Asia & London Session High/Low – EOD Segments (v4.5)

What it does

Plots the Asia and London session high & low each day.

When a session ends, its high/low are locked (non-repainting) and drawn as horizontal segments that auto-extend to the end of that same day (no infinite rays).

Optional labels show the exact level at session close.

Toggle whether to keep prior days on the chart or auto-clear them on the first bar of a new day.

Why traders use it

Quickly see overnight liquidity levels that often act as magnets or barriers during the U.S. session.

Map session range extremes for breakout/reversal planning, partials, and invalidation.

Works great alongside VWAP, 8/20/200 MAs, or your NY session tools to build confluence.

How it works

You define the session windows (defaults: Asia 00:00–06:00, London 07:00–11:00).

While a session is active, the script tracks running high/low.

On the bar after the session ends, the level is finalized and drawn; the segment’s right edge updates each bar until EOD, then stops automatically.

Inputs

Session Timezone: “Exchange”, UTC, or a specific region (set this to match your venue).

Asia / London Session: editable HHMM-HHMM windows.

Show Asia / Show London: enable either/both sessions.

Keep history: keep or auto-delete previous days.

Show labels: price labels at session close.

Colors & width: customize high/low colors and line width.

Best practices

Use on intraday timeframes (1–60m).

For equities/futures, set timezone to your exchange (e.g., America/New_York). For FX/crypto, pick what matches your workflow.

Common tweak: London 08:00–12:00 local; Asia 00:00–05:00 or your broker’s definition.

Notes

Non-repainting: levels only print once the session is complete.

Designed to be light and reliable—no boxes, just clean lines and labels.

If you want NY session levels, midlines (50%), anchored stop-time, or alerts on touches, this script can be extended.
