Most ICT traders know kill zones exist. Far fewer understand why each one behaves differently, how to use them as a hard filter, or why technically correct setups keep failing at the wrong time. The result is traders who know the concept but apply it inconsistently — entering setups in dead zones, missing the real moves during peak sessions, and wondering why their technically correct analysis keeps producing losses.
This guide fixes that.
Why Kill Zones Exist — The Institutional Reality
Kill zones aren't arbitrary time windows someone invented. They're the periods when institutional order flow actually enters the market.
Banks, hedge funds, and market makers don't trade around the clock. They operate during business hours in their financial centers. London institutions dominate during European hours. New York institutions drive the US session. When these players activate, volume increases, spreads tighten, and price moves with directional intent rather than random noise.
The ICT methodology is built around this reality. Kill zones are the windows when the big players are most likely to be engineering liquidity — sweeping stops, taking out retail positions, and then delivering price toward their institutional targets.
Outside kill zones, price action becomes genuinely low-probability. A perfect-looking FVG at 2:00 PM fails not because the pattern was wrong, but because nobody with real capital committed to a direction. This is the most important reframe in all of ICT: the setup is secondary. The timing is primary.
The Four ICT Kill Zones
Asian Kill Zone — 8:00 PM to 12:00 AM EST
The Asian Kill Zone is unique. ICT classifies it as a kill zone, but it functions very differently from the three that follow. Rather than producing high-directional moves, the Asian session primarily builds the range that London and New York will then target.
During these hours, price consolidates — forming a recognizable high and low that represents resting liquidity. When London opens, it almost always sweeps one side of the Asian range before establishing the day's real direction. Those Asian highs and lows become your BSL (buy-side liquidity) and SSL (sell-side liquidity) reference points for the morning.
On JPY pairs (USD/JPY, GBP/JPY), genuine directional moves occur during Asian hours. A qualifying setup with clear HTF bias on these pairs during the 8 PM–12 AM window has validity. On EUR/USD, GBP/USD, and indices — mark the range, don't trade it.
London Open Kill Zone — 2:00 AM to 5:00 AM EST
London is where the day's directional bias most often gets established. The most powerful window within this kill zone is 2:00 AM to 4:00 AM EST — when the manipulation phase is sharpest and setups are cleanest. Setup quality tends to decline after the first two hours.
The classic London sequence: price sweeps one side of the Asian range, a large displacement candle follows, and a Fair Value Gap is left behind. The entire setup can happen within the first 30–45 minutes of the kill zone opening.
If price is drifting through the Asian range in both directions without committing, or there's no clear displacement after the first sweep attempt by 4:00 AM — the London session is not offering a quality setup today. Close the charts and wait for New York.
Primary pairs: EUR/USD and GBP/USD. GBP/USD specifically tends to have sharper liquidity sweeps at London open due to Bank of England proximity and Sterling liquidity dynamics.
New York Open Kill Zone — 8:30 AM to 11:00 AM EST
The New York open is the highest-probability kill zone in the ICT framework. The overlap with the closing London session creates the highest volume window of the trading day. More capital is transacting in this two-hour window than in any other period.
Within the broader New York open kill zone, the 10:00–11:00 AM window is specifically where the Silver Bullet strategy operates. After the initial NY volatility settles and the true direction is confirmed, this one-hour window frequently delivers the cleanest FVG or order block retracement setup of the entire day. If you only trade one window — this is the one.
Session invalidation criteria: If price opens flat and shows less than 50% of the average daily range by 9:30 AM, or if London already took the full day's range, or if there's no clear sweep and displacement by 10:00 AM — stop. The New York dead zone begins at 11:30 AM.
Primary instruments: GBP/USD, EUR/USD, NAS100, US30, XAU/USD. Indices specifically come alive at the NY open — NAS100 and US30 show some of the cleanest ICT setups in this window.
London Close Kill Zone — 10:00 AM to 12:00 PM EST
The London close is the final kill zone of the day. European institutions are closing positions before their business day ends — this profit-taking creates predictable, if lower-probability, directional flow.
The London Close is worth trading in three specific scenarios:
- The NY reversal setup: Morning trend was strongly bullish into a premium zone. By 10:00 AM, London institutions take profits. Price retraces and creates a bearish FVG — a continuation short if your daily bias is bearish.
- The failed London move completion: London started a move that never fully reached its target. At the close, NY institutions pick up where London left off and deliver price to the intended level.
- The Silver Bullet 10:00–11:00 AM window: This overlaps with both the NY open and London close — the highest-precision sub-window of the day.
If you already have a profitable trade running, the morning was directionless, or you've taken a loss in the morning session — skip the London close. It is not where you recover losses.

