Daily Separator & Killzone marker (L3J)

The “Daily Separator (L3J)” is a tool built for day traders who want a clean intraday structure around key U.S. market times and a professional trading-day model. It visually segments trading days, marks critical intraday timestamps (pre-market, cash open, killzone), and aligns with routines inspired by ICT concepts.
Important note: internal code comments and notes are written in French.

What the script does
- Draws clear, configurable vertical lines to separate each trading day.
- Supports two trading-day models:
- CME 18:00–17:00 (anchored on the Asian session, common for indices/futures)
- Calendar 00:00–23:59 (midnight-to-midnight) - Plots four key intraday rays in UTC‑4:
- 08:30 — U.S. pre-market open
- 09:30 — U.S. cash market open
- 09:50 — killzone start (per my routine)
- 10:30 — killzone end (per my routine) - Smart display logic: each day’s marker stays visible until the time is reached, then auto-hides to keep charts clean.
- Object-budget control: caps the number of historical separators to preserve performance.
Day trading strengths (ICT-friendly)
- Robust CME anchoring: day switches at the Asian session start in UTC‑4, which better reflects U.S. liquidity flow than calendar midnight.
- Focused killzone: highlights 09:50–10:30 for impulse setups, rebalancing, and liquidity events around the open.
- Clean readability: fully customizable colors, styles, and widths; markers auto-remove after their window.
Inputs (end‑user labels in French)
- - Timezone: choose the time zone (default UTC‑4) for session alignment.
- - Day separator:
- Day type: “CME 18:00–17:00” or “Calendrier 00:00–23:59”
- Color, style (solid, dashed, dotted), width
- Max number of visible separators (performance control) - Session (CME): Asian session window used as the anchor (default 18:00–16:00 UTC‑4)
- ndependent intraday markers:
- Pre‑Market Open 08:30
- Market Open 09:30
- Killzone Open 09:50
- Killzone Close 10:30 - - Each with show/hide, color, style, and width settings
Best practices
- U.S. indices (
ES1! ,
NQ1! ) and U.S. equities: favor the “CME 18:00–17:00” mode for a more liquidity‑centric read.
- ICT day trading: form directional bias around 09:30, execute between 09:50–10:30 as initial volatility structures.
- Multi‑timeframe use: keep it on execution charts (1–5 min) and context charts (15–60 min) for time alignment.
Technical notes
