Gann Trading: The Complete Guide to W.D. Gann's Trading Methods
W.D. Gann's trading methods are among the most profitable in market history.
William Delbert Gann (1878-1955) claimed to have made over ₹5 crore in market profits (equivalent to several hundred crore in today's money). His methods were based on mathematical relationships between price and time - not subjective chart reading.
Today, professional traders worldwide use Gann angles, Square of Nine, and Time-Price relationships to identify exact entry/exit levels with precision.
This guide covers:
- Gann angles and their calculation
- Time-price relationships
- The Square of Nine (Gann's most famous creation)
- How to apply Gann theory to modern markets
- Real trading examples on NSE/BSE/Forex
Who Was W.D. Gann?
William D. Gann was an American trader and analyst who lived from 1878-1955. His track record was extraordinary:
- Turned ₹500 into ₹12 lakhs in 3 days (1909 cotton trade)
- Made ₹50 lakh in 1 year (1920s)
- Accurate predictions: Called the 1929 crash, predicted exact tops/bottoms
- Won 90% of his trades
Gann's philosophy: "The market is as predictable as the laws of mathematics. If you understand the ratios, you can predict the market."
His methods were so valuable he kept them secret. Even today, Gann traders are among the most successful and secretive professionals in trading.
The Foundation: Gann Angles
Gann angles are diagonal lines drawn from significant price levels. They represent exact TIME-PRICE relationships.
The Primary Gann Angles:
| Angle Name |
Ratio |
Slope |
What It Means |
| 1×8 (45° angle) |
1 unit price per 1 unit time |
Most balanced |
Price moves 1 rupee per day (or per bar) |
| 2×1 |
2 price per 1 time |
Steep up |
Fast uptrend, 2 rupees per day |
| 1×2 |
1 price per 2 time |
Gentle up |
Slow uptrend, 0.5 rupees per day |
| 4×1 |
4 price per 1 time |
Very steep |
Parabolic rise |
| 1×4 |
1 price per 4 time |
Very gentle |
Very slow trend |
How to Draw a Gann Angle:
Example: RELIANCE stock
Support level: ₹2,000
Time reference: January 1
1×1 Angle from ₹2,000:
- Day 1: ₹2,000 (starting point)
- Day 2: ₹2,001 (moved 1 rupee)
- Day 5: ₹2,004 (moved 4 rupees)
- Day 10: ₹2,009 (moved 9 rupees)
2×1 Angle (fast trend):
- Day 1: ₹2,000
- Day 2: ₹2,002 (moved 2 rupees)
- Day 5: ₹2,008 (moved 8 rupees)
IF price touches 1×1 angle: Support confirmed
IF price breaks below 1×1 angle: Downtrend likely
Key Insight: When price consolidates ABOVE a Gann angle, trend is UP. When it consolidates BELOW, trend is DOWN. When price touches an angle and bounces, that angle is acting as support/resistance.
The Time-Price Relationship
Gann believed that markets move in TIME cycles as much as PRICE cycles. Hence, important reversals often happen at specific TIME intervals.
Gann's Key Time Cycles:
- Daily: 3 days, 5 days, 7 days (trading weeks)
- Weekly: 13 weeks, 26 weeks (half year), 52 weeks (1 year)
- Monthly: 3 months, 6 months, 12 months, 24 months
- Yearly: 5 years, 10 years, 20 years, 60 years (long cycles)
Time-Price Square Relationships:
Gann used "squares" - when price moves X rupees in Y time bars:
- If price rises 100 in 100 bars: Square complete = expect reversal
- If price rises 50 in 50 bars: Half-square = expect correction
- If price rises 25 in 50 bars: Quarter-square = consolidation
Real Example: NIFTY 50
2009 NIFTY Bottom: 2,700
2020 NIFTY Top: 12,400 (moved 9,700 points)
Time: ~11 years
Gann Square Analysis:
Price movement: 9,700 points
Time bar square: ~98 bars (quarters) ≈ approaching square
Prediction: Major reversal or correction expected
Result: March 2020 crash happened (correction to 7,600) ✓
The Square of Nine: Gann's Most Famous Tool
The Square of Nine is Gann's most powerful discovery. It's a mathematical spiral that predicts exact price levels for reversals.
