ICT Killzones - High/Low

255
This indicator highlights the key time-based trading sessions defined by the ICT (Inner Circle Trader) methodology — periods of the day when institutional order flow and liquidity are historically concentrated, making them prime windows for high-probability setups.

Sessions plotted:

Asian Killzone (e.g., 20:00–00:00 EST) — accumulation/range-building phase, often sets up liquidity for later sessions
London Killzone (e.g., 02:00–05:00 EST) — first major volatility expansion, frequently sweeps Asian session highs/lows
New York Killzone (e.g., 07:00–10:00 EST) — overlaps with London close, typically the highest-volume, highest-volatility window of the day
London Close Killzone (e.g., 10:00–12:00 EST) — optional reversal/continuation window as European desks exit positions
Features:

Shaded vertical session boxes drawn directly on the chart for each killzone
Customizable time ranges to match your broker's timezone/session offsets
Optional high/low markers for each session to track liquidity sweeps and raids
Toggle visibility per session and adjust colors/opacity independently
Session labels for quick visual reference
Use case: Combine with ICT concepts like liquidity sweeps, fair value gaps (FVG), and market structure shifts (MSS) to time entries within these windows rather than trading blindly throughout the day.
