W.D. Gann's trading courses are comprehensive collections of mathematical, geometric, and cyclical strategies designed to forecast market trends with high precision

Gann’s method stresses time as equally important to price: major reversals often occur when price reaches geometric levels at specific time intervals. Practical course components include constructing Gann angles and fans, using the Square of Nine to compute price targets and time projections, plotting median lines and trend channels, and applying cycle analysis (daily, weekly, and longer-term). Many courses mix historical case studies of commodity and stock moves with exercises to convert raw price series into Gann’s geometric frameworks.
