Harmonic Patterns Cheat Sheet (PDF )

Harmonic patterns are widespread technical analysis tools in the forex market. Currency traders employ these geometric chart structures to predict future price movements in multiple financial markets. To explain, such formations establish from precise and fixed Fibonacci retracement and extension sequences to determine trend reversals trading opportunities. Hence, the harmonic repetitive progression of Fibonacci ratios explains the pattern nomination. Also, H.M. Gartley was the original founder of the first harmonic designs in history. Then Scott Carney got deeper in this field in his “Harmonic Trading” book. This PDF Cheat Sheet will deliver an overview of how to trade harmonic patterns with a full explanation of their trading rules, origin, and types.

Harmonic Patterns FAQ

What are harmonic patterns?

Harmonic patterns are a prominent technical analysis method in trading and investing that forecasts future financial market price changes. They employ Fibonacci ratios to form geometric patterns and predict probable market reversal moments. Harmonic patterns include the Gartley, Butterfly, Crab, Bat, Shark, and Cypher formations. Traders utilize a mix of Fibonacci ratios and price action analyses to spot and trade these patterns.
Harmonic pattern trading strategies often include rigorous risk management and position sizing. As well as a clearly defined trading plan with an entry and exit plan. While harmonic patterns can provide useful insights into market movements, they do have limitations and should be used in conjunction with further technical analysis tools.

Why does it matter in Trading and Investing?

Harmonic patterns are important in trading and investing because they can assist traders and investors in identifying probable market turning points. To clarify, traders can predict probable price fluctuations and alter their trading methods by spotting harmonic patterns. This is especially effective in turbulent markets where prices can shift direction fast. Harmonic patterns can assist traders in avoiding being caught on the wrong side of the market and can give opportunities to join or exit a transaction at a better price. That is why, you should invest your time in reading this practical harmonic pattern Cheat Sheet.

Who created the harmonic pattern concept?

The 5-point “Gartley” harmonic pattern concept was first created by Harold M. Gartley in 1932 in his “Profits in the Stock Market” book.
Then, Larry Pesavento improved the pattern by incorporating Fibonacci ratios and established trading rules in his book “Fibonacci Ratios with Pattern Recognition.” Pesavento and Bryce Gilmore also invented the butterfly pattern with Fibonacci ratios.
After that, Scott Carney is known for his work on the Gartley, Butterfly, Crab, and Bat patterns, and his two-volume text “Harmonic Trading of the Financial Markets” is considered the best work on these patterns. Carney added specific requirements using Fibonacci ratios to validate the Gartley pattern’s structure and identified specific reversal levels using the term “Potential Reversal Zone” or PRZ. Carney even designed additional 5-point patterns like Crab and Bat designs.

How many types of harmonic patterns are there?

There are several five-point harmonic patterns that investors consider in trading.
All of them have comparable setups. To illustrate, they merely differ regarding leg-length ratios and critical node positions (X, A, B, C, D). So, once you grasp one structure, the others will be pretty straightforward to understand.
The major cheat sheet of harmonics types includes a list of 6 patterns:

  1. Gartley structure
  2. Butterfly pattern
  3. Bat pattern
  4. Crab pattern
  5. Shark pattern
  6. Cypher pattern

Moreover, each of these structures has its own unique shape, Fibonacci ratios, and rules for identifying and trading the structure. While these patterns may be useful for analyzing financial markets, it is important to note that they should not be used in isolation. Yet, in conjunction with other technical analysis tools to confirm market trends and signals.
Let us describe each trading harmonic structure separately in both bullish and bearish markets.

Gartley structure

  • Bullish Gartley Pattern: It is a bullish reversal pattern that forms after a long downtrend. It consists of a series of price swings that create a bullish ABCD pattern. Then, it follows a retracement to the 0.618 key Fibonacci level. Finally, it moves higher to complete the pattern.
  • Bearish Gartley Pattern: It is a bearish reversal pattern that forms after an elongated uptrend. It consists of a series of price swings that create a bearish ABCD pattern. Then, it follows a retracement to the 0.618 key Fibonacci grade. Finally, it moves lower to complete the pattern.

Bat structure

  • Bullish Bat Pattern: This bullish reversal structure forms after a downtrend move. It builds by a series of price swings tracked by retracement levels of (0.382, 0.382, 1.618), (0.382, 0.886, 2.618), (0.5, 0.382, 1.618), or (0.5, 0.886, 2.618).
  • Bearish Bat Pattern: This bearish structure pattern forms after an uptrend move. It builds by a series of price swings tracked by retracement ratios of (38.2%, 38.2%, 161.8%), (38.2%, 88.6%, 261.8%), (50%, 38.2%, 161.8%), or (50%, 88.6%, 261.8%).

Butterfly structure

  • Bullish Butterfly Pattern: That bullish reversal structure shapes after a downward move and follows retracement levels of (0.786, 0.382, 1.618), or (0.786, 0.886, 2.618).
  • Bearish Butterfly Pattern: That bearish reversal structure develops after an upside movement and follows retracement ratios of (78.6%, 38.2%, 161.8%), or (78.6%, 88.6%, 261.8%).

Crab structure

  • Bullish Crab Pattern: A bullish reversal structure that develops after a downside movement and pursues retracement levels of (0.382, 0.382, 2.618), or (0.618, 0.886, 3.618) of the Fibonacci sequence.
  • Bearish Crab Pattern: A bearish reversal structure that shapes after an upward move and pursues retracement ratios of (38.2%, 0.38.2%, 261.8%), or (61.8%, 88.6%, 361.8%) of the Fibonacci succession.

