While the book is available free on line I prefer to hold it, underline it and carry it around. This is an introduction to the fact that groups on earth are influenced by the movements of the planets. While this is generally disregarded by most investors and traders. All who disregard it have not studied the subject. Even those that have studied the subject get it wrong as they do not have a background in trading. Those that follow Elliot wave will be surprised to see that there is a relationship with the planets. The greatest trader in history was an astrologer. W D Gann and his primary method of long term forcasting was astrology.
