What is WD Gann theory?

WD Gann theory is a method of trading that is based on the idea that price movements in financial markets are not random, but rather follow predictable patterns. Gann believed that markets move in cycles and that these cycles can be predicted using mathematical calculations and geometric patterns. By understanding these patterns, traders can make more informed decisions about when to enter and exit trades.


History of Gann Theory

Background of W.D. Gann

William Delbert Gann, widely known as W.D. Gann, was an American trader and financial astrologer who was born in 1878 in Lufkin, Texas. Gann is considered to be one of the greatest traders in history and is known for his innovative trading methods and technical analysis tools. He started trading in 1902 and over the years developed a unique trading system based on mathematical calculations, geometry, and astrological principles.

Gann claimed that he was able to predict future market movements with remarkable accuracy using his trading methods, which he believed were based on natural laws and cycles. He wrote several books on trading and financial astrology, the most famous of which is "The Tunnel Thru the Air" published in 1927.

Development of Gann Theory

Gann's trading methods and theories were originally developed in the early 20th century and were mostly kept private. However, in the 1930s, Gann began to teach his trading techniques to a select group of students through seminars and courses. This led to the dissemination of Gann's theories and methods in the English language.

One of the key concepts in Gann Theory is the use of geometric angles and lines to predict market movements. Gann believed that price movements in financial markets follow certain geometric patterns and that by analyzing these patterns, traders can forecast future price movements.

Gann also developed several technical analysis tools, such as the Gann angles, Gann square of 9, and Gann fans, which are still widely used by traders today.


Key Principles of Gann Theory

Price and time analysis

According to Gann theory, price and time are the most important factors in analyzing the markets. Traders must pay attention to both price movements and the passage of time in order to make informed trading decisions.

Geometric angles

Gann believed that certain geometric angles, such as 45 degrees and 90 degrees, were significant in predicting future price movements. Traders can use these angles to identify potential support and resistance levels.

Square of nine

It is a mathematical tool used in Gann theory to predict future price levels. Traders can use this tool to forecast potential turning points in the market and identify key support and resistance levels.

Gann fan

The Gann fan is a technical analysis tool that is used to identify potential trendlines and support and resistance levels. By drawing multiple lines at different angles, traders can identify key price levels that are likely to influence future price movements.


Application of Gann Theory in Trading

Technical analysis

One of the key aspects of Gann theory is technical analysis, which involves studying past price movements and using this information to predict future price movements. Traders who use Gann theory will often use tools such as Gann angles, Gann fans, and Gann squares to identify key levels of support and resistance in the market.

Forecasting price movements

Another important aspect of Gann theory is forecasting price movements. By using mathematical calculations and geometric patterns, traders can predict when the market is likely to change direction or continue in its current trend. This can help traders make more accurate predictions about future price movements and make better trading decisions.

Identifying key levels

Gann theory also emphasizes the importance of identifying key levels in the market, such as support and resistance levels. These levels can act as barriers to price movements and can help traders determine when to enter or exit trades. By identifying these key levels, traders can better manage their risk and increase their chances of making profitable trades.

Criticisms of Gann Theory

Limitations of Gann Theory

While Gann theory has its proponents, it also has its critics. Some traders argue that Gann theory is too complex and difficult to understand, while others believe that its predictive power is overstated. It is important for traders to be aware of the limitations of Gann theory and to consider them when incorporating it into their trading strategy.

Challenges in applying Gann Theory

Another criticism of Gann theory is the challenges in applying its principles to real-world trading. Traders may struggle to accurately interpret the patterns and calculations of Gann theory, leading to inaccurate predictions and poor trading decisions. Overcoming these challenges requires dedication and practice, as well as a willingness to learn from both successes and failures.


Gann theory accuracy

While Gann theory has been around for over a century, its accuracy is still a topic of debate among traders.

Some traders swear by Gann theory and attribute their success to its principles, while others are more skeptical of its effectiveness.

Ultimately, the accuracy of Gann theory may depend on the skill and experience of the individual trader in applying its principles to their trading strategy.


Gann theory and Elliott wave theory comparison

  • Gann theory is based on the concept of cycles, while Elliott Wave Theory is based on the idea of fractals.
  • Gann theory is more focused on time frames, while Elliott Wave Theory is more focused on price movements.
  • Elliott Wave Theory is also more widely accepted by the scientific community.

So, here is question arise that which theory should you use?

Again, it comes down to your personal preference and trading style. Gann theory may be more suitable for those who prefer to trade based on time cycles and fluctuations, while Elliott Wave Theory may be more suitable for those who are more interested in analyzing trend patterns and price movements.

Ultimately, both theories can be effective, so it is important to do your own research and find the one that works best for you.



WD Gann theory is a timeless approach to trading that has been used by traders for over a century. By understanding the key concepts of Gann theory and how to apply them in trading, traders can improve their chances of success in the financial markets.

While Gann theory is not without its limitations and challenges, it remains a valuable tool for traders who are willing to put in the time and effort to master its principles.
