What is the Gann's Square?

Gann's Square is a tool used in financial analysis and technical charting. It is derived from the work of W.D. Gann, a famous trader and analyst from the early 20th century. Gann was known for his technical analysis techniques incorporating geometry, astrology, and numerology. He developed various methods for predicting price movements in stocks, commodities, and other financial instruments, and the "Square of 9" or "Gann Square" is one of his most well-known tools.

What is Gann's Square?

Gann's Square, sometimes called the "Square of 9," is a geometric representation of numbers in a spiral or square formation. It is used to find significant price levels, support/resistance points, and time cycles in financial markets. The underlying concept is that markets move in predictable patterns, and by understanding these patterns, traders can make better-informed decisions.

Key Components of Gann's Square


Spiral Arrangement: The Square consists of numbers arranged in a spiral pattern. The center is usually the number 1, and the numbers increase outward in a counterclockwise direction.

Angles and Geometry: Gann's Square uses angles and geometry to predict support/resistance levels. The key angles are typically 45 degrees (considered the "1x1" angle) and 90 degrees.

Horizontal and Diagonal Lines: These lines are drawn through key points on the Square to identify potential turning points in price movements.

How to Use Gann's Square on a Graphical Chart


  • Select a Reference Point: Choose a significant price level, such as a high, low, or closing price. This will be your reference point for creating the Square.
  • Gann's SquareConstruct the Square: Draw a square on the chart, starting with the reference point at the center or a specific corner. Extend the Square outward, following the spiral pattern.
  • Identify Key Angles and Lines: Draw lines at 45 degrees, 90 degrees, and other key angles to identify potential support/resistance levels. You can also use horizontal and diagonal lines to find intersections with price action.
  • Analyze Price Movements: Use the constructed Square to identify potential turning points, breakouts, or reversals. The angles and lines can act as support or resistance, providing clues about where the price might move next.
  • Combine with Other Technical Analysis Tools: Gann's Square is often used in conjunction with other technical analysis tools, such as trendlines, moving averages, or Fibonacci retracements. This combination can give a more comprehensive view of the market.

Practical Considerations


Complexity: Gann's Square can be complex, requiring significant practice and familiarity with Gann's methods. It's recommended that Gann's work be studied or software tools designed to implement his techniques be used.

Subjectivity: Interpreting Gann's Square involves some subjectivity. Different traders may draw and use the Square differently, so it's crucial to maintain a consistent approach.

Testing and Validation: Before using Gann's Square in live trading, test it on historical data and validate its effectiveness for your specific market and trading style.

Overall, Gann's Square is a unique and complex tool offering insights into market trends and price movements. However, it requires a deep understanding of Gann's methods and should be used cautiously and in conjunction with other technical analysis techniques.
