W.D. Gann Theory

1. W.D. Gann Theory

William Delbert Gann (June 16, 1878 – June 24, 1949) was an American financial astrologer who developed financial techniques based on geometry, astrology, and mathematical principles. His theories are considered a form of technical analysis. While controversial and often shrouded in mystery, Gann’s work continues to influence traders and analysts today. This article provides a comprehensive introduction to W.D. Gann theory for beginners.

Introduction to Gann Theory

Gann’s approach to market analysis differed significantly from conventional methods of his time, and still stands apart from many modern approaches. He didn’t rely solely on price and volume charts. Instead, he integrated a complex system of tools and concepts, believing that time and price moved in specific cycles, angles, and geometric patterns. He believed these patterns were reflective of natural law and could be used to predict future market movements. His writings are often deliberately obscure, filled with coded language and symbolism, contributing to the ongoing debate and interpretation of his work.

Gann’s core belief was that markets are not random, but operate within a framework of mathematically and geometrically defined cycles. He sought to identify these cycles and use them to forecast price turning points. He often spoke of "natural laws" governing market behavior, drawing parallels between financial markets and the movements of celestial bodies. He didn't simply *predict* price; he aimed to understand the *why* behind price movements.

Core Concepts of Gann Theory

Several key concepts form the foundation of Gann's work. Understanding these is crucial to grasping the overall theory.

• Time Cycles: Gann placed immense importance on time. He believed that markets moved in cycles of varying lengths – 1 year, 5 years, 10 years, 20 years, and so on. He identified specific dates as potential turning points based on these cycles. He used various cyclical methods, including the Square of Nine (discussed below), to project future time cycles. These cycles aren't necessarily predictable with 100% accuracy, but Gann believed they significantly increased the probability of identifying key turning points. Time series analysis is a related field, though Gann’s approach was far more holistic.
• Price Cycles: While time cycles were primary, Gann also identified cycles in price movements. These cycles often corresponded to specific degrees of angularity and geometric shapes. Identifying these price cycles helps traders anticipate potential resistance and support levels. Fibonacci retracement is a related concept, although Gann’s methods are distinct.
• Angles: Gann's most famous tool is arguably his angles. He identified specific angles – 1x1 (45 degrees), 2x1 (67.5 degrees), 4x1 (75 degrees), and others – that he believed acted as lines of support and resistance. These angles are drawn from significant highs and lows on a chart. He used these angles to project potential future price targets. The 1x1 angle is often considered the most important, representing a balanced trend. Trend lines are a simpler, more common application of angles, but Gann’s angles are more specific and mathematically derived.
• Geometric Shapes: Gann believed that geometric shapes – squares, triangles, hexagons, and circles – played a crucial role in market movements. He often drew geometric patterns on charts to identify potential turning points. These shapes weren't simply aesthetic; he believed they represented underlying mathematical relationships governing market behavior. Elliott Wave Theory also utilizes patterns, but is based on crowd psychology rather than geometry.
• Square of Nine: This is a central tool in Gann's methodology. It’s a 9x9 grid used to project future time and price levels. Numbers are entered sequentially, and diagonals are drawn. The intersections of these diagonals and the numbers within the grid are believed to represent significant turning points. It’s a complex tool requiring dedicated study to master. Calendar spreads are a different form of time-based analysis.
• Hexagon: Gann also used hexagons extensively. He believed that the hexagon represented a natural balance and harmony, and that market movements often conformed to hexagonal patterns. The vertices of the hexagon were often used to identify potential support and resistance levels.

Gann Tools and Techniques

Several specific tools and techniques were developed and utilized by Gann.

• Gann Fans: These are a series of angles drawn from a significant high or low. They act as dynamic support and resistance levels. They are similar to trendlines but based on Gann’s specific angles. Moving averages can also act as dynamic support and resistance.
• Gann Grid: A grid overlaid on a chart, often based on the Square of Nine, to identify potential support and resistance levels.
• Cardinal Numbers: Gann emphasized the importance of certain numbers – 1, 2, 3, 4, 5, 6, 7, 8, 9, 12, 24, 36, 48, 60, 72, 90, 108, 144, 180, 216, 288, 360 – believing they held significant meaning in market cycles. These numbers often appear in time and price relationships.
• Astrology: Gann incorporated astrological principles into his analysis, believing planetary positions influenced market movements. This aspect of his work is highly controversial and often dismissed by mainstream analysts. Lunar cycles are sometimes examined in trading, though not with the same depth as Gann’s astrological approach.
• Retroactive Analysis: Gann often used retroactive analysis – applying his methods to past market data to demonstrate their effectiveness. This is a common practice in technical analysis, but it’s important to remember that past performance is not indicative of future results. Backtesting is a similar process used to evaluate trading strategies.
• Natural Numbers and Mathematical Sequences: Gann utilized natural numbers and mathematical sequences like the Fibonacci sequence, although his approach was different from the standard Fibonacci retracement used today. He believed these sequences were inherent in market structure. Chaos theory explores the unpredictable nature of complex systems, offering a contrasting perspective.

Applying Gann Theory in Practice

Applying Gann theory requires considerable study and practice. It’s not a simple “plug-and-play” system. Here's a general overview of how to approach it:

1. Identify Significant Highs and Lows: Begin by identifying key highs and lows on a chart. These will serve as the starting points for your analysis. Support and resistance levels are fundamental to this process. 2. Draw Gann Angles: Draw Gann angles (1x1, 2x1, 4x1, etc.) from these significant highs and lows. Observe how price reacts to these angles – does it find support or resistance? 3. Utilize the Square of Nine: Apply the Square of Nine to the chart, aligning it with significant highs and lows. Identify potential turning points based on the intersections of diagonals and numbers within the grid. 4. Look for Geometric Patterns: Scan the chart for geometric shapes – squares, triangles, hexagons – that may be forming. 5. Consider Time Cycles: Identify potential time cycles based on Gann's principles (1 year, 5 years, 10 years, etc.). Look for confluence between time cycles and price patterns. 6. Confirm with Other Indicators: Gann’s techniques are often used in conjunction with other technical indicators for confirmation. MACD, RSI, and Bollinger Bands are commonly used. 7. Manage Risk: As with any trading strategy, proper risk management is essential. Use stop-loss orders to limit potential losses. Position sizing is a key element of risk management.

Criticisms and Limitations

Gann theory has faced considerable criticism.

• Subjectivity: Many aspects of Gann's work are subjective, leaving room for interpretation. Different analysts may draw different conclusions from the same chart.
• Lack of Empirical Evidence: Critics argue that there’s limited empirical evidence to support the effectiveness of Gann's methods. Many claim his successes were due to luck or selective reporting.
• Complexity: Gann’s system is complex and requires significant time and effort to learn.
• Obscurity: His writings are often deliberately vague and difficult to understand, making it challenging to decipher his methods.
• Confirmation Bias: It’s easy to find patterns in data after the fact (hindsight bias). Critics argue that Gann’s successes were often attributed to patterns that were only apparent after they had already occurred.

Despite these criticisms, Gann’s work continues to fascinate traders and analysts. Many believe that his insights into market psychology and cyclical behavior remain relevant today. Behavioral finance explores the psychological factors that influence market decisions.