A Real Setup — London Open on GBP/USD
Here's exactly how a qualifying London open setup looks, with specific price levels:
It's Tuesday morning. The daily bias on GBP/USD is bearish — price is in a premium zone on the daily chart and the draw on liquidity is the previous week's low below.
During the Asian session, GBP/USD consolidates between 1.27420 (Asian high / BSL) and 1.27180 (Asian low / SSL). Both levels are marked.
At 2:14 AM EST, London opens and price begins pushing higher. By 2:22 AM it has traded through the Asian high at 1.27420 — sweeping the buy-side liquidity above. Retail breakout buyers are now long.
At 2:24 AM: a large bearish displacement candle drops from 1.27455 to 1.27340 in a single 5-minute candle — a 115-pip displacement. This creates a bearish FVG between 1.27410 (high of candle before displacement) and 1.27365 (low of candle after). The 50% level is 1.27388.
On the 5-minute chart, an MSS confirms — a short-term low is broken with displacement after the initial sweep.
Kill Zones and Daily Bias — The Inseparable Pair
Kill zones and daily bias cannot be used in isolation. The kill zone tells you when to trade. Daily bias tells you which direction to trade within that window.
Before any kill zone opens, you must know: the HTF direction, the draw on liquidity, and whether price is in premium or discount. With those established, you enter the kill zone with a directional filter — looking for one specific setup type aligned with the institutional delivery path.
A kill zone with no bias is still just time on a chart. The bias is what makes the kill zone actionable.
The Core Rule: Kill Zones as a Non-Negotiable Filter
Apply this without exception: if the setup didn't form during a kill zone, skip it.
This isn't a guideline. It's the filter that separates a system with edge from random price action analysis. An FVG that forms at 2:00 PM is not the same trade as an FVG that forms at 2:30 AM during London open. The pattern is identical. The probability is not.
Traders who struggle with ICT almost always share one characteristic: they trade outside kill zones. They find clean setups in dead zones, enter because the pattern is technically correct, get stopped out repeatedly, and conclude the methodology is flawed.
The methodology isn't flawed. The timing was wrong.
One qualifying kill zone setup per day, executed with full confluence, is all you need. The discipline to skip everything else is what makes the one good trade possible. Patience is not waiting for something to happen — it's knowing precisely what you're waiting for.
Common Kill Zone Mistakes
- Trading every kill zone every day. Not every session has a clean setup. Some days London is genuinely choppy with no clear manipulation. The discipline is recognizing when the kill zone isn't offering quality and walking away.
- Treating kill zone opens as entry signals. The kill zone opening is not a signal to enter. It's a signal to pay attention. You still need a sweep, an MSS, a qualifying FVG, and HTF alignment.
- Over-trading the New York lunch (11:30 AM–1:30 PM). Volume drops sharply, spreads widen, price chops. Many traders lose back their morning profits here. Once the NY open kill zone ends, stop trading unless you're managing an open position.
- Confusing kill zone timing across time zones. Kill zones are given in EST. Being off by even one hour means you're entering setups late when institutional flow has already committed. Use a time zone converter or the live kill zone timer.
- Watching too many pairs simultaneously. During London open, EUR/USD and GBP/USD. During NY open, add NAS100 and GBP/USD. Trying to watch six pairs across multiple kill zones leads to chasing setups and entering late.
Kill Zone Times and Daylight Saving Time
Kill zone times are always expressed in New York time (EST/EDT). The times never change — what changes is how they convert to your local timezone if you observe different daylight saving rules than the US.
If you always read the NY clock, the kill zone times stay identical year-round. The US shifts clocks on the second Sunday in March (spring forward) and first Sunday in November (fall back). During EDT (summer), NY is UTC-4. During EST (winter), NY is UTC-5.
| Kill Zone | NY Time (always) | UTC (Winter / EST) | UTC (Summer / EDT) | London (GMT+0/+1) |
|---|---|---|---|---|
| Asian Range | 8:00 PM – 12:00 AM | 01:00 – 05:00 UTC | 00:00 – 04:00 UTC | 1–5 AM / 12–4 AM |
| London Open | 2:00 AM – 5:00 AM | 07:00 – 10:00 UTC | 06:00 – 09:00 UTC | 7–10 AM / 8–11 AM |
| New York Open | 8:30 AM – 11:00 AM | 13:30 – 16:00 UTC | 12:30 – 15:00 UTC | 1:30–4 PM / 2:30–5 PM |
| London Close | 10:00 AM – 12:00 PM | 15:00 – 17:00 UTC | 14:00 – 16:00 UTC | 3–5 PM / 4–6 PM |
Who needs to adjust: If you trade from a timezone that does not observe US daylight saving — such as most of Asia, parts of Europe outside the UK, or countries on fixed UTC offsets — your local equivalent of NY time shifts by one hour in March and again in November. The NY times themselves never move. Set your trading platform to New York time and never think about DST again.
