Weekly & Daily Opening Gaps — NWOG & NDOG Indicator
Professional-grade opening gap visualization for institutional traders and serious retail participants
OVERVIEW
Weekly & Daily Opening Gaps (NWOG & NDOG) is a precision indicator designed for traders who use opening gap analysis as part of their methodology — including ICT, Smart Money Concepts, and institutional flow strategies.
The indicator automatically detects, draws, and manages New Week Opening Gaps (NWOG) and New Day Opening Gaps (NDOG) directly on your chart. Each gap is rendered as a clearly visible price zone, with full customization of colours, transparency, labels, and extension behaviour.
Built with a modular, performance-optimized architecture, the indicator handles large historical datasets without slowing down your platform — making it equally suitable for backtesting and live trading.

HOW IT WORKS
NWOG Strategy — Detects the first Sunday bar each week. The gap zone is drawn between the previous Friday close and the Sunday open, spanning from session open to Friday 21:00 UTC.
NDOG Strategy — Detects the first bar at each daily session open (Mon–Thu: 21:00 UTC, Sun: 22:00 UTC). The gap zone spans between the previous session close and the current session open.
Event Horizon — Calculates the midpoint between two consecutive NWOGs that do not overlap. This level represents the gravitational centre between two liquidity pools and is drawn as a horizontal trend line.
