ICT Kill Zones (Killzones): The Best Session Times to Trade

Kill zones are not patterns to recognise — they are windows on the clock. ICT setups work during them not because the pattern changes, but because institutional participants are actually present during these hours, creating the liquidity and displacement that makes the methodology reliable.

Key Takeaways

Kill zones are specific time windows — not price patterns — where institutional participation is highest and ICT setups are most reliable
Three primary kill zones: Asian Range (10 PM – 1 AM UTC), London Open (2 AM – 5 AM UTC), New York Open (7 AM – 10 AM UTC)
The Asian Range sets the session highs and lows that London and New York then target with sweeps and reversals
The Silver Bullet is a specific 1-hour entry window that sits inside either the London or New York kill zone
Kill zones give daily bias a time dimension — bias tells you direction, kill zone tells you when

What is an ICT Kill Zone?

A kill zone is a specific time window during the trading day when institutional participants are most active. These are not arbitrary times chosen by ICT — they correspond to the opening hours of the world’s major financial centres, when banks, hedge funds, and other large participants are actually at their desks executing orders.

Simple definition

A kill zone = a time window of heightened institutional activity, where the liquidity and displacement needed for clean ICT setups are most consistently available. Setup mechanics are the same outside kill zones — the reliability is not.

This is one of the most practical parts of the ICT framework for traders with day jobs or fixed schedules: rather than needing to watch charts all day, kill zone traders focus exclusively on these three windows. A setup that forms during a kill zone and aligns with daily bias is meaningfully more reliable than the identical setup forming during the quiet mid-session period.

The Three ICT Kill Zones — Times and Overview

There are three primary kill zones. The diagram below shows their positions across a 24-hour UTC trading day.

Figure 1 — The three ICT kill zones plotted on a 24-hour UTC timeline. Each hatched band marks a period of concentrated institutional activity.

Kill Zone	UTC Time	EST Time	Primary Character
Asian Range	10:00 PM – 1:00 AM	5:00 PM – 8:00 PM	Consolidation — builds the range that London and NY target
London Open	2:00 AM – 5:00 AM	9:00 PM – 12:00 AM	Manipulation — often sweeps the Asian range, then reverses
New York Open	7:00 AM – 10:00 AM	2:00 AM – 5:00 AM	Distribution — continues or extends the London directional move

Asian Range Kill Zone

The Asian Range — running from approximately 10:00 PM to 1:00 AM UTC (5:00 PM to 8:00 PM EST) — is typically the quietest of the three windows in terms of directional movement. Price tends to consolidate during this period, establishing a defined range high and a range low that serve as the liquidity targets for the sessions that follow.

In AMD terms, the Asian Range is predominantly the Accumulation phase — building the energy and setting the stage. The high and low of the Asian Range are the single most important reference levels for the London session, because London’s first move will very often sweep one of those levels before reversing in the direction of the day’s genuine bias.

London Open Kill Zone

The London Open — running from approximately 2:00 AM to 5:00 AM UTC (9:00 PM to midnight EST) — is the highest-volume foreign exchange session in the world, and the kill zone where the most dramatic price moves frequently originate. London participants are the primary drivers of EUR, GBP, and CHF pairs, bringing the largest block of institutional order flow into the day.

The characteristic pattern in the London Open kill zone is the Judas Swing: price initially moves against the day’s genuine directional bias, sweeping the Asian Range high or low and triggering the resting stop orders clustered there. After the sweep, price reverses sharply and begins the real move in the true direction of the daily bias. This is AMD’s Manipulation phase, compressed into the first 30–60 minutes of London’s session.

New York Open Kill Zone

The New York Open — running from approximately 7:00 AM to 10:00 AM UTC (2:00 AM to 5:00 AM EST) — overlaps briefly with the late London session and brings the largest equity and futures volumes of the day. For traders focused on US indices (NQ, ES, YM) or the major USD pairs, the New York Open is frequently the most important session.

In AMD terms, New York typically represents the Distribution phase continuation — extending or confirming the directional move that London established. In practice this means that when London’s reversal off the Judas Swing is strong, New York participants often push the same move further rather than reversing it.

The London–New York overlap window (roughly 7:00 AM to 8:30 AM UTC) can be particularly volatile and is worth special attention for traders who can be at their screens during this period.

