The Square Spiral: The Mathematics of Markets 2nd Edition by Trevor Casey (https://bit.ly/2GftWa0)
This book demystifies the practice of time and price squaring and illustrates the use of these principles for trading success in the stock market. For decades people have tried to unlock the secrets behind the phenomenal success of stock market trader William Delbert Gann. Regarded as the Holy Grail of the stock market, the square spiral of the natural numbers helped Gann amass and subsequently lose a fortune – which was estimated at $50 million between 1910 and 1950. There have been many attempts to unravel the secret of how Gann made his money. What is known about his methods is that he used the ‘square of nine’ also known as the ‘Gann wheel’ to predict the time and price at turning points and was able, theoretically, to maximise profits from rises and falls in the market. Until now, there has been no credible explanation of his technique of using the square spiral to predict both the time and price of stocks at highs and lows in the market.
