Anyone who use this for trading? Not sure how to apply it. But it is the Diatonic scale? http://www.webtrading.com/gannarticle1.htm "I soon began to note the periodical recurrence of the rise and fall in stocks and commodities. This led me to conclude that natural law was the basis of market movements. I then decided to devote ten years of my life to the study of natural law as applicable to the speculative markets and to devote my best energies toward making speculation a profitable profession. After exhaustive researches and investigations of the known sciences, I discovered that the law of vibration enabled me to accurately determine the exact points at which stocks or commodities should rise and fall within a given time." The working out of this law determines the cause and predicts the effect long before the street is aware of either. Most speculators can testify to the fact that it is looking at the effect and ignoring the cause that has produced their losses. "It is impossible here to give an adequate idea of the law of vibrations as I apply it to the markets. However, the layman may be able to grasp some of the principles when I state that the law of vibration is the fundamental law upon which wireless telegraphy, wireless telephone and phonographs are based. Without the existence of this law the above inventions would have been impossible."