Kill Zone Price Action — What Each Session Looks Like

Understanding the timing is only half the picture — the other half is recognising the characteristic price action each kill zone tends to produce.

Figure 2 — A typical session: Asian Range consolidates and sets the high/low references. London sweeps the Asian low (Judas Swing) and reverses. New York continues the London directional move with a second displacement.

This three-act structure maps directly onto the AMD cycle from Article 23: Asian = Accumulation, London Judas Swing = Manipulation, London reversal + New York continuation = Distribution. Recognising this structure before each session begins — and having your daily bias already determined — is the complete preparation needed to trade the kill zones effectively.

Silver Bullet — A Kill Zone Within a Kill Zone

The ICT Silver Bullet is a specific, tightly-defined entry model that operates within a precise sub-window of either the London or New York kill zone. Rather than trading the full 3-hour kill zone window, Silver Bullet traders focus on a 1-hour window that sits inside it, where setup quality is concentrated further.

The Silver Bullet windows are:

Kill Zones and Daily Bias

Kill zones are the timing layer; daily bias is the directional layer. Neither is complete without the other. Kill zone alone tells you when to be at your screen. Daily bias alone tells you which direction to trade. Together, they give you: the right direction, at the right time — which is the minimal viable trade thesis for any ICT model.

In practical terms: determine your daily bias before the London Open (using the process covered in our daily bias framework), then watch the London kill zone for a Judas Swing against your bias followed by a reversal in the bias direction. The kill zone provides the timing; the bias provides the filter. See our complete ICT Trading Strategy framework for how these layers combine with liquidity targeting and PD array entries.

Frequently Asked Questions

Kill Zone Exceptions: When the Pattern Does Not Apply

There are four conditions that reduce kill zone reliability significantly. First, major economic events (NFP, CPI, FOMC) that fall within a kill zone can distort the normal session dynamics. The data-driven spike disrupts the typical AMD sequence and creates atypically large FVGs that may not behave like normal kill zone setups. During major news events, wait for 5-10 minutes post-release before looking for kill zone entries.

Second, holiday sessions and low-volume trading days (the week between Christmas and New Year, US national holidays) produce weaker kill zone setups because institutional participation is reduced. The manipulation phase still occurs but the distribution delivery is less clean and the targets are less likely to be fully reached within the session.

Third, the first day of a new week (Monday) and the first day of a new month often behave differently in kill zones because institutional position re-balancing creates order flow patterns that differ from the typical session delivery. Monday kill zones require extra confirmation before entry. Fourth, the afternoon Silver Bullet window (2:00-3:00 PM New York) is the weakest of the three kill zone opportunities — lower volume and liquidity than the morning windows produces less reliable FVGs and weaker delivery. Treat afternoon setups with proportionally smaller size.

What are ICT kill zones?+

ICT kill zones are specific time windows during the trading day when institutional participants are most active, making ICT price action setups more reliable. The three primary kill zones correspond to the Asian Range (10 PM–1 AM UTC), London Open (2 AM–5 AM UTC), and New York Open (7 AM–10 AM UTC).

What are the ICT killzone times?+

Asian Range: 10 PM–1 AM UTC (5–8 PM EST). London Open: 2 AM–5 AM UTC (9 PM–midnight EST). New York Open: 7 AM–10 AM UTC (2–5 AM EST). Times shift slightly with daylight saving adjustments — always verify against your broker's server time.

Which kill zone is best for beginners?+

Most ICT educators recommend the New York Open for beginners in the US and the London Open for European traders, since these are the windows where traders are most naturally alert during their local waking hours. The Asian Range is the quietest session and typically produces the least directional movement — it is better understood as a reference-building session than a primary entry window.

Can I trade ICT outside kill zones?+

Yes, but with meaningfully lower reliability. The ICT methodology does not prohibit trading outside kill zones — all the same pattern rules apply. However, kill zone windows exist precisely because institutional participation (and therefore the liquidity and displacement that makes ICT setups work) is concentrated into these hours. Trading the same patterns during the quiet mid-session period will produce less consistent results.

What are the Silver Bullet times to trade?+

The ICT Silver Bullet uses three sub-windows within the broader kill zones: London Silver Bullet at 3:00–4:00 AM UTC, New York AM Silver Bullet at 8:00–9:00 AM UTC, and New York PM Silver Bullet at 2:00–3:00 PM UTC. See our complete Silver Bullet guide for the full entry model.
