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 for intraday usage.
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.
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. If we further divide the circle in eight equal parts of 45 degree each, following intermediate resistance levels (ascending) would be generated:
127 (45 degree)
133 (90 degree)
139 (135 degree)
145 (180 degree)
151 (225 degree)
157 (270 degree)
163 (315 degree)
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.
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. If we further divide the circle in eight equal parts of 45 degree each, following intermediate support levels (descending) would be generated:
553 (45 degree)
541 (90 degree)
529 (135 degree)
518 (180 degree)
507 (225 degree)
496 (270 degree)
485 (315 degree)
How to Use this Indicator ?
This indicator is designed to generate Circle Intraday Levels based on HIGH and LOW of the opening bar for the day. You may use the bar interval (1 minute, 3 minutes, 5 minutes, 15 minutes etc.) which is suitable for the underlying instrument. lines for the day would be generated only after confirmation of the opening bar of the day.
Gann Support or Resistance Levels:
- HIGH and LOW of the Opening bar for the day (dashed BLUE lines)
- Support levels calculated with reference to the HIGH of the opening bar
- Resistance levels calculated with reference to the LOW of the opening bar
