The Gann Square of Nine, often referred to as the "mystical square," is one of the most enigmatic and effective tools in the Gann trading arsenal. This unique calculator, which is based on a spiral of numbers, is used to identify potential support and resistance levels, as well as to forecast future market turning points with remarkable accuracy. While its origins are shrouded in mystery, the Square of Nine has been used by traders for decades to gain a deeper understanding of the hidden order and structure of the markets. This article will demystify the Gann Square of Nine, providing a practical guide to its construction and application.

Unveiling the Square of Nine

The Gann Square of Nine is a grid of numbers that spirals outwards from a central value. The numbers in the square are arranged in a specific pattern, with each number representing a potential support or resistance level. The square is constructed by taking the square root of a number, adding or subtracting a constant, and then squaring the result. The formula for this calculation is:

Output = (sqrt(Input) +/- Constant)^2

The constant used in this formula is typically 2, which corresponds to a 360-degree rotation on the square. By repeatedly applying this formula, we can generate a series of numbers that spiral outwards from the center of the square.

The Cardinal and Ordinal Crosses

Within the Square of Nine, there are two key patterns that are of particular importance to traders: the cardinal cross and the ordinal cross. The cardinal cross consists of the numbers that are aligned horizontally and vertically with the center of the square, while the ordinal cross consists of the numbers that are aligned diagonally. These two crosses represent the most significant support and resistance levels on the square.

Here is a table of the cardinal and ordinal cross numbers for a Square of Nine starting with the number 1:

RingCardinal CrossOrdinal Cross
12, 3, 4, 56, 7, 8, 9
210, 11, 12, 1314, 15, 16, 17

Trading with the Square of Nine: A Practical Example

To illustrate the practical application of the Square of Nine, let's consider a hypothetical trading scenario. Suppose we are analyzing the daily chart of a stock that has recently made a significant low of $25. We can use the Square of Nine to identify potential resistance levels and to forecast future turning points.

  1. Find the Starting Number: We begin by finding the number on the Square of Nine that is closest to the stock's low of $25. In this case, the number is 25.
  2. Identify the Cardinal and Ordinal Crosses: From the number 25, we can identify the cardinal and ordinal cross numbers. The cardinal cross numbers are 23, 27, 34, and 43, while the ordinal cross numbers are 21, 29, 38, and 48.
  3. Project Support and Resistance Levels: These cardinal and ordinal cross numbers now represent potential support and resistance levels for the stock. For example, if the stock rallies from its low of $25, it is likely to encounter resistance at the first ordinal cross number, which is $29.

Square of Nine in Action: A Case Study

Let's examine the price action of a hypothetical stock, ABC, over a 30-day period. The stock made a significant low of $49 on day 1.

DayPriceSquare of Nine Interaction
1$49.00Significant Low - Starting Point
10$57.00Price finds resistance at the first ordinal cross number (57)
20$65.00Price finds resistance at the first cardinal cross number (65)
30$81.00Price finds resistance at the 360-degree rotation of the starting number (81)

In this example, the Square of Nine provided a clear roadmap for the stock's price movements. By identifying the key resistance levels, a trader could have taken profits on a long position or initiated a short position at a favorable price.

Advanced Square of Nine Techniques

Beyond the basic application of the Square of Nine, there are several advanced techniques that can be used to enhance its effectiveness. These include:

  • Planetary Lines: Gann believed that the planets have a significant influence on the financial markets. By incorporating planetary lines into the Square of Nine, traders can identify even more precise turning points.
  • Time and Price Squaring: The Square of Nine can also be used to square time and price. By converting time into a price value, traders can identify dates when a significant change in trend is likely to occur.
  • Gannzilla Pro: For traders who want to take their Square of Nine analysis to the next level, there are specialized software programs like Gannzilla Pro that can automate the process of generating and analyzing the square.

Conclusion

The Gann Square of Nine is a effective and versatile tool that can be used to forecast market turning points with remarkable accuracy. By understanding the principles behind its construction and application, traders can gain a significant edge in their trading. While it takes time and practice to master, the rewards of incorporating the Square of Nine into your trading arsenal are well worth the effort.