Shark structure

  • Bullish Shark Pattern: it is a bullish reverse geometric structure that appears after a bear market. The final leg of the pattern is an extension of the BC leg, with a move that surpasses the X point.
  • Bearish Shark Pattern: it is a bearish reverse geometric structure that appears after a bull market. Also, it is considered a relatively rare pattern and requires strict adherence to its rules to confirm its validity.

Cypher structure

  • Bullish Cypher Pattern: In a bullish Cypher structure, the price will eventually make a new high and then reverse to the downside. The Cypher pattern is considered a relatively reliable pattern.
  • Bearish Cypher Pattern: In a bearish Cypher structure, the price will make a new low and then reverse to the upside. It can provide traders with good trading opportunities when used in combination with other technical analysis reversal tools.

What is the most profitable harmonic structure?

There is no one “most profitable” harmonic structure as each pattern has its own unique characteristics and distinct success rate. To explain, traders may prefer certain harmonic patterns over others. That is based on their personal experience and trading preferences. So, the profitability of a harmonic pattern depends on the trader’s ability to correctly identify the pattern and use it effectively within their own trading strategy.

in the next two sections, we will discuss further how to exactly identify and trade the best harmonic patterns in forex trading based on Fibonacci percentages.

What Fibonacci ratios are used in harmonic trading?

Harmonic trading patterns follow the Fibonacci sequence emanating from 61.8% and 161.8% ratios. To explain, Fibo retracements and extensions deliver traders with critical support and resistance levels. Below is a short description of retracements and extensions with projections also.


A retracement occurs when a price retraces a portion of a previous swing. This section might be expressed using Fibonacci ratios such as 0.38, 0.5, or 0.618.


Extensions occur when the price expands the previous swing by 100% and travels beyond the full swing. The extension swing can be 127% or 162% of the previous swings.


Projections occur when the price moves away from a completed retracement swing in the same (or greater) length as the original swing.

How to identify and trade Harmonic Patterns?

Identifying harmonic patterns involves a mixture of price action analysis and Fibonacci percentages. Here are simple steps to identify such patterns:

  • Step one: Pinpoint the potential harmonic pattern formation by looking for specific shapes on the chart. Once located, check if the pattern aligns with Fibonacci ratios and price action fundamentals.
  • Step two: Measure the pattern to determine if it falls within the specified range for that pattern type. Each harmonic pattern has specific measurements for each of its portions.
  • Step three: Check for confluence with other technical analysis tools, such as candle patterns, trendlines, or support and resistance grades to confirm the geometric structure’s success.
  • Step four: Initiate a Buying or selling trade with the completion of the Harmonic Pattern and its confirmation by other analytic tools.

It is important to cite that identifying harmonic patterns correctly needs practice and experience. It is also advised to use multiple timeframes to increase the accuracy of pattern identification.

Rules and techniques for utilizing Forex harmonic patterns

Rules and techniques are the same for all harmonic patterns in forex trading. Because they indicate potential reversal opportunities for traders and investors. As such, we will consider the most basic harmonic pattern to learn how to trade them in the currency market. That is to say, we will focus on the original Gartley pattern.

This harmonic formation has two key elements in its configuration. The AB=CD and the 61.8% retracement of XA swing towards the B level. The structure is formed when the point of action D is retraced into the XA swing. Yet, when D extends beyond X, the structure is no more a Gartley. In fact, it becomes either a Butterfly or a Crab extension patterns. Hence, the point of action D is usually formed from 78.6% to 88.6% of the XA swing.

Now, we will learn how to integrate harmonic patterns into a forex trading technique with details.

Bullish example

Considering the bullish harmonic pattern example from the NZDJPY D1 forex chart. From March 24 to April 26, 2023, NZDJPY
formed a bullish harmonic formation. The pair made a first higher high from the D grade, suggesting the success of the harmonic design.

Entry Rules

Traders may enter a long trade one tick above the bar high that confirms the pattern.

Stop Rules

The harmonic structure fails if the price closes below the first point X of the pattern. Hence, you can place your stop loss a few ticks below the lowest price of the X.

Target Rules

The first location of targets is the C and A price levels. The next objective is at elongations of 127% to 162% of the AD range starting from the D point level.

Bearish example

Regarding this bearish harmonic pattern example from the USDCAD W1 FX graph. From October 09, 2022, to March 05, 2023, USDCAD
created a bearish harmonic design. This pair made a first Lower-Low from the D grade, suggesting a successful harmonic formation.

Entry Rules

Investors can initiate a short trade one tick below the bar low that confirms the pattern.

Stop Rules

The harmonic design fails if the price closes above the first point X of the pattern. Therefore, you can set your stop loss a few ticks above the highest price of the X.

Target Rules

The initial price levels to be targeted are C and A. The second goal is to extend the AD range by 127% to 162% starting at the D level.

Advantages and Limitations

Harmonic patterns have a higher chance of success. But the main challenge in trading them is correctly spotting them on the chart using correct ratios. Actually, the major difficulty resides in identifying and drawing them correctly on the trading chart. In fact, each pattern has a unique shape and is formed by different Fibonacci ratios. Which makes memorizing all of them by heart almost impossible.


Precision is essential for all Forex harmonic patterns and trading in general. Since we reduce mistakes when we are as accurate as possible. The harmonic pattern PDF trading technique provides us with the best rules and chances of success. Note that using harmonic patterns in technical analysis, like any other trading approach, involves experience, dedication, and patience. So, harmonic patterns may be a powerful weapon in a trader’s arsenal if he properly understands the cheat sheet and applies them correctly.
