How the wheel turns into prices
On the Square of Nine, one full 360° turn adds exactly 2 to a price’s square root. Half a turn, 180°, adds 1; a quarter turn, 90°, adds 0.5; and 45° adds 0.25. From 100, whose square root is 10, the 90° level is 110.25, the 180° level 121 and the full turn 144 — and going the other way round, 64.
From a swing LOW the levels above are resistance; from a swing HIGH the levels below are support. The 360° and 180° levels are drawn strongest, the 90° cross next, then the 45° diagonals.
Using the Square of Nine
- 1Open Overlays → Squaring → Square of Nine. Its panel sets the step (30°, 45°, 90°, 120° or 180°), how many full turns to draw, and up, down or both.
- 2Click a swing low or high, or press ⚡ to place it on the last confirmed swing automatically; ◀ steps back to older swings.
- 3The same panel is a calculator: type any price and it lists one full turn of levels above and below it.

Questions
Why square roots?
Numbers on the Square of Nine spiral are arranged so that each ring adds a fixed amount to the square root. Moving round the wheel by an angle is therefore the same as adding to the square root and squaring again.
Which levels matter most?
Gann traders watch the full 360° turn and the 180° half turn most closely, then the 90° cardinal cross, then the 45° diagonals.
Does it work on any price?
Yes — the wheel works on any positive price, so the same tool reads a ₹50 stock, a ₹5,000 stock and an index.
