Cập nhật Previous session High/Low – Asia London USA

Overview
This indicator automatically plots the Previous Day’s (PD) session Highs and Lows for the Asia (Tokyo), London, and USA (New York) trading sessions.
Each session is color-coded for clarity:
🟩 Asia (Green)
🟥 London (Red)
🟦 USA (Blue)
At the close of each session, the indicator records that session’s high and low, draws horizontal lines across the chart, and labels them neatly in the center of each range — above the high and below the low for perfect visual balance.
⚙️ How It Works
The script continuously tracks the current high and low within each session.
When a session closes, those values are locked in as the PD High and PD Low.
Clean lines and centered labels are drawn immediately.
The labels automatically offset slightly above or below the line to avoid overlap, with user-controlled spacing.
This helps traders quickly identify where price interacts with the previous session’s structure, a core concept for many session-based and liquidity-based strategies.
🧭 Sessions and Timezones
Each market session runs in its native timezone, so you can align them perfectly to your chart or your preferred trading hours:
Asia Session: Default 08:30 – 11:00 (Australia/Adelaide time)
London Session: Default 08:00 – 10:00 (Europe/London)
USA Session: Default 09:30 – 16:00 (America/New_York)
You can change each session’s hours and timezone from the Inputs panel.
🎨 Customization
In the Inputs menu you can:
Toggle each session on or off
Choose line color and thickness
Enable or disable labels
Adjust vertical offset (ticks) for label spacing
“High label offset” – moves label further above the high line
“Low label offset” – moves label further below the low line
These adjustments make it easy to keep charts clean and readable on any instrument or timeframe.
📈 Practical Use
This indicator is ideal for:
Session traders who mark PD Highs/Lows as liquidity zones
London or NY session scalpers who watch for breakouts, fakeouts, or reversals
ICT / Smart Money Concepts users wanting automatic session reference levels
Anyone wanting a quick visual map of inter-session structure
