Session High/Low + Session Open

Session High/Low + Session Open

This indicator tracks the Asia, London, and New York trading sessions using Eastern Time and provides clear structural reference levels for intraday trading.

What It Does

1. Session High & Low Tracking

During each session, the script monitors price in real time.

It records the highest high and lowest low made within that session.

When the session ends, it prints a small horizontal “tick” at:

The final session high

The final session low

Each session uses a different color:

Asia → Yellow

London → Red

New York → Green

These ticks mark important liquidity levels that institutions often target in later sessions.

2. Market Open Vertical Lines (Toggleable)

Optional infinite vertical lines mark the exact open of each session.

Each session open matches its session color.

These lines extend infinitely up and down for clear time-based structure.

All session opens can be toggled individually or as a group.

3. Timezone
All sessions are calculated using Eastern Time (New York time) to ensure accurate alignment with global market structure.

4. Scale & Chart Compatibility
The indicator is designed to anchor directly to price so levels stay fixed to candles regardless of zooming, dragging, or scaling.

For Best Experience

For proper alignment and clean structure:

Pin the indicator to the same price scale as your candles (usually the right scale).

Avoid using multiple separate scales on the chart.

Use standard candles (not synthetic types like Heikin Ashi) for accurate session highs/lows.

Best used on intraday timeframes (1m–15m) for precision session analysis.

Keep your chart clean — these levels are meant to highlight liquidity, not clutter the screen.
