Updated UK Dual-Session Highlighter
Overview
This indicator is a specialized volatility-window tool designed for traders operating in UK Time (Europe/London). It specifically isolates the two highest-probability trading windows for the Nasdaq (NQ) and other US/European indices, while intentionally leaving the "Lunch Lull" period unhighlighted to help traders avoid low-liquidity "chop."
The Dual-Session Strategy
The script highlights two distinct phases of the trading day:
London Morning (09:15 – 12:00): Captures the core European institutional flow and the establishment of the morning trend.
The US Active Window (13:30 – 17:15): Covers the critical 13:30 US Economic Data releases, the 14:30 New York Open, and the high-volume London-NY Overlap.
Key Features for 2026
Timezone Locked: Hard-coded to Europe/London. You do not need to adjust your chart settings; the indicator stays accurate regardless of your local time.
Automatic DST Handling: Fully compatible with 2026 Daylight Saving transitions (GMT/BST). It automatically adjusts when the UK clocks change in March and October.
The "Lunch Lull" Filter: By leaving the 12:00–13:30 window blank, the indicator provides a visual "stop" signal during the period when London traders are at lunch and US pre-market volume is typically at its lowest.
Fully Customizable: Toggle sessions on/off and adjust colors, transparency, and specific start/end times via the Inputs menu.

Release Notes
"Smart-Sync Technology: This indicator features a dual-timezone engine. While the morning session is locked to Europe/London to capture the UK open, the afternoon session is locked to America/New_York. This ensures the highlight automatically adjusts during the 'mismatch weeks' in March and October when US and UK daylight savings dates differ, keeping you perfectly synced with the 14:30 (or 13:30) Wall Street Open."Open-source script
