ICT kill zones are specific intraday time windows when institutional order flow is most active, so sweeps, displacement, and clean setups cluster inside them rather than randomly across the day. Instead of watching charts 24 hours, you focus on a few high-probability hours anchored to the London and New York sessions. The idea, drawn from Inner Circle Trader's work, is that large players transact when liquidity is deepest, and those windows repeat on a predictable schedule.
Key points
- A kill zone is a time filter, not a setup. It tells you when to look, not what to trade.
- The main windows are Asian, London Open, New York AM, and London Close (with a NY PM window some traders add).
- They work because session opens inject liquidity and create the stop pools that get run.
- All times below are US Eastern (EST/EDT); the market shifts one clock hour with daylight saving.
- A sweep inside a kill zone carries more weight than the same pattern at 3pm on a dead tape.
How to identify each kill zone window
Anchor them to Eastern time and let the session opens do the work. These are the windows ICT traders watch:
| Kill zone | Window (EST) | Typical behavior |
|---|---|---|
| Asian range | ~8pm–12am | Low volatility; builds the range that gets swept later |
| London Open | ~2am–5am | First real displacement; often runs Asian highs/lows |
| New York AM | ~7am–10am | Highest-probability window; judas swing then reversal |
| London Close | ~10am–12pm | Profit-taking, retracements, reversal of the AM move |
| New York PM | ~1:30pm–4pm | Secondary continuation or afternoon reversal |
The New York AM window is where most ICT models live. The Silver Bullet, a narrower 10am–11am EST setup, sits inside it. Note that the AM kill zone brackets the 8:30am EST economic releases, which is exactly why displacement is common there.
Why these windows produce sweeps and displacement
Session opens create liquidity, and liquidity is what algorithms hunt. When London or New York comes online, resting orders flood in: breakout stops above the Asian high, protective stops below overnight lows, pending orders at obvious levels. That concentration gives price a reason to reach for a pool before delivering the real move.
The classic sequence is the judas swing. Price pushes one direction early in the window, sweeps an obvious high or low, traps breakout traders, then reverses with displacement in the opposite direction. That false push is not noise; it's the mechanism that fills institutional size against retail stops. A single wide-range candle closing through structure after the sweep is your displacement confirmation.
Outside a kill zone, a sweep is a data point. Inside one, it's a signal. The clock is the confluence most traders leave out.
Kill zone versus session versus Silver Bullet
These get conflated constantly. A session (like the full London session) can run many hours. A kill zone is the concentrated sub-window inside or around that session where ICT expects the day's move to originate. The Silver Bullet is a specific one-hour tactic (10–11am EST is the most cited) with defined FVG entry rules. All three overlap; they aren't synonyms.
When it matters in practice
Kill zones matter most when you pair time with price. A discount-array setup that also triggers at 8am EST is far stronger than the same array at noon. Use the window to filter, not to force: no clean sweep and displacement means no trade, even inside the box.
Two practical habits sharpen this. First, timestamp every trade and review whether your winners cluster in specific windows; most traders find they do. Second, respect the daylight-saving shift and the news calendar, since a CPI print landing inside the NY AM window can turn an ordinary sweep into a violent one. The window tells you when institutional intent is likely; your model still has to confirm it.
