How To Use Gann Indicators In Stock Markets?

Last Updated: 3 Oct 2025

Gann indicators are normally considered to be a lot more about mathematics and less about charts and technicals. However, Gann indicators have been used quite extensively in identifying opportunities in the stock markets, both at the index level and the stock level. Let us first understand the concept of Gann and the logic behind the Gann indicators.

What is the basis of Gann theory?

The above square is called the Gann square or the Gann Master Chart and is the basis of Gann based trading. This is not a random chart but is the number system that is created through concentric squares. See where the number 1 starts right at the centre and then gradually that pattern is followed all the way up to 81 where the 9X9 square ends. While this has been depicted for just 81 squares, you can expand it to 144 squares and so on. Essentially, if you look at the pattern of the consecutive numbers, it forms a spiral all the way from 1 to 81 with each spiral forming concentric squares/circles. The logical movement from 1 to 81 is in a clock-wise fashion.

What are the benefits of using Gann Indicators in the Stock Market?

Gann indicators adorned by the legendary trader W.D. Gann are a series of time-established devices and methods applied in predicting price movements on the foundation of geometric angles, time cycles, and past price patterns. Such indicators may provide useful information to both short-term and long-term traders:

 Enhanced Market Timing

Gann numbers assist traders in differentiating the important time cycles, which are significant in determining the best time to buy or sell. Using the historical time intervals, traders are able to predict the possible turning point in the market, which will enhance the accuracy of timing and minimise emotional decision-making.

Price and Trend Forecasting

Gann techniques entail the extrapolation of future prices on geometric angles and historical price trends. There are tools such as the Gann angles used to predict the strength and direction of the market trends. Thus, traders have a predictive advantage during a bearish or bullish market.

Determining Support and Resistance

Traders are able to find important support and resistance areas with the assistance of such tools as the Gann Fan and Square of Nine. In most cases, these locations coincide with historical market tops or bottoms, and more specific trade entries and exits can be carried out on the basis of the historical price action.

Works Across All Timeframes

Gann indicators have one of their strengths in flexibility. Gann tools can be used to fit different trading styles and time frames. Whether a day trader is using 5-minute charts or an investor analysing monthly data, the structure will always be consistent.

Components of Gann charts

Gann charts are constructed based on price, time and geometry to predict market trends. These elements assist traders in determining important levels and when changes in the trends might occur.

Gann Fan

The Gann Fan is a series of diagonal lines, which are drawn at certain angles (such as 1×1, 1×2, 2×1) relative to a centre point. These lines serve as support and resistance levels, and they are dynamic so that they help identify the direction and strength of the trend.

Gann Angles

Gann Angles are mathematical instruments that indicate the correlation between price and time. The angle that is most valuable is the 1×1 (45-degree) angle, which is a representation of a balanced market. Angles steeper than 1×1 reflect the speeds at which the market moves faster or slower.

Square of Nine

It is a spiral diagram that predicts the future support and resistance levels through the historical prices. It is also useful in time-price co-location, which can be used to identify important reversal areas and areas of trend continuity.

Gann Wheel (Wheel of 24)

The Gann Wheel is a circular prediction instrument that incorporates both price and time and occasionally astrology. It is normally applied to trend forecasting in the long term and the determination of key market turning points.

Time Cycles

The Gann analysis relies on time cycles. Traders may find it easier to predict future trends, and this is through the observation of the recurrence of periods like 30 days, 60 days, 90 days, or 180 days, and be able to predict in advance when a trend will turn or increase in speed.

How to apply Gann Square in stock trading?

The Gann Square of 9 is simply a tool that calculates time and price besides calculating the square root of numbers, including the mid points. The Gann Square basically looks for price and time alignments and is often used to forecast prices. Typically, the time alignment is used for swing trading, while the price alignment is used for forecasting prices and also for identifying supports and resistances of a stock.

In the entire  enhanced Gann time-price squares indicator, it is the numbers on the cross and the diagonals that are really important from a forecasting point of view. For example, since the Gann Square is a perfect square it can also be represented as a circle that perfectly circumscribes the four corners of a square. Once that is done, the entire Gann Square is broken up into 8 equal parts of 45 degrees each. Since the circle has an angle of 360 degrees, each sector of 45 degrees will constitute one angle for the Gann Analysis. From a price and time forecasting point of view, the two most important lines are the Cardinal Cross and the Ordinal Cross. Let us focus on this Cardinal Cross and the Ordinal Cross more closely.

In the above Gann Square of 9X9 what are the important numbers from an analytical perspective? They are as follows:

• Numbers that represent 0 degrees or 360 degrees angle (2, 11, 28, 53)
• Numbers that represent 45 degrees angle (3, 13, 31, 57) Numbers that represent 90 degrees angle (4, 15, 34, 61) Numbers that represent 180 degrees angle (6, 19, 40, 69)

In the above chart, the blue lines represent the Cardinal Cross and the yellow lines represent the Ordinal Cross. They are next in importance and represent the important supports and resistance levels for stocks. Effectively, the numbers along the blue line (cardinal cross) represent the strong supports and resistances, while the numbers along the yellow line (ordinal cross) represent the strong supports, which are liable to be breached.

Some practical rules of W.D. Gann that can be applied

Gann trading has never been proven to be scientifically workable but the patterns and the harmony in numbers that Gann has spoken about do have a lot of resonance not only in mathematics but also in most sciences ranging from trading, architecture, design, etc.

If the high price or the low price of a stock or index is made on Friday (last trading of the week), the next week is likely to see higher highs and lower lows, respectively, through a stock trading app.

In a strong uptrend, weekly lows are normally achieved on Tuesday, while in a strong downtrend the weekly highs are achieved on Wednesday.

Four weeks (1 month approximately) is a good indicator of reliable breach. If a four week high is breached or if a four week low is breached then indications are of more highs or more lows, respectively.

There are certain basic ratios that are held. For example, if the price trend is up for 9 days at a stretch then it is likely to correct for 5 days at a stretch (Ratio of 9:5). Double bottoms and triple bottoms on a monthly chart after a minimum gap of 6 months is an indication of a fresh uptrend.

Similarly, double tops and triple tops on the monthly charts after a minimum gap of 6 months is an indication of a fresh downtrend.

Normally, 50% of the last selling price is the strong support area for a stock. If it goes below that price then it is not useful for investment.

In terms of application, Gann theory can be used to trace and interpret 3 kinds of distinct patterns. These include Time Study, Price Study and Pattern Study. While the applicability of the Gann approach by itself is doubtful, it is a very important step in understanding patterns in trading.

Conclusion

Gann indicators offer a unique mix of mathematics, time analysis and geometry to forecast stock market movements. They are useful for getting valuable insights into market timing and trend direction. Traders use tools like Gann Square, Fan, and Angles to align time and prices for strategic decisions. All in all, Gann’s method is relevant for those who are seeking a structured and disciplined approach to understanding the market cycles and patterns.
