In 1937 Louise McWhirter published her ground-breaking forecasting methodology in which she revealed how to forecast in advance the general state of the economy for years to come. She revealed how to use planetary angles present at the time of a New Moon to identify key dates in a lunar cycle when the New York Stock Exchange would have a high probability of exhibiting a price trend change. She further showed how to use planetary transits, angles and aspects to predict times when individual stocks and commodity futures would have a high probability of exhibiting a price trend change. Today, McWhirter's work in in danger of fading into a distant memory. This book has been crafted in part to help ensure that does not happen. This book has also been crafted to assist the trader and investor in de-mystifying the many nuances in the McWhirter methodology.
