What is the Square of 9?
Gann Square of 9 analysis organises numbers around a central reference and studies angular relationships between price levels. This calculator uses a square-root approach: the angle in degrees is converted into a root offset, then squared back into a price.
It is a calculation aid, not a prediction engine. Use it with market structure, volatility, session context and independent trade management rules.
