Gann Analysis

Gann Analysis is the system developed by W.D. Gann in the early 20th century, built around the premise that time and price move in geometric relationships. Angles like 1×1 (one price unit per one time unit), fans radiating from significant pivots at fixed angles, and numeric squares (most famously the Square of Nine) that produce price targets from calendar-date inputs. The framework is mathematically rigid and widely debated; proponents cite decades of consistent results, skeptics note that Gann's own records and the ambiguity of "calibration" make rigorous testing difficult.

The strategies in this category trade three Gann concepts with clearer rules. Gann 1×1 Angle trades bounces off and breaks through the primary diagonal line rising or falling at one price unit per one time unit from a significant swing. The "benchmark trend line" in Gann methodology. Gann Fan Trading uses the multi-angle fan (1×1, 1×2, 2×1, 1×4, 4×1) as a dynamic support/resistance grid, trading reversals at each angle. Gann Square of 9 generates horizontal price targets from the mathematical square-root arithmetic, typically used for take-profit placement. Gann analysis rewards specific instrument calibration. What works on a stock doesn't transfer cleanly to forex without recalibrating price-per-time units. Treat these strategies as geometric overlay systems that enhance other analyses, not as standalone methodologies.
