Gann Fans are a form of technical analysis developed by famed trader and analyst, William Delbert Gann. They are based on the premise that financial markets follow geometric and cyclical patterns. This method involves drawing diagonal lines at specific angles from a particular price point to predict future support and resistance levels.
The Geometric Basis of Gann Fans
Mathematical Foundation
The Gann Fan tool uses angles to represent the geometric nature of market movements. The primary angle is the 45-degree line, also known as the 1x1 angle, which represents one unit of price for one unit of time. The other commonly used angles include:
- 1x2 (26.25 degrees)
- 1x3 (18.75 degrees)
- 1x4 (15 degrees)
- 2x1 (63.75 degrees)
- 3x1 (71.25 degrees)
- 4x1 (75 degrees)
These angles are drawn from a specific peak or trough in the market.
Importance of Geometry in Markets
Gann believed that understanding these geometric relationships was crucial for predicting market behavior. He argued that markets move in predictable patterns, and these patterns can be identified and utilized for trading.
Cyclical Nature of Markets
Time Cycles
In addition to geometric angles, Gann fans also consider time cycles. The market is seen as moving in cycles of varying lengths, such as:
- Short-term cycles (days to weeks)
- Medium-term cycles (weeks to months)
- Long-term cycles (years to decades)
Historical Observations
Gann observed that certain time cycles frequently repeated in the market. He utilized historical data to identify these cycles, which helped him make predictive analyses.
Calculating Gann Fans
Step-by-Step Calculation
- Identify a significant high or low point: The starting point for the fan lines.
- Draw the 1x1 line: This serves as the baseline.
- Apply secondary angles: Draw additional lines at the pre-defined angles (e.g., 1x2, 1x3, 2x1, etc.) from the same significant point.
- Analyze the intersections: The points where price movements touch these fan lines indicate potential support and resistance levels.
Software Tools
Modern trading platforms come equipped with tools to automatically draw Gann Fans, simplifying the process significantly.
Application and Examples
Trading Strategies
Traders use Gann Fans to:
- Identify entry and exit points
- Determine the strength of a trend
- Predict potential reversals
Example Scenario
Consider a stock that has peaked. A trader may draw Gann Fans from this peak and use them to anticipate price movements. When the price nears the 1x1 angle and bounces back, it can be seen as a strong support level.

Frequently Asked Questions
What is the significance of the 1x1 angle in Gann Fans?
The 1x1 angle represents a perfect balance between time and price movements, indicating a 45-degree line on the chart. It is considered a strong indicator of future price movements.
Can Gann Fans be used in all financial markets?
Yes, Gann Fans can be applied to various markets, including stocks, forex, commodities, and cryptocurrencies.
How reliable are Gann Fans?
While Gann Fans have a historical basis and are used by many traders, no technical analysis tool is infallible. They are most effective when used in conjunction with other analysis methods.
Summary
Gann Fans offer a unique and historical approach to technical analysis, emphasizing the geometric and cyclical nature of markets. By understanding and applying these principles, traders can gain valuable insights into future market movements, enhancing their trading strategies.
