Someone has been asking me how to identify reversal points in the market. Honestly, relying solely on candlestick patterns and moving averages is far from enough. Recently, I’ve reorganized a framework for teaching harmonic patterns, and I want to share it with everyone.

Harmonic patterns do have a learning curve, but once you master them, the accuracy in identifying potential trading opportunities can reach 78.7%. That’s not a small number. I’ve seen many top traders use this method, but a lot of people think it’s too complicated and end up giving up.

Let’s start with the most basic one— the ABCD pattern. This is an entry-level pattern with three waves and four points, and the logic is very clear. After the impulsive wave AB, there’s a correction wave BC, and then another impulsive wave CD. With Fibonacci tools, the BC segment is precisely pinned to the 0.618 level, and the length of CD is the same as AB. Experienced traders will probe for positions near point C, or wait until the pattern fully completes and then enter from point D.

The next level up, with higher difficulty, is the Bat pattern and the Butterfly pattern. The Bat pattern was defined by Scott Carney in 2001, and compared with ABCD, it adds an extra X point. The key is that point B’s retracement must be at 50% of the XA wave. The extension of CD must reach at least 1.618 of BC, and it can go as high as 2.618. This kind of structure is especially effective for identifying potential reversal zones.

The Butterfly pattern, discovered by Bryce Gilmore, also uses a combination of Fibonacci ratios to find reversal points. Most importantly, it’s the 0.786 retracement of the XA segment, which helps you precisely locate point B.

Going further up is the Crab pattern, also a masterpiece by Scott Carney. The distinctive feature of this pattern is the 1.618 extension level of the XA wave, which helps confirm the potential reversal zone. The AB segment typically retraces between 38.2% and 61.8% of XA, while the BC segment projects to extreme points (2.618 to 3.618)—this is the range you should focus on. There’s also a variant called the Deep Crab, where point B’s retracement changes to 0.886, and the BC projection range becomes 2.24 to 3.618.

The Gartley pattern has two hard rules: point B must be 0.618 of XA, and point D must be 0.786 of XA. It’s a bit similar to the Bat pattern, but the rules are stricter.

The Shark pattern is a five-wave reversal pattern discovered by Scott Carney. To meet three Fibonacci conditions: the AB retracement is 1.13 to 1.618, the BC segment equals 113% of OX, and the CD segment is a 50% retracement of BC. This pattern is based on trading at point C, with point D as the take-profit.

Lastly, there’s the Three Drives pattern, which is especially rare because it requires perfect symmetry in both price and time. It consists of five points: three driving legs plus two retracement points. Drives 2 and 3 should extend to 127.2% or 161.8% of the A and C retracements, and the retracements are usually at 61.8% or 78.6%. Because the symmetry requirements are so high, I generally advise against trying to force it.

As for real-world application of harmonic pattern teaching, first figure out whether it’s bullish or bearish, then draw the pattern according to the Fibonacci rules for each structure. A bullish pattern means you can consider going long, while a bearish pattern means you should consider shorting.

To start using harmonic pattern trading, the first step is to spend time understanding the underlying theory. The second step is to determine your strategy direction. Only in the third step do you identify these patterns in the actual market. Don’t rush to get started—practice more on charts first and feel how these patterns perform under different market conditions.

Put simply, harmonic patterns use mathematics and ratios to predict reversal points in the market. Once you’ve mastered them, your trading will improve qualitatively. If you’re interested in studying deeper, you can find more case studies for comparison and repeatedly verify these rules. Let’s do it together!
