OPEN-SOURCE SCRIPT
Updated Sessions - New York, London & Asia
OVERVIEW
This indicator draws price range boxes for the main trading sessions (Asia, London/Europe, and New York) and an optional full-day box with daily high/low labels and open/close lines. It is a chart-context tool: it shows where price traded during each session window, not buy/sell signals.
PURPOSE / WHY THIS EXISTS
Many traders need a clear visual of:
1) which session produced the day’s high or low,
2) how large the session range was,
3) how sessions overlap (for example London–New York),
4) and where the daily open sits relative to those ranges.
This script combines three session range boxes with a daily structure layer (00:00–24:00 in a fixed timezone). The components are meant to work together so you can read session behavior against the same day’s overall range without stacking several separate scripts.
WHAT IT DOES
• Asia session box — tracks high/low while the Asia window is open; freezes the box when the session ends.
• London (Europe) session box — same logic for the London window.
• New York session box — same logic for the RTH-style New York window.
• Daily box — full calendar day high/low in the same timezone.
• Daily high/low labels — marks the bar time of the daily high and low.
• Optional daily open and close/last lines with labels.
Sessions are only drawn on intraday charts. On daily and higher timeframes, session boxes are disabled (the daily layer can still apply depending on your settings).
DEFAULT SESSION TIMES
All times use the America/New_York timezone (TradingView handles daylight saving for that zone). Defaults can be edited in the inputs:
• Asia: 20:00–05:00
• London (Europe): 03:00–12:00
• New York: 09:30–16:00
Overlaps are intentional. For example, Asia and London can share a morning window, and London and New York share a large mid-day window. The boxes stack so you can see concurrency visually.
HOW IT WORKS (CONCEPT)
1) Session membership
For each session, the script checks whether the current bar’s time falls inside the configured session string, evaluated in America/New_York.
2) Session start / end
• Session start: first bar that is inside the session after being outside.
• Session end: first bar that is outside the session after being inside.
3) Range tracking
While inside a session, the script updates running high and low from bar high/low. The live box left edge is the session start bar; the right edge follows the current bar. When the session ends, the box is fixed for that day/session instance and kept in an optional history list.
4) Daily layer
The daily open is taken from the 1D open of the symbol. Daily high/low are tracked from bar values until the New York calendar day changes, then the previous day is finalized as a historical daily box (if enabled).
5) Object limits
History depth is capped by internal safety limits so the chart does not exceed TradingView drawing object limits on low timeframes.
HOW TO USE IT
Typical workflow on a 1m–15m chart:
1) Load the symbol you trade (indices, FX, metals, etc.).
2) Keep default session times if your process is U.S.-anchored; otherwise edit the three session inputs.
3) Use GLOBAL visibility toggles if you only need one or two sessions on screen.
4) Compare the current New York (or London) box size to recent historical boxes of the same color — this is visual context for range expansion/contraction, not a trade rule by itself.
5) Use daily high/low labels to see whether extremes printed in Asia, London, or New York.
6) Use open/close lines if you track acceptance above/below the daily open as part of your own rules.
Suggested reading order on any day:
Daily structure first (open, D Hi, D Lo) → then session boxes → then your own entry method (structure, levels, etc.). This script does not define entries, stop-loss, or take-profit.
INPUTS (MAIN GROUPS)
• Session time strings and colors for Asia / London / New York.
• Per-session show historical vs current boxes; outline-only options.
• GLOBAL toggles for each session.
• Daily box: historical and current day display.
• Daily high/low labels and colors.
• Daily open/close lines and their labels.
COLORS (DEFAULT IDEA)
• Asia — yellow tones
• London — blue tones
• New York — red tones
• Daily — lime tones
Colors are customizable so you can match your chart theme.
WHAT THIS SCRIPT IS NOT
• Not a strategy and not a signal generator.
• Not a guarantee of profitable trades or future price direction.
• Not a replacement for risk management or a complete trading plan.
• Session times are conventions (liquidity-focused windows), not a claim that one session is inherently “better” to trade.
TIPS FOR A CLEAN CHART
• Publish/use with this script alone on the chart for clarity.
• Prefer outline-only if fills feel heavy.
• Reduce historical session display if the chart becomes crowded.
LIMITATIONS
• Session logic depends on the bar timeframe: on higher intraday TFs, box edges align to those bars, not tick-perfect open/close of the clock window.
• Some symbols have thin overnight liquidity; box size then reflects that microstructure, not “quality” of a setup.
• Past session ranges do not predict the next session’s range.
