Gartley Harmonic Pattern Example: Cipher Pattern

### Harmonics – Gartley Geometry

I believe we should be calling these patterns Carney Harmonics or Gilmore Harmonics because Gartley never gave a name any designs – the genius work Bryce Gilmore and Scott Carney did that in his various Harmonic Trader series books. Scott Carney is the man who discovered and named a great many patterns and shapes that we see today. And Carney’s work is some of the most developed and contemporary work of Gann’s and Gartley’s that exists today. But the understanding and application of Carney’s and Gilmore’s patterns have been woefully implemented by many in the trading community. Any of you reading this section or who were drawn to it because of the words ‘harmonic’ or ‘Gartley’ must do two things before you would ever implement this advanced analysis into any trading plan:

1. Read Profits in the Stock Market by H.M. Gartley – this is the foundation of learning and identifying harmonic ratios.

There are a series of other works by expert analysts and traders that address Gartley’s work and are worth reading, such as Pesavento, Bayer, Brown, Garrett, and Bulkowski. Do not consider their work merely supplementary – I find their work necessary to fully grasp the rabbit hole you are attempting to go down. Harmonic Patterns are an extremely in-depth form of analysis that encompasses multiple esoteric and contemporary areas of technical analysis. If you think finding the patterns and being able to draw them is sufficient to make a trading plan, you will lose a lot of money. Additionally, some words of wisdom from the great Larry Pesavento: An understanding of harmonics requires an in-depth knowledge of Fibonacci.

### Harmonic Geometry, in a nutshell

In a nutshell, Harmonic Geometry is a study and analysis of how markets move and flow as a measure of proportion from prior price levels. These proportional levels are measured using Fibonacci retracements and extensions. When these patterns (triangles) complete, they create powerful reversal opportunities. Carney calls the end of these patterns PRZs – Potential Reversal Zones. The significant error that many new traders and analysts make when they find a complete pattern is the same problem many new traders make with any new tool, strategy, or method: they don’t confirm. Make no mistake: Harmonic Patterns are powerful. But like any analysis or tool, it is not sufficient to take a trade. Harmonic Pattern analysis is just one tool in your trading toolbox. And like any toolbox, you need multiple tools to tackle the various projects and goals you want to achieve.

Contrary to popular belief, Gartley did not utilize Fibonacci levels or ratios in his work. Nonetheless, harmonic ratios are based on three classifications of harmonic ratios: Primary Ratios, Primary Derived Ratios and, Complementary Derived Ratios. As you develop a further understanding of the various patterns and their ratios, you will come to appreciate the very defined structure of this type of technical analysis.

Primary Ratios

• 61.8% = Primary Ratio
• 161.8% = Primary Projection Ratios

Primary Derived Ratios

• 78.6% = Square root of 0.618
• 88.6% = Fourth root of 0.618 or Square root of 0.786
• 113% = Fourth root of 1.618 or Square root of 1.27
• 127% = Square root of 1.618

Complementary Derived Ratios

• 38.2% = (1-0.618) or 0.618 squared
• 50% = 0.707 squared
• 70.7% = Square root of 0.50
• 141% = Square root of 2.0
• 200% = 1 + 1
• 224% = Square root of 5
• 261.8% = 1.618 squared
• 314% = Pi
• 361.8% = 1 + 2.618

### Elliot Wave and Harmonic Geometry

Ellioticians are very aware of the strong connectedness that Gartley’s and Carney’s work has within Elliot Wave Theory. There are significant elements between the two types of technical analyses that create a mutual symbiosis. However, while they are very similar, it is crucial to understand that there are some significant differences between the two.

 Elliot Gartley Dynamic, Flexible. Static, Definite. Wave counts are more fluidly labeled. Each move is labeled either XA, AB, BC, or CD. Many variations and intepretations No variation permitted. Wave alignment varied and malleable. Each price point alignment must be exact.

The combination of Elliot and Gartley is powerful, and Gartley Harmonics can help confirm Elliot Waves. The following articles will describe, in further detail, specific Harmonic Patterns.
