Gann Fan with Buy/Sell Signals

This Pine Script indicator is based on W.D. Gann's theory, specifically using Gann Fan lines to identify key relationships between price and time. It automatically detects a recent pivot low and draws multiple fan lines—such as 1x1 (45°), 2x1, 1x2, and others—from that point. These angles act as dynamic support and resistance levels. The script also provides buy and sell signals based on the 1x1 angle: a buy signal is triggered when price crosses above the 1x1 line, and a sell signal when it crosses below. For the most accurate results, this indicator works best on higher timeframes such as the 1-hour, 4-hour, or daily charts, where price movements are more stable and Gann's time-price relationships have better significance. This tool is ideal for swing traders and those looking to combine price action with geometric analysis.
