W.D. Gann was an American trader (1878–1955) who developed mathematical tools for predicting stock prices. His Square of Nine is a spiral grid where each ring represents a 360° rotation around a central value. The key insight is that the square root of price is connected to price movement.
Root = √(Opening Price)
Resistance R1 = (Root + 0.25)² → 90°
Resistance R2 = (Root + 0.50)² → 180° (Key Level)
Support S1 = (Root − 0.25)² → 90°
Support S2 = (Root − 0.50)² → 180° (Key Level)
Pivot Points are mathematical support and resistance levels calculated using the previous trading day's High, Low, and Close. They are one of the most popular tools for intraday traders in India.
PP = (High + Low + Close) / 3
R1 = 2×PP − Low | S1 = 2×PP − High
R2 = PP + (H−L) | S2 = PP − (H−L)
Bank Nifty is the most liquid and volatile index in India. Daily movement of 300–800 points is normal. On high-volatility days it can move 1000–2000 points.
Before 9:00 AM: Calculate yesterday's Pivot Points (PP, R1, R2, S1, S2).
At 9:15 AM open: Enter Bank Nifty opening price in Gann S9 Calculator.
Find Confluence: Look for levels where Gann and Pivot are within 50–100 points. These are very strong zones.
Nifty 50 = 25 units | Bank Nifty = 15 units | Fin Nifty = 40 units
