SessionOpiningRange is a cTrader indicator that automatically plots the Opening Range High and Low for the Tokyo, London, and New York trading sessions on any chart and timeframe. It calculates these key levels in real time based on configurable session start times and opening range durations (default 15 minutes). Each session is independently customizable with unique start times, colors, and toggles. The indicator displays clear horizontal lines marking the session highs and lows, which serve as important breakout and reversal reference points. An optional background fill highlights the Opening Range zone for quick visual identification, and session labels can be enabled to indicate which session is displayed. This tool supports multiple instruments including Forex, Gold, Indices, and Crypto. It is designed for traders using ICT/SMC concepts, Opening Range Breakout strategies, session-based liquidity analysis, and prop firm trading requiring clear session structure. Compatible with all timeframes from M1 to W1 on cTrader for Windows and Mac, it is implemented in C# (cAlgo). Default session start times are set to Tokyo 01:00, London 09:00, and New York 14:30 (UTC+1), all adjustable to match broker timezones.
