The Law of Cause and Effect

The Law of Cause and Effect: Creating a Planetary Price-Time Map of Market Action Through Sympathetic Resonance

Daniele Prandelli’s The Law of Cause and Effect represents a groundbreaking step in modern Gann research, focusing on the Planetary Price Line technique—one of W.D. Gann’s most enigmatic and least-documented methods. While Gann hinted at the relationship between planetary cycles and price-time dynamics, he left behind only partial references, such as his 1949 May Soybean chart. Prandelli builds on this legacy by reconstructing Gann’s hidden methods and introducing a practical conversion factor that allows planetary motion in degrees to be aligned with modern market price scales, from soybeans to the Dow Jones.

Part 1 lays the foundation by explaining the indispensability of discipline and the scientific rationale behind Gann’s planetary methods. It introduces key concepts such as planetary price lines, fixed planetary cycles, planetary aspects, and the Master Price Cycle. It also explores how to merge planetary price and planetary time to pinpoint market turning points.

Part 2 expands these techniques with real-time applications. Prandelli demonstrates live trades taken during the book’s writing, showing how he forecasted major reversals, including the 2007 Sub-Prime Mortgage top and the 2010 S&P 500 crash. Advanced sections present a new time system, cycle research, retracement critiques, and forecasting grids. Extensive appendices offer cycle origins, planetary data sources, software recommendations, and detailed ephemeris references, making this a complete working manual.

This book is a practical trading guide, merging astrology, geometry, and disciplined trade management. For advanced Gann students, it is an essential resource that finally lifts the veil on one of Gann’s most powerful yet hidden methods.
