# Tools: Square of Nine

The Daily Price Lines tool can be used to plot Square of Nine lines on a chart.  Square of Nine values are derived from Gann's Square of Nine analysis.  Gann created a spiraling table of Prices that align at different angles.  Price values at each angle on the Square of Nine table can be plotted.  The primary Gann angles on the Square of Nine chart are 0, 45, 90, 135, 180, 225, 270, and 315.  The PyraPoint tool is similar to the Square of Nine lines.  However, the PyraPoint tool draws lines from a selected start point, whereas, the Square of Nine lines use Zero as the starting point.

To apply Square of Nine lines on a chart click the Daily Price Lines button on the Drawing Toolbar, and then click on the chart.  Right-click the mouse to open the Properties window and then configure the tool as shown below.

Appreciation is expressed to Greg Corbin for sharing this amazing chart of July Wheat showing the Gann Square of Nine levels marked on the chart.  Note how frequently the market turns on one of the 45 degree intervals on the Gann Square of Nine.

The Square of Nine is a spiral of numbers on a grid, starting with 1 in the center.  The spiral gets its name from the first inner square counting to nine.   The left side horizontal is known as the zero or 360 degree line.   90 degrees would be the prices that align vertically above the center point, and is measured clockwise from the zero line.

Example beginning of the Square of Nine number spiral:

31  32  33  34  35  36  37
30  13  14  15  16  17  38
29  12   3   4   5  18  39
28  11   2   1   6  19  40
27  10   9   8   7  20  41
26  25  24  23  22  21  42
49  48  47  46  45  44  43

The number series continues to spiral outward to ever increasing values.   Eventually the values shown on the chart are discovered on the Gann Square of Nine.  On the Square of Nine the number 2650 is on the 180 degree ray, and the number 2980 is on the 360 degree ray.
