The Session Indicator is a charting tool designed to highlight key global trading sessions—London, New York, and Tokyo—directly on trading charts. It visually marks each session with optional shaded rectangles and plots session high and low price levels, with customizable line extension lengths. Users can view session data for the current day or multiple previous days, supporting analysis across various timeframes.

Key features include full customization of session start and end times, toggling of session rectangles, and control over how far high/low lines extend. The indicator works on all chart timeframes and helps traders identify volatility patterns associated with institutional trading sessions.

This tool aids in timing entries and exits around key liquidity zones, recognizing session highs and lows for breakout or reversal strategies, and visually distinguishing overlapping sessions such as London-New York. It supports markets including Forex, indices, and major symbols like NAS100. The indicator outputs visual signals based on market structure concepts and is suitable for traders employing reversal strategies.
