The square root is 25.768 + 2 = 27.768^2 = 771 which is the number directly above 664 or one full 360 degree cycle out from center.

Example: Lets say that we are interested in the price 664 (which is in the vertical column straight up from the center). Basically, if you want to move around the coordinates on the Gann Wheel you take the number you are interested in ( such as the all time High or Low price) take the square root of the number, then add or subtract 2 from the root and re-square the result. Jenkins illustrates some interesting square root trading techniques utilizing the Square of 9 in his Gann Course and his book Chart Reading for Professional Traders. 10 through 25 completes the 2nd cycle, 26 through 49 completes the 3rd, etc… This particular arrangement of numbers creates a very unique square root relationship with other numbers on the chart. The rest of the numbers spiral around the center in a clockwise fashion to the number 9, which completes the first cycle of numbers around the center. The Square of 9 is basically a spiral of numbers starting with the number one in the center (or apex of the Great Pyramid) with the number 2 immediately to the left.

However, it is my personal belief that most traders are only using a few simple techniques and are not fully utilizing the true potential of this multidimensional Master Calculator. Many traders use this chart regularly as a primary trading tool.
