What is the ABCD Pattern?
The AB=CD or ABCD pattern was first identified by H.M Gartley and discussed in his 1935 book "Profits in the Stock Market." The pattern was further developed by legendary trader Scott Carney and Larry Pesaven and was featured in Carney’s various books on harmonic trading published from 1999 to 2010 where he discussed the ABCD pattern’s application in trading the financial markets.
Gartley’s and Carney’s research and contributions to technical analysis have greatly influenced the various harmonic pattern trading strategies that can readily be used by forex traders, including the ABCD pattern.
At its core, the ABCD pattern is a harmonic trading pattern based on theoretical elements that form part of Elliott Wave Theory. It can help forex traders who use technical analysis identify potential turning points in the market for a currency pair.
As shown in the following schematic diagram, the ABCD pattern is a geometric reversal pattern formed on exchange rate charts by four distinct exchange rate swings or legs. Each of the four legs of the ABCD pattern is represented by a letter in alphabetical sequence, hence the pattern’s name "ABCD."

The ABCD pattern follows a specific three-wave structure where the exchange rate initially forms a move from point A to point B, then it undergoes a retracement from point B to point C, which is followed by a move from point C to point D that equals the initial move from A to B.
As shown in the above diagram, the three legs that make up the ABCD pattern have internal measuring relationships that are closely related to the Fibonacci ratios that are derived from the Fibonacci number sequence. Technical traders who subscribe to Elliott Wave Theory often use Fibonacci retracement and extension levels to validate the existence of this pattern and determine potential exchange rate targets.
For example, Carney states that the C point of the ABCD pattern must retrace at least 38.2% or 0.382 of the AB leg to validate the pattern but no more than 88.6%. The length of the BC retracement leg is then projected in the same direction as the AB leg with the initial objective of the CD leg equal to the length of the AB leg, but he notes that CD leg lengths in the 1.13-2.618 region can be observed in practice.
Carney also observes that a 0.618 BC leg retracement of the AB leg will tend to result in a CD leg length on the order of a 1.618 BC leg length, while a 0.786 BC leg retracement of AB will typically result in a CD leg length meeting a 1.278 BC leg projection.
How to Identify the ABCD Pattern in Forex Trading
Identifying the ABCD pattern and using it in forex trading requires careful observation of exchange rate movements and a thorough understanding of the pattern's internal structure. In most cases, the AB leg of the pattern will be retraced substantially by the BC leg, while the final CD leg of the pattern will generally travel at least the length of the AB leg and often exceeds it.
Technical analysts using the ABCD pattern will typically go through a series of prudent steps to identify the pattern correctly that could be based on those detailed by Carney in his harmonic trading books. They include:
Step #1: Identify the Initial Move (AB Leg)
First look for a significant exchange rate move in the forex market that forms the AB leg. This move can be either bullish or bearish and should exhibit noticeable market momentum when it forms that can be confirmed by momentum oscillators like the Relative Strength Index (RSI). Traders can use various tools, including a visual inspection of the chart, Fibonacci retracement levels and pivot point analysis, to identify the starting point of the ABCD pattern.
Step #2: Spot the Retracement (BC Leg)
Once the AB leg of the ABCD pattern has been established, you can now seek to identify the BC retracement leg that follows. The BC leg should retrace a portion of the AB leg that will usually conform to one of the larger Fibonacci retracement levels of 0.618 or even 0.786. Traders can draw trendlines or use additional technical indicators to confirm that a reversal seems likely near such retracement levels to indicate that the BC leg may soon be concluding.
Step#3: Confirm the Continuation Move (CD Leg)
After the BC leg concludes, you will want to observe the forex market carefully to profit from a subsequent move in the opposite direction to the BC leg but in the same direction as the initial AB leg. The start of this move on decent momentum will confirm the pattern's final leg known as the CD leg. This leg will be in the same direction as the AB leg, and it should at least equate and typically extend beyond the AB leg in length. Forex traders can use market action analysis, volume indicators and other technical tools to validate that the move of the pattern’s CD leg is underway and that it seems likely to conclude near one of the typical Fibonacci extension levels computed from the length of the AB leg that can range from 1:1 to 1:2.618 in practice.
ABCD Pattern Rules
To ensure accurate identification of the ABCD pattern in forex trading, traders should adhere to the specific rules that have been developed by professional technical analysts to increase a trader’s success rate when using this increasingly popular chart pattern.
These rules serve as general guidelines for establishing the validity of the pattern and differentiating it from other possible market fluctuations that may not have the same expected outcome. The following rules apply to bearish and bullish ABCD patterns.
Rule #1
The AB leg of the pattern should be a significant and recognizable exchange rate move, exhibiting strong directional momentum. Traders can use trading alerts or custom indicators to identify potential ABCD patterns as they start forming based on the length and momentum of this initial AB leg.
Rule #2
The BC leg of the pattern should retrace a substantial portion of the initial AB leg and adhere to the larger Fibonacci retracement levels of 0.618 or 0.786. Traders can use Fibonacci retracement tools provided in their forex trading platform, or they can perform manual calculations to determine these target retracement levels accurately.
Rule #3
The CD leg should travel at least to the extent of the AB leg’s full length, and it will often move considerably beyond that to meet the classic Fibonacci projection or extension levels of 1.236, 1.382 and 1.618, even possibly moving as high as 2.618 of the length of the AB leg. The CD leg will also typically extend to 1.278 or 1.618 of the length of the BC leg in both exchange rate and time terms.
Rule #4
The length of the corrective BC leg should not exceed the length of the initial AB leg. This ensures that the pattern maintains its harmonic structure and does not deviate significantly from the expected exchange rate movements. This means that point C should never be below point A.