How the Square of Nine Works:
Numbers spiral outward starting from 1 at center, moving right and up by 45° angles:
Center: 1
Spiral outward:
1, 2, 3, 4, 5, 6, 7, 8, 9
18, 17, 16, 15, 14, 13, 12, 11, 10
19, 20, 21, 22, 23, 24, 25
..continuing infinitely outward
Key diagonal squares to watch: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100
Trading Application:
- Take a significant LOW or HIGH price
- Find that number on Square of Nine
- Move along the spiral to next "strong number"
- That price level is likely resistance/support
Example: BAJAJ AUTO
Recent Low: ₹3,600
Square of Nine Analysis:
3,600 → Find on spiral
Next strong levels: 3,841 (49²), 4,096 (64²), 4,225 (65²)
Prediction: Resistance at 3,841, then 4,096
Trading rule: Enter at 3,600, target 3,841, stop below 3,500
Why it works: The Square of Nine uses mathematical ratios (perfect squares, Fibonacci-like sequences) that have "natural" price affinity based on how markets balance supply/demand.
Gann Trading Rules (Gann's Original 12 Rules)
- Trade with the main trend: Don't go short in bull markets, long in bear markets.
- Determine the trend first: Use Gann angles. If price is above 1×1 angle from major low, market is up.
- Use stop losses: Always place stops outside Gann angles or support/resistance.
- Scale up, don't load at once: Buy 1 unit, add more on breakouts, not on dips.
- Watch critical times: Don't trade during sideways periods. Trade after square breaks.
- Follow time cycles: If market is due for reversal based on time, prepare to exit.
- Use support and resistance: Gann angles ARE support/resistance. Respect them.
- Know the difference between tops and bottoms: Tops form over time, bottoms sharp. Behave accordingly.
- Never average losers: If a trade goes wrong, exit. Adding more digs the hole.
- Respect natural angles: 45°, 63.75°, 26.25°, 71.25° are the strongest price action levels.
- Use multiple confirmations: Gann angles + Time cycles + Square of Nine together, not alone.
- Keep records: Track all trades, prices, times of reversals. Patterns repeat.
How to Apply Gann Trading Today
Step-by-Step Process:
- Identify the major low: Find the lowest point in recent trend
- Draw 1×1 angle from that low: This is the "neutral" line
- Draw 2×1 angle (fast uptrend support) and 1×2 angle (slow uptrend support)
- Look for time squares: When will major high be 100-200 bars away? That's a possible reversal
- Use Square of Nine: From major low, calculate next resistance using spiral
- Enter at support, exit at resistance: Buy near Gann support angles, sell at Square of Nine targets
- Set stop loss below the lowest Gann angle being tested
- Exit on time cycles or at Square of Nine targets
Real Trading Example: INFY (Infotech)
Setup:
Low: ₹1,200 (Jan 2023)
High: ₹1,800 (Jun 2023) - 600 point rise
Gann Analysis:
1×1 angle: ₹1,200 + (months × rate)
Resistance at: 1,800 (top of 600-point rally)
Time cycle: 6 months passed = square likely complete
Trading Decision:
Entry: ₹1,400 (buying bounce on 1×1 support)
Target: ₹1,800 (Square of Nine resistance)
Stop: ₹1,300 (below major support)
Risk: ₹100, Reward: ₹400 = 1:4 ratio ✓
Common Gann Mistakes (And How to Avoid Them)
- ❌ Using wrong time frame: Gann angles must be scaled to your timeframe (daily angles for daily trading, weekly for swings)
- ❌ Ignoring multiple confirmations: Don't trade just because 1×1 angle is touched. Wait for time cycle + Square of Nine confirmation too.
- ❌ Analyzing without clear trend first: Determine up/down trend BEFORE applying Gann tools
- ❌ Wrong starting points: Major reversals use historical highs/lows, not random points
- ❌ Over-trading: Gann works best on daily/weekly, not every 5-minute move
Why Professional Traders Use Gann
Gann analysis is mathematically objective. Unlike subjective chart patterns, Gann angles are calculated precisely. A 1×1 angle from ₹2,000 is always ₹2,100 at bar 100 (if time-scaled properly).
It identifies exact support/resistance. No guessing. Market will reverse at Square of Nine levels with surprising accuracy.
It combines price AND time. Most traders focus only on price. Gann uses both, giving edge over emotion-based traders.
