Overview

Three separate groups allow adjustment of pivot length to draw multiple horizontal lines at key levels and connecting trendlines on the price chart. Users configure colors and line styles for each group to highlight potential breakout zones and trend channels. The tool provides visual reference levels derived from pivot points without generating buy or sell signals.
