How to Identify and Trade Harmonic Patterns
Harmonic chart patternsare a form of technical analysis that uses specific geometric relationships between price and time to identify potential reversal points in the market. These patterns are based on the idea that Fibonacci ratios correspond to critical areas of support and resistance.
When trading Forex, harmonic patterns can be used to find pin-point entries that have the potential to offer an excellent risk/reward balance. Harmonic stock patterns are also commonly used; in fact, these patterns originated in H.M Gartley’s 1932 book Profits in the Stock Market.
What Are Fibonacci Ratios?
Harmonic trading patternsuse the Fibonacci ratio, also referred to as the golden ratio. According to the Fibonacci sequence, each number following 0 and 1 equals the sum of the two previous numbers. This produces the following series: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, etc.
Each number is approximately 61.8% of the next number, then 38.2% of the following. It also produces complementary ratios of 23.6%, 50%, 78.6%, and 88.6%. When trading, these numbers are commonly expressed as decimals, like 0.618 or 0.382.
How to Identify Harmonic Patterns
Harmonic patterns can be identified in several ways. Some prefer to use a harmonic patterns indicator, which automatically shows patterns in a given market. Harmonic pattern indicators are useful for traders looking for a quick way to identify these patterns but are known to generate false signals.
Others use scanners, which survey the market for harmonic setups. How accurate is the harmonic scanner? That depends. A scanner’s accuracy is determined by its algorithm and it won’t be 100% precise. Ultimately, it’s always wise to manually verify opportunities presented by any market scanner.
Visually, harmonic patterns typically consist of five points (denoted by X, A, B, C, and D), four connecting lines, and three turning points. The first line linking X and A is the XA leg. The reversal of point A to point B forms the AB leg. Another retracement creates point C and generates the BC leg. Finally, point C leads to D, which is an entry point. This creates the bullish M or bearish W-shaped structures typical of these patterns.
The Top Harmonic Patterns for Forex Trading
Now that we have a basic understanding of harmonic patterns and how to identify them, it’s time to examine effective harmonic patterns for Forex trading. Note that the values won't always line up perfectly, so some slight variance is acceptable. Want to follow along?

The Gartley
The Gartley pattern was the pioneer when it comes to harmonic setups. It has two key conditions that must be met:
- B is a 0.618 retracement of XA.
- D is a 0.786 retracement of XA.
Additionally:
- The BC leg retraces AB by 0.382 to 0.886.
- The CD leg extends BC by 1.13 to 1.618.
With a bullish Gartley, traders typically set a buy order at D with a stop slightly below. For a bearish Gartley, they usually set a sell order at D with a stop slightly above. Profits are often taken at C.
The BAT
The BAT closely resembles the Gartley pattern. For a BAT to be valid, the following must be present:
- B retraces XA by 0.382 to 0.5.
- The BC leg retraces AB by 0.382 to 0.886.
- The CD leg extends AB by 1.618 to 2.618.
- D retraces XA by 0.886.
The strategy suggests traders set a buy or sell order at D, depending on whether the pattern is bullish or bearish, with a stop above or below X. You could use C as a key place to start taking profits.
The Butterfly
The Butterfly is another sibling of the Gartley, except that D exceeds X. The Butterfly requires that:
- B retraces XA by 0.786.
- BC retraces AB by 0.382 to 0.886.
- CD extends AB by 1.618 to 2.24.
- D extends XA by 1.27.
You could enter with a buy or sell order at D. Since D already extends X, stop loss placement with the Butterfly can be tricky. You may try using a 1.618 extension of the XA leg if you’re in doubt. Partial profits could be taken at C.
The Crab
The Crab is a favourite pattern for many traders because it has the potential to offer excellent risk/reward when correctly traded. It allows traders to enter at extreme highs and lows when:
- B retraces XA by 0.382 to 0.618.
- BC retraces AB by 0.382 to 0.886.
- CD extends AB by 2.618 to 3.618.
- D extends XA by 1.618.
As with the other patterns, D may be your entry point. Like the Butterfly, D already exceeds X, so you may need to get creative with the stop placement. You might set a stop at the 1.886 extension of the XA leg or use indicators to find an appropriate area. Given how far D extends XA, taking partial profits at B could be suitable.
