How this is calculated

Level = (√price ± degrees/360)²

√24500.00 = 156.5248

The square of nine is a geometric construction, not a model of any market. It has no predictive validity that has been demonstrated under testing.

Gann Square of 9 Price Calculator: how it works

The Gann square of nine produces price levels by taking the square root of a price and adding fixed fractions. That is the entire method.

What the calculation does

Level = (√Price ± degrees ÷ 360)²

45° adds 0.125 to the square root
90° adds 0.25
180° adds 0.5

Taking the square root of the price, adding a fraction, and squaring the result generates a series of levels that widen as price rises. Traders using the technique treat these as potential support and resistance.

Worked example

Worked example · Price at 24,500

Given

  • Current price: 24,500

Working

  1. 1√24,500 = 156.525
  2. 245° above: (156.525 + 0.125)² = 24,539
  3. 390° above: (156.525 + 0.25)² = 24,578
  4. 445° below: (156.525 − 0.125)² = 24,461

Levels at 24,461, 24,539 and 24,578

What this is not

Levels of this kind sometimes appear to work for a reason unrelated to Gann: enough traders watch round numbers and common technical levels that behaviour clusters around them. That is a self-fulfilling effect in the short term, not a property of the market.

If you use it anyway

  • Position sizing and stop losses matter far more than entry levels.
  • Never risk capital you need, and never trade on borrowed money.
  • Derivatives magnify losses as readily as gains; the majority of retail derivative traders lose money.
  • A SEBI-registered adviser can give advice tailored to your circumstances; a calculator cannot.
