W. D. Gann Mathematical Formula for Market Predictions



W. D. GANN'S latest and greatest invention for predicting the trend on stocks and commodities.

WHAT IT DOES. This Calculator is made of plastic and can be laid over a chart and it is easier to see through it than through glass.

This Master Calculator shows what these time figures are and what they mean.

1. It shows. major and minor time periods.

2. Locates a TRUE TREND LINE and a RELATIVELY TRUE TREND LINE for an advancing and a declining market.

3. The main trend and the proportion in minor time periods in days, weeks, months and years.

4. The Price Resistant Levels are shown and a Price and Time Balance.

5. The different divisions for Time and Price.

6. The Master Time Cycles and their relation to price levels and the indication where on-e time cycle ends and a new cycle begins.

7. The Number Seven is mentioned more times in the Bible than any other number. The Master Calculator proves the importance of 7 in time periods, also 3, 9 and 12 which are referred to in the Bible. This Calculator accurately measures Price Time and Space for future indications of Time Trends.,

8.             The Master Calculator locates the Corner Stone, the Key Stone and the Cap Stone for price and time Trend. It proves the Master Number and Master Time Cycle and shows why and how they work on price.

9. The Master Calculator proves 9 divisions of time from one center or time factor and shows at a glance whether the price of stocks or commodities are in a weak or strong position.


The Value of Master Calculator to You

It is absolutely mathematically accurate and prevents you from making mistakes on price or time trend. It eliminates human judgment and guesswork and saves at least 75% of the time required to calculate trend indications. This is of great value to people who are busy and whose time is valuable.

One job of research covering a period of 150 years required one man three weeks to complete. The Master Calculator covered the whole calculation in three hours time and did not make one error. The man who did the research work averaged one error for every three years.

W. D. GANN has devoted over 52 years to research work on stocks and commodities and has spent a fortune to complete this revolutionary discovery.

The value of this Master Calculator to you cannot be measured in dollars. You have the use of it for your entire lifetime.

You receive with the Master Calculator complete written rules and instructions on how to use it.

We now have two (2) Master Calculators ... Numbers 9 and 12. With these you can calculate quickly and accurately all future TIME CYCLES, PRICE and TIME RESISTANCE LEVELS. The new discovery used in connection with this Calculator forecast the big advance in Soy Beans from August 20, 1953, to March, 1954; also predicted that Coffee would advance to the highest prices in history in 1954. These Calculators gave these indications, based on the Master Time Cycle, as related to price.

One man who bought the Master Calculator says: "It is the greatest invention since the wheel. It saves me time and makes profits."

A cotton trader says: "I first took your course in 1927, and it has been of great value to me; but your new Master Calculator is the greatest discovery you have ever made, and the most valuable. It indicated top for March coffee on at 4020 on September 8, 1952, and called for low at 3210 on January 12, 1953. March cotton sold at 3212 on January 12. That is plenty close for me."

The price of the Master Mathematical Calculator depends upon what courses you take in connection with it. It can be used on any commodity or, on stock averages or individual stocks.

The Master Calculator can only be used with the Master Courses. It is not sold separate from the courses and cannot be used with the Mechanical Method.

We are making a special price to students who have taken the Master Courses on Stocks and Commodities. Please write if you are interested in the Master Calculator as we are having a supply made up and will reserve one for you.
