Session HL + Weekly HL

This indicator automatically plots the high and low levels from the Tokyo, London, and New York opening sessions, as well as the current and previous week’s high and low. Session levels are calculated from short, defined opening windows and extended forward to act as intraday reference levels. Weekly levels update in real time and persist across the chart.

These levels are commonly used to identify liquidity zones, support/resistance, and potential reaction areas during the trading day. Line style, colors, and the number of prior sessions displayed are fully customizable.
