Now the question arises, who was WD Gann? And why is he sought out even 60 years after his death? Let us find out.
William Delbert Gann, or WD Gann, was born on June 6, 1878. As a finance trader, he started his trading career in 1902 when he was 24. He developed numerous technical analysis tools, such as the WD Gann Angles, Circle of 360, Square of 9, Hexagon, and many others. Most of his works are based on astronomy, geometry, astrology, and ancient mathematics. Most of these were so powerful that they are widely used by traders even today. WD Gann’s theory on intraday trading is one of the most successful methods for day traders now.
Important Rules of WD Gann‘s Theory of Trading

Among the many indicators and technical tools, WD Gann laid down some basic rules to be followed for trading:
1. Friday Weekly High – Bullish Next Week
If the high price for the entire week is achieved on Friday, expect higher prices next week.
2. Friday Weekly Low – Bearish Next Week
If the low price for the entire week is achieved on Friday, expect a much lower price next week.
3.Tuesday Lows – Uptrend Marker
In a highly uptrending market weekly low is achieved on Tuesday.
4. Wednesday Highs—Downtrend Signal
If the market is in a strong downtrend (if the main trend is down), the weekly highs are generally achieved on Wednesday.
5. 4-Week High Breakout – Bullish Indication
When the price crosses the high of the last four weeks, it’s an advance indication of more higher prices.
6. 4-Week Low Breakdown – Bearish Indication
When the price breaches the low of the last four weeks, it’s an advance indication of more lower prices.
7. 30 DMA Breakdown – Trend Reversal Signal
In an up trending market, if the prices break the 30 DMA & remain below it at least for 2 consecutive days, it tells us of a much greater correction. (vice-versa)
8. 5:3 Rise-Correction – Probable Pullback
If the market rises for 5 consecutive days, there is a high probability that correction will be lasting for 3 days. (Ratio is 5:3)
9. 100% Rise Resistance – Strong Price Barrier
When the price starts rising from a particular level, Rs.100 or 100% rise whichever is earlier becomes a strong resistance.
10. 3-Day High Break – Fourth-Day Surge
When the price crosses the high of the last 3 days, it tells us about much higher prices on the 4th day. (Traders can buy it on the 4th day and place an SL order Rs. 3 below the last 3 days’ high) (vice-versa)
11. Deeper Correction – Trend Change Warning
If subsequent correction is greater than the previous correction, both in terms of price & time magnitude, this is an advanced indication that the trend is changing.
12. 50% Sell Zone – Critical Support Level
50% of the last highest selling Price is the strong support area. Any stock that is trading below this 50% level is not that useful for investment.
13. 9:5 Rise-Correction – Extended Pullback
If a price is rising for 9 consecutive day’s at a stretch, then there is a high probability of a correction for 5 consecutive days. (Ratio is 9:5)
14. Monthly Bottom Pattern – Mid-Term Opportunity
Don’t ignore a Double Bottom & Triple Bottom signal on a monthly chart, after a minimum gap of 6 months. ( advance indication for mid-term investment)
15. Monthly Top Pattern – Cautionary Signal
Don’t ignore a Double Top & Triple Top signal on a monthly chart, after a minimum gap of 6 months. (Not the right place for investment/entry, the price may fall)
16. Volume Spike Signal – Trend Reversal Hint
When the price is in a choppy phase, or in a consolidation phase, if a sudden volume spike is found there, it’s an advance indication that trend is likely to change.
17. Quarterly Breakout – Trend Reversal Alert
In a quarterly time frame, when a particular stock crosses the high or low of the last quarter (in the quarterly chart), it should be considered as an early indication that the underlying trend is trying to reverse.
