Sessions with OR is a trading indicator designed to visually represent key market sessions—Asia, London, and New York—on price charts with precise time alignment using broker-adjusted UTC offsets. It draws transparent, customizable session boxes that help traders identify time-based market structure and opening range (OR) dynamics. The indicator calculates the opening range for each session based on the initial minutes and extends it across the session width, with options for filled or outline-only boxes and separate color controls. Users can manually adjust session times, opacity levels, and toggle visibility and labels for each session and OR layer. It also supports multi-day lookback to display session structures over recent days. This tool is suitable for analyzing volatility windows, liquidity zones, and timing trade execution across various markets including Forex, indices, commodities, and stocks.
