Orolo & W.D. Gann

Orolo & W.D. Gann is a remarkable historical study that traces the earliest documented evidence of William Delbert Gann’s scientific and metaphysical approach to market forecasting. This rare booklet uncovers the mysterious firm name OROLO, used by Gann in 1909 to advertise his revolutionary “Law of Vibration” before his legendary Ticker Interview. The research, compiled by the Gann Study Group, confirms that OROLO was not a pseudonym but a registered trade name directly linked to Gann’s office at 120 Liberty Street, New York, where he conducted his first experiments in predictive market science.

The text presents a full collection of Gann’s original OROLO advertisements from The New York Herald (April–November 1909), each demonstrating how he marketed his ability to forecast market movements using mathematical law rather than speculation or guesswork. These advertisements reveal Gann’s self-definition as a “scientific expert” on stocks, cotton, and grain — a man who claimed that “Vibration is the only theory that is practicable, based on natural law.”

Complementing these ads is a full reprint of The 1909 Ticker Interview, where Gann elaborates on how the “Law of Vibration” governs all market activity, linking it to physics, music, and cosmic harmonics. The booklet also includes an Afterword on the Ancients, connecting Gann’s thinking to Euclid, Pythagoras, and the timeless geometry of the universe. Readers witness how Gann’s fascination with mathematics, geometry, and time measurement (the “science of horology”) evolved into his later trading systems, such as geometric angles, proportion studies, and time cycles.

This document is essential reading for serious Gann students. It bridges history, geometry, and metaphysics — showing how Gann’s early writings already contained the seeds of his future discoveries, from The Tunnel Thru the Air to his Master Time Factor.
