ORB Sessions Markout is a chart indicator that automatically plots the Opening Range Breakout (ORB) boxes for the three major trading sessions: Asia, London, and New York. It visually highlights each session’s range with distinct colored boxes directly on the chart. Key features include dashed breakout extension lines extending to the session close, high and low price labels for each session, and full customization options for colors, session times, ORB duration, and opacity. Users can also control how many past days’ session ranges are displayed. This tool is designed to assist traders focusing on ICT, ORB, and session-based strategies by providing clear, automated session levels for support and resistance analysis.
