W.D. Gann’s contribution to the investment community was the result of his dedication to the study of market history. In fact, he devoted years of his life to analyzing market price data in New York’s Astor Library. This is where Gann tested and proved his theories about history and began putting them to work in the markets.

During his 50-year career he made many spectacular projections, including his call of the 1929 high in the stock market. His remarkable success earned him the titles “The Guru of Wall Street” and “Master Economic Forecaster.” Gann’s tireless commitment to studying market price history led to his discovery of patterns, cycles and price formations that repeat in predictable and measurable ways. Two of Gann’s premier discoveries are the “Master Time Factor” and “Time Period Analysis.” In fact, market analysis based upon these two forecasting methods is unlike anything you have ever seen before, and yet it is mostly common sense.

In order for our research team to put Gann’s work to practice, one daunting requirement loomed. We had to acquire all of the historical data for every U.S. market in history.

Because computerized price data in the financial and commodity markets is only available since 1960 (dawn of the computer age), we set out to gather all price data for all U.S. markets as far back as the 1700’s. We searched high and low. Whether it was old newspapers, magazines or microfilm, we managed to collect all of the daily price data for every U.S. market.

It took 26 years and an investment of $250,000 to gather and computerize every daily price going back to the first day each market began trading. Thousands of man-hours and millions of keystrokes have resulted in a complete database of price history for all U.S. markets. To our knowledge it is the largest and only one of its kind.
