[ICT Sebo] Session

Overview

This indicator visualizes the Asia, London and New York trading sessions and tracks each session’s high, low and midpoint in real time. It highlights key session phases and monitors how price interacts with prior session liquidity levels across subsequent sessions.

The script is designed as a session structure and liquidity context tool and does not generate trade signals.

How it works

The indicator uses a daylight-saving-time-aware New York timezone to ensure accurate session alignment throughout the year. Each trading session is defined by its start and end time and is highlighted directly on the chart.

During an active session, the script continuously updates the session high, session low and midpoint. These levels are extended forward into later sessions to observe how price reacts to previous session ranges.

For each session, the first third of its duration is calculated and visually highlighted, allowing traders to focus on early-session price behavior.

Session interaction logic

The indicator monitors when price touches or trades through highs and lows from previous sessions. For example, Asia session highs and lows are tracked during the London and New York sessions, and London session highs and lows are tracked during the New York session.

Once a session level is touched, it is locked and will not trigger repeated events.

Alerts

Alerts are generated when price touches a session high or low during a subsequent session. These alerts allow traders to monitor potential liquidity interactions without watching the chart continuously.

The following alert events are supported:

Asia session high or low touched during the London session
Asia session high or low touched during the New York session
London session high or low touched during the New York session

Alerts are triggered only once per level to avoid duplicate notifications.

Visualization

Each session is color-coded and displayed with a background highlight. Session highs, lows and midpoints are drawn as horizontal levels and extended forward for reference.

The first third of each session is highlighted with a shaded box to emphasize early-session structure.

Intended use

This tool supports session-based market analysis, liquidity mapping and time-of-day context evaluation. It is suitable for intraday analysis and should be used in combination with broader market context and risk management.

Notes

This indicator does not predict price direction, does not provide entry or exit signals and is intended purely as a visual and analytical reference.
