What Is the Gann Square of 9?

The Gann Square of 9 is a mathematical spiral tool designed by William Delbert Gann (1878–1955), a trader who believed markets move in predictable geometric cycles rooted in square-root mathematics. The name comes from the 9-cell central square (1 at center, 2–9 around it) that forms the larger spiral grid.

In practice, you take a market price, apply the Gann spiral formula, and obtain price levels where the market is likely to pause, reverse, or break out. These become support, resistance, entry triggers, and stop-loss placements. Unlike moving averages or Fibonacci ratios, Gann Squares of 9 levels are derived purely from the current price, making them truly forward-looking reference points.

The Math and Formulas Behind the Gann Square of 9 Calculator

The calculator in this article uses the Grid-Snap Method — the approach used by leading Gann calculators for intraday trading. Here are all the formulas explained step by step.

Formula 1 — Base Anchor

base = floor( √(Price ÷ Pip) ) − 1

The base is one integer below the floor of the scaled square root. For price 24,250 with Pip 1: √24,250 = 155.7243, floor = 155, base = 154.

Formula 2 — Grid Center

Center = base² × Pip

For base = 154: Center = 154² = 23,716. This anchors the 7×7 spiral matrix.

Formula 3 — Spiral Cell Values

Cell [k] = (base + k × 0.125)² × Pip   [k = 0 to 24]

Each of the 25 highlighted cells adds k Gann steps (22.5° each) to the base, then squares it. The spiral winds outward: W → NW → N → NE → E → SE → S → SW per ring.

Formula 4 — Price Zone Snap Boundaries

sAbove = (floor(√(P/Pip) ÷ 0.125) + 1) × 0.125

sBelow = floor(√(P/Pip) ÷ 0.125) × 0.125

The input price always sits inside [sBelow², sAbove²]. For 24,250: sBelow = 155.625 → 24,219.14; sAbove = 155.75 → 24,258.06.

Formula 5 — Resistance Levels (R1 to R5)

R[n] = (sAbove + n × 0.125)² × Pip   [n = 1, 2, 3, 4, 5]

Five resistance levels radiate upward from sAbove. R1 is the immediate breakout level; R5 is the extended target.

Formula 6 — Support Levels (S1 to S5)

S[n] = (sBelow − n × 0.125)² × Pip   [n = 1, 2, 3, 4, 5]

Five support levels radiate downward from sBelow. S1 is the first breakdown level; S5 is the deepest target.

Why Is the Step Size 0.125?

Gann divided the full 360° circle into 8 equal parts (45° each). In the square-root domain where 360° = 1.0, one-eighth = 0.125. This 0.125-step creates progressively wider price intervals as prices increase — matching how real market volatility expands at higher prices.

Step-by-Step Guide: How to Use the Gann Square of 9 Calculator

1. Enter Market Price (LTP). Use the last traded price after the first 15–60 minutes of the session. Avoid using the exact opening price — early volatility can distort levels.
2. Select Pip Value. Use Pip = 1 for Indian indices (Nifty, Bank Nifty) and most stocks. Use 0.0001 for major forex pairs (EUR/USD, GBP/USD). Use 0.01 for JPY pairs.
3. Click Calculate. The spiral matrix, S/R table, and Long/Short trade entries are generated immediately— making this a truly automatic Gann calculator.
4. Read the Matrix Grid. The center cell is the base anchor (23,716 for price 24,250). Green cells are resistance levels; red cells are support. The gold cell shows exactly where your price sits in the spiral.
5. Use the S/R Table. R1–R5 are your five resistance targets. S1–S5 are five support levels. These are the primary trading reference points.
6. Execute the Trade Plan. Long when price breaks and closes above R1 with volume. Short when the price breaks below S1. Set stops at the opposite level.

A Fully Worked Example: Nifty 50 at 24,250

Input

Market Price = 24,250 | Pip Value = 1

Calculation Walkthrough

• √24,250 = 155.7243
• base = floor(155.7243) − 1 = 154
• Grid Center = 154² = 23,716
• sBelow = 155.625 → sBelow² = 24,219.14
• sAbove = 155.750 → sAbove² = 24,258.06

Price 24,250 is confirmed inside the zone [24,219.14 – 24,258.06].