Rule #5
The D point of the ABCD pattern should align with the Fibonacci extension levels of the pattern’s initial AB leg. It acts as a potential profit-taking and pattern-completion target from which a subsequent reversal may occur. Traders can look for flag chart patterns or additional technical analysis tools to help confirm the level of the pattern’s D point.
How to Trade the ABCD Pattern in the Forex Market
Once the ABCD pattern is identified on the exchange rate chart of a currency pair trading in the forex market, traders can use it to identify potential trading opportunities and initiate trades. A step-by-step guide follows that consists of four basic steps that you can use to trade the ABCD pattern more successfully in the forex market.
Wait for the ABCD Pattern to Form
Patience is a key element of trading the ABCD pattern successfully. Remember to watch and wait until the BC leg completes its full retracement and indicators suggest that the exchange rate has now reached the C point of the pattern and is thus likely to reverse as the CD leg unfolds. This process helps ensure that the pattern’s trade setup has materialized before you enter a position based on it.
Confirm the ABCD Pattern with Other Indicators
Before entering a trade based on the ABCD pattern, remember to confirm the alignment of the pattern with other technical indicators. These can include moving averages, oscillators or support and resistance levels. This confirmation step helps validate the potential ABCD pattern trade setup and typically provides additional reliability to the trade signal the pattern generates.
Set Sensible Trade Entry and Exit Levels
Determine your trade entry level by placing a trade entry order near point C, which will involve buying or selling depending on the pattern's overall direction. Traders entering the market near C can set their targeted take profit points based on the standard CD extension levels to estimate where D is likely to occur while taking nearby resistance or support levels into account. To manage risk, you should set a stop-loss order to limit your potential losses if the market moves against your trade.
Monitor the ABCD Pattern Trade
Once the trade is executed, closely monitor the exchange rate movement and adjust your stop-loss and take-profit levels if necessary according to the procedures you have laid out in your trade plan. Consider trailing your stop-loss order to protect accrued profits if the market progresses in your favor. Continuously analyze the forex market using exchange rate charts and other technical indicators to stay informed about potential changes in the trend and market conditions.
Tips for ABCD Pattern Trading
Some tips intended to help you improve your experience when using an ABCD pattern trading strategy to trade forex include the following.
Tip #1: Combine the ABCD Pattern with Other Technical Analysis Tools
Use additional technical analysis tools, such as moving averages, momentum oscillators and volume indicators, to confirm the ABCD pattern's reliability and strengthen your trading decisions. This process can help you better validate your potential entry and exit point levels when using the pattern in practice.
Tip #2: Use Sound Risk and Money Management Methods
Implementing appropriate risk management strategies when trading the ABCD pattern makes sense. These can include setting stop-loss and take-profit orders in the market as well as watching the news and economic calendars closely for risk factors like major economic data releases. With respect to money management, you can protect your profits with trailing stops and use sensible position sizing techniques that help limit your exposure on any one trade to a fixed percentage of your trading capital. These prudent practices help protect your account from excessive losses and allow you to trade with greater discipline.
Tip #3: Backtest and Demo Trade Your ABCD Pattern Strategy
Before trading the ABCD pattern using real money in a live account, take the time to backtest your strategy using the pattern on historical exchange rate data and then practice trading it in a demo account using virtual money. This process allows you to evaluate its performance, identify potential limitations, become more confident about the strategy’s potential profitability and gain experience executing the trades the pattern sets up.
Can Forex Traders Benefit from Using the ABCD Pattern?
Forex traders can potentially benefit from incorporating the ABCD pattern into their trading strategies and plans. This pattern offers traders a systematic approach to identifying potential trend reversals and continuation opportunities, which can be invaluable in the dynamic forex market.
Since no forex trading strategy guarantees success, proper risk and money management methods should be applied. You will also want to continually refine your trading skills to maximize your chances of success when trading forex using the ABCD pattern.
Performing a broader analysis that takes into account other relevant factors can be helpful since the pattern is typically best used in conjunction with supportive technical analysis tools and a general review of potentially impactful fundamental information.
Overall, the ABCD pattern presents forex traders with a powerful tool for identifying potential opportunities to profit from trading currency pairs. By understanding the pattern's internal structure, adhering to its rules and incorporating it into an appropriate trading strategy, forex traders can improve the accuracy and profitability of the decisions they make when trading.
Frequently Asked Questions
When does pullback happen after the ABCD pattern?
An initial pullback occurs within the ABCD pattern to form its BC leg, and then another pullback typically occurs after the completion of the ABCD pattern. When trading the ABCD pattern, forex traders can use the BC leg pullback as an opportunity to enter into a trade with the expectation to profit from the upcoming CD leg move in the same direction as the initial AB leg move.
What is the ABCD pattern rule?
The rules that govern the ideal use of the ABCD pattern outline its expected structure and guidelines for identifying the pattern in a real-world situation. These rules include observing a significant initial exchange rate move known as the AB leg, then looking for a retracement that forms the BC leg and which adheres to specific Fibonacci retracement percentage levels of the initial move. Finally, traders aim to profit from the continuation move known as the CD leg that occurs in this pattern and that generally extends to and often beyond the AB leg in a way that conforms to standard Fibonacci extension levels.
Who invented the ABCD pattern?
The ABCD pattern was first identified and mentioned by H.M Gartley in his 1935 book “Profits in the Stock Market,” but it was later further popularized by the trader and author Scott Carney in his books on the subject of harmonic trading that discussed the ABCD pattern’s application in trading the financial markets.
