is considered to be complete when the price action meets certain specific criteria. The A point should be a bullish retracement of the prior price move, and the B point should be a bearish retracement of the prior price move. The C point should be a bearish retracement of the AB move, and the D point should be a bullish retracement of the BC move. Furthermore, the AB and CD moves should be equal in terms of price and time.

The pattern is believed to be a reliable indicator of a potential price reversal. Traders who use the pattern may look for opportunities to buy or sell when the pattern is complete. The pattern is also used to measure the strength of a trend and can help traders determine when to enter or exit a trade.

Crab Pattern

The Crab harmonic pattern is a chart pattern used by traders to call potential market reversals. It is named after its shape, which resembles a crab’s claw.

The Crab pattern usually appears in a downtrend and consists of two legs. The first leg is a bearish impulse wave, and the second is a corrective wave. The corrective wave often takes the form of a crab, in which price action moves in a zigzag pattern, forming three distinct peaks and two distinct troughs. The pattern is considered complete once the corrective wave has formed the three peaks and two troughs.

Traders typically wait for the pattern to be completed before entering a trade. Once the pattern is completed, traders enter a long position when the price breaks above the corrective wave. The idea is that the price action will continue to move in the direction of the original downtrend.

The key to trading the Crab pattern is to identify potential targets using Fibonacci levels. The most common target is the 161.8% Fibonacci extension level, which is the highest point of the corrective wave. Other potential targets include the 127.2% and the 88.6% Fibonacci extension levels.

When trading the Crab pattern, traders must also be aware of potential stop losses. Traders should place their stop loss below the most recent swing low or below the corrective wave’s second trough. This action will ensure that downside risk is limited.

Bat Pattern

The Bat pattern can be used by day traders and swing traders. The pattern is composed of two legs and two converging trend lines. The first leg is an impulse move in the direction of the trend, and the second leg is a corrective move in the opposite direction. The second leg is the Gartley pattern, which is also composed of two legs and a converging trend line.

The pattern is considered to be reliable when the Fibonacci ratios are respected. The Fibonacci ratios used in the pattern are the 0.382, 0.50 and 0.618 retracements. Traders will look for these levels to determine the potential reversal points of the pattern. When these levels are respected, the pattern can be used to identify potential reversals in the markets.

How to Trade Harmonic Patterns

When using these trading patterns, it is important to pay attention to the rules of each pattern. For example, the Gartley pattern requires that the price move in a specific way before and after the pattern is identified for it to be considered a valid pattern. Once the pattern has been identified, traders can then use the patterns to identify potential trade opportunities.

Traders should also pay close attention to the Fibonacci levels associated with the pattern, as they are often used to identify potential entry and exit points for trades. Additionally, traders should pay close attention to the price action leading up to and following the pattern, as it can provide valuable insight into the probable future direction of the market. Finally, traders should watch out for any news or economic events that could potentially affect the market, as these can also influence the outcome of the trade.

Risks of Trading Using Harmonic Patterns

Risk is an inherent part of trading, and this is especially true when it comes to trading using harmonic patterns. Because these patterns are based on Fibonacci ratios, they can be highly accurate when used correctly. However, they also involve a certain amount of risk, and traders need to be aware of these risks before attempting to trade with harmonic patterns.

  • False signals: The most obvious risk harmonic traders face is that they are subject to false signals. This situation occurs when a pattern is formed, but the price fails to move in the expected direction. Harmonic patterns are based on historical data, so there is no guarantee that a pattern will repeat in the future. Therefore, it is important for traders to use a combination of other technical indicators to confirm the validity of a harmonic pattern before entering a trade.
  • Accurate interpretation: Another risk is that the patterns can require an experienced trader to accurately interpret them. Since harmonic patterns are based on complex mathematical relationships, it can be difficult for new traders to accurately interpret them. This is why it is important for traders to practice with demo accounts before entering into live trading.
  • Subjectivity: A third risk related to harmonic patterns is that they can be too subjective. Traders can interpret the same pattern differently, leading to alternative trading decisions being taken. It's important for traders to be consistent in their approach when trading with harmonic patterns.
  • Overtrading: Forex traders should also be aware of the risk of overtrading when using harmonic patterns. Traders can become too eager to enter into trades when they spot a harmonic pattern, which can lead to a large number of trades being taken in a short period of time. A trader could lose money if the trades do not go as expected.
