 This indicator is based on W. D. Gann's Square of 9 Chart and can be interpreted as the Gann Circle / Gann Wheel / 360 Degree Circle Chart or Square of the Circle Chart.

Spiral arrangement of numbers on the Square of 9 chart creates a very unique square root relationship amongst the numbers on the chart. If you take any number on the Square of 9 chart, take the square root of the number, then add 2 to the root and re-square it, resulting in one full 360 degree cycle (i.e. a 360 degree Circle) out from the center of the chart.

For example,
the square root of 121 = 11,
11 + 2 = 13,
and the square of 13 = 169

The number 169 is one full 360 degree cycle out (with reference to 121) from the center of the Square of 9 chart.

Similarly, if you take any number on the Square of 9 chart, take the square root of the number, then subtract 2 from the root and re-square it, resulting in one full 360 degree inward rotation towards the center of the chart.

For example,
the square root of 565 = 23.77,
23.77 - 2 = 21.77,
and the square of 21.77 = 473.93 (approximately equal to 474, which is directly below 565 on the Square of 9 chart)

The number 474 is one full 360 degree inward rotation (with reference to 565) towards the center of the chart.

How to Use this Indicator ?

This indicator is useful for finding coordinate squares on the Gann Circle that are making hard aspects to a previous position (such as a significant top or bottom) on the circle.

Input :

Swing Point (Significant price point, such as a top or a bottom)
Low / High ? (Is it a bottom or a top)
Number of Gann Levels (Number of Gann Cycles to be projected)

Output :

Gann Support or Resistance Levels (color coded as follows) :
Swing High or Swing Low (BLUE)
Support levels calculated with reference to the Swing High (RED)
Resistance levels calculated with reference to the Swing Low (LIME)
Release Notes: Usability changes. Configurable colors for Support, Resistance and Swing Level. Adjustable label position.
