Gann Fan / Gann Square

Overview

Gann Fan and Gann Square tools use geometric angles based on W.D. Gann's time-and-price equilibrium theories to project support, resistance, and potential reversal zones into the future. These tools are favoured by advanced stock and forex traders who incorporate time analysis. Explore Gann tools on TradingView and compare with Fibonacci methods in our indicator guide library.

How It Works

The Gann Fan draws lines at geometric angles (1×1, 1×2, 2×1, etc.) from a significant swing point, where 1×1 represents one unit of price per one unit of time. The Gann Square maps price-time relationships into a grid. The 1×1 (45°) line is considered the most important — price above it is bullish, below is bearish.

Key Signals

• Price above the 1×1 Gann angle = bullish trend supported by time-price equilibrium.
• Price breaking below the 1×1 angle = potential bearish shift.
• Support or resistance at Gann square levels validates the geometric framework.
• Intersections of multiple Gann angles create high-probability reversal clusters.

Common Mistakes

• Not scaling the chart correctly — Gann angles require proper price-time ratio calibration.
• Applying Gann tools without understanding the underlying mathematical theory.
• Over-relying on Gann geometry without confirming with price action or volume.