Real Trading Scenarios

Scenario 1: Breakout Long — Bank Nifty

Bank Nifty consolidates at 52,300 for the first hour. A 15-minute candle closes above R1 at 52,420 with 40% above-average volume. Entry: above R1. Stop-loss: just below S1. Targets: R2, R3, R4 in sequence. Exit the full position at R4 or the end of the session.

Scenario 2: Support Bounce — Mid-Cap Stock

A liquid NSE stock sells off to exactly S3 with a hammer candlestick. VWAP and Gann S3 coincide — strong confluence. Enter long with stop below S4. Target R1 (previous session’s key level).

Scenario 3: Range-Bound Fade — Index

Nifty oscillates between R1 and S1 without breaking either level for three hours. Sell near R1, buy near S1, with tight stops. The automatic Gann calculator defines both boundaries precisely — no guesswork.

Scenario 4: Gann Calculator for Intraday Forex — EUR/USD

EUR/USD at 1.0850, Pip = 0.0001. R1 and S1 fall within 8 pips of the current price. London open breaks above R1 — enter long with stop at S1. Classic Gann breakout setup in a high-liquidity session.

Risk Management for Beginners: Stop-Loss and Targets

Rule 1 — Define Stop-Loss Before Entry

For a long trade above R1, stop-loss is placed just below S1. For a short below S1, the stop is just above R1. This ensures a defined maximum loss on every trade.

Rule 2 — The 1% Capital Rule

Never risk more than 1% of total capital on a single trade. Position size = Maximum Risk Amount ÷ Stop-Loss Distance (in points). For a ₹1,00,000 account with 1% risk and 80-point stop: max position = ₹1,000 ÷ 80 = 12 units.

Rule 3 — Minimum 1:2 Risk-to-Reward

Before entering, verify that Target 1 (R2 for longs, S2 for shorts) offers at least twice the risk. The calculator displays the Risk: Reward ratio automatically in the trade entries panel.

Rule 4 — Scale Out at Each Target

Book 30% at Target 1 and move the stop to break-even. Book another 30% at Target 2. Hold the final 40% for Targets 3 and 4. This strategy guarantees profit from every trend that reaches the first target.

Strengths and Weaknesses

Strengths

Frequently Asked Questions

What is the Gann Square of 9 calculator used for?

It generates intraday support and resistance levels, entry triggers, stop-losses, and profit targets from a single market price. It is used for Nifty, Bank Nifty, stocks, forex, and commodities.

Is there an advanced Gann Square of 9 calculator Excel free download?

Yes. Many traders build Excel versions in which entering a price automatically populates the entire S/R grid. Online calculators are faster for daily use; Excel is better for multi-symbol dashboards.

What Pip value should I use for Nifty 50?

Use Pip = 1 for Nifty 50, Bank Nifty, and most NSE stocks. Use 0.0001 for major forex pairs (EUR/USD, GBP/USD). Use 0.01 for JPY currency pairs.

How does this Gann calculator differ from standard pivot points?

Standard pivots use the previous day’s high, low, and close. The Gann Square of 9 uses only today’s current price and a square-root spiral, giving levels relevant to the session in progress — not the prior day’s range.

What does the center number in the Gann matrix mean?

The center is the base anchor value (base² × Pip). For a price of 24,250, the center is 23,716 (= 154²). The spiral builds outward from this point, and the current price appears as a highlighted cell showing exactly where it falls in the Gann cycle.

Can I use this as an automatic Gann calculator for multiple stocks?

Yes — run it for each symbol individually. For tracking many symbols at once, an Excel version is more practical.

Should I enter at R1 or wait for a confirmed breakout?

Always wait for a confirmed close above R1 on your trading timeframe (5-min or 15-min candle) with above-average volume. Touching R1 without a confirming close produces many false entries.

What is the best time frame for Gann intraday levels?

Enter the price 15–60 minutes after market open. Monitor levels on a 5-minute or 15-minute chart. The 15-minute chart filters opening noise while remaining granular enough for intraday entries.

Conclusion

The Gann Square of 9 calculator transforms a single market price into a complete intraday trading roadmap in seconds. Its precision, consistency, and cross-market applicability make it one of the most powerful free tools available to active traders. Apply the formula, track the levels daily, combine with volume analysis and price action, and you will develop a genuine, repeatable edge.

The calculator shows you where the market is likely to react. Your analysis tells you when and in which direction. Together, they form the foundation of a disciplined, structured approach to intraday trading.
