WD Gann's discovery of the cycles that regularly appear in market movements enabled him to make some astonishing predictions and market forecasts. He provided information on only the minor cycles in his readily available stock and commodity courses.

He detailed how to apply the one year cycle which is familiar to traders using Gann's methods, although Gann did state that this was a minor cycle. Those that have used this cycle in their trading will know its predictive value and also its limitations. He left very little information on the other more powerful cycles. He stated to watch for turns in the 42 to 43 month. He did not detail how to determine the exact day of these reversals.

There are a number of cycles that culminate in the 41st to 43rd month that can be calculated to the exact day by using the most important cycles. By using these same cycles applied to "PRICE" exact price levels can also be known in advance at where a market is likely to reverse. What Gann did not make available in his courses was the information that is of most use. This information is not "secret" as it is revealed in other of his various works but in such a vague manner that it eludes all but the most thorough of examinations. There is much material available on WD Gann's methods. Most of it is fascinating and valid but the commonly known time and price alignments using the one year cycle, range divisions, square of nine, and squaring of time with price are only of minor value when compared to what was Gann's most useful method of determining market reversal points. The commercial promotion of this basic material has often been packaged as "mysterious" and "secret" and consequently has served to discredit his reputation when found lacking.
