ICT Kill Zones: Session Timing Guide for MT4 and MT5

Most traders hunt for better signals. Also, traders who follow Inner Circle Trader concepts hunt for a better clock. ICT kill zones are the four time windows where institutional order flow concentrates: the Asian range, the London open, the New York open, and the London close. The premise is blunt. When you trade matters as much as what you trade. Indeed, the same setup that fails at a dead hour often works cleanly inside a kill zone, because the move it needs actual participation to complete. This guide gives you the four windows with honest times, explains why they exist, shows how the Asian range maps the whole day, pairs the windows with the Judas swing and silver bullet models, and lists the session tools from this library that draw everything automatically.

The four ICT kill zones and their times

Kill zones are anchored to New York local time, not to UTC and not to your broker’s clock. Still, that anchor matters, and we will return to it. The canonical windows look like this.

Asian range: 8:00 pm to 12:00 am New York time (roughly 01:00–05:00 UTC in winter). Thus, this is not a trading window for most ICT traders. It is the accumulation phase that builds the high and low the next sessions will run.

London kill zone: 2:00 am to 5:00 am New York time (roughly 07:00–10:00 UTC in winter). Hence, the most active window for EURUSD and GBPUSD. The daily high or low of many trading days forms here.

New York kill zone: 7:00 am to 10:00 am New York time (roughly 12:00–15:00 UTC in winter). Next, it wraps the 8:30 am news releases and the equities open, and it overlaps late London liquidity.

London close kill zone: 10:00 am to 12:00 pm New York time (roughly 15:00–17:00 UTC in winter). Then, a reversal-prone window as European desks square positions.

One honest caveat on the UTC figures: they shift by an hour when clocks change, and the US and UK switch on different dates. For a few weeks each March and each autumn, the usual offsets break. Anchor to New York time and the windows stay put.

Why kill zones exist

Kill zones are not magic hours. Yet, they map directly onto where trading volume actually sits during the day. Interbank desks, funds, and execution algorithms cluster their activity around session opens, scheduled news, and session closes. Truly, the London open releases orders built up overnight. The New York open adds US data releases and the stock market open on top of a London session that is still running. Plainly, that London–New York overlap is the deepest pool of liquidity in the entire 24-hour cycle.

Between these bursts, volume thins out. Also, spreads widen relative to the movement available, ranges compress, and breakouts starve. A signal that fires at 6:00 pm New York time is asking the market for follow-through at the exact hour the fewest participants are present. Indeed, kill zones simply concentrate your trading where the fuel is. Timing filters like this cost nothing and remove a whole class of losing trades: the ones taken when nobody was at the desk to move price.

Using the Asian range as the day’s map

The Asian session rarely trends on major pairs. Thus, it builds a box: a high and a low that hold resting liquidity in the form of stops from range traders and breakout orders from everyone else. ICT treats that box as the day’s reference map. Hence, mark the Asian high and low before London opens, then watch what the London kill zone does with them.

Three outcomes cover most days. Next, price sweeps one side of the range and reverses, which is the classic manipulation-then-distribution sequence. Price breaks one side cleanly and trends, which usually means news or a strong higher-timeframe draw. Then, or price stays inside the box, which tells you to stand down until New York. The point is not prediction. Yet, the point is that the Asian range gives every London move a context: either it is running the overnight liquidity or it is respecting it. Without the box marked, you are reading the open blind.

Combining kill zones with setups

A kill zone is a filter, not an entry. Truly, the window tells you when to pay attention; a setup model tells you what to do. The two best-known pairings both live inside specific windows.

The Judas swing belongs to the London open. Plainly, the model: early in the London kill zone, price makes a false push in one direction, typically through the Asian high or low, takes out the stops resting there, then reverses and runs the opposite way for the rest of the session. Traders who chase the first move provide the liquidity for the real one. Also, the practical playbook is to let the first push complete, wait for a structure shift back through the range, and target the other side of the Asian box.

The silver bullet narrows timing further, to three one-hour windows: 3:00–4:00 am, 10:00–11:00 am, and 2:00–3:00 pm New York time. Indeed, inside each window the model looks for one specific pattern, a fair value gap left by a displacement move, and trades its retest toward the nearest liquidity pool. These models lean on concepts covered across the whole smart-money toolkit; the ICT indicators guide walks through fair value gaps, order blocks, and liquidity tools in one place.

Check your broker’s server time first

Here is the mistake that ruins most kill zone charts: assuming your platform clock matches New York. It almost never does. Most MT4 and MT5 brokers run server time at GMT+2 in winter and GMT+3 in summer, so that daily candles close with the 5:00 pm New York session end. Still, some brokers sit at GMT+0 or elsewhere entirely. If you type the textbook hours into a session tool without converting, every zone lands in the wrong place and every conclusion you draw from the boxes is wrong.

The fix takes one minute. Thus, compare your platform’s market watch clock against New York time, note the offset, and shift each window by that amount. Every tool in the next section exposes its start and end hours as inputs for exactly this reason. Hence, set them once per broker, and re-check them each March and November when daylight saving moves the offset.

Session tools that draw the zones for you

Four tools from this library handle the drawing so you never mark sessions by hand. Next, all four ship as compiled MT4 and MT5 files, and all four take their session hours as inputs, so the server-time correction above is a one-time setting.

Tool	What it draws	Best timeframes	Alerts
ICT Kill Zone	Single configurable kill zone box with open and close marker lines, 500-bar history	M5–M30	Popup + push
Kill Zones	All four windows (Asia, London, New York, PM) as color-coded boxes, 30 days of history	M5–H1	Popup + push
ICT Killzones and Pivots	Four kill zone boxes plus daily pivot, support, and resistance levels	M15–H1	Popup
Session Box	Asia, London, and New York session boxes with per-session toggles and signal arrows	M15–H1	Popup + push

ICT Kill Zone

The minimalist of the group. Then, it draws one kill zone, London by default at server hours 2 to 5, as a shaded box with a colored line at the window open and another at the close, across a 500-bar lookback. Change the two hour inputs and it becomes a New York or London close tool instead. Yet, verdict: the cleanest chart if you trade a single window and want nothing else on screen. Limitation: one zone per chart means running several instances if you trade both London and New York, and each instance needs its own hour settings.

Kill Zones

The full-map tool. Truly, it draws all four windows, Asian, London, New York, and the afternoon close, as separate color-coded boxes with 30 days of history, so you can scroll back and study how each window behaved across a full month. Every window has its own start hour, end hour, and color input. Plainly, verdict: the best default for anyone learning the kill zone framework, because seeing all four windows at once teaches the daily rhythm faster than any article. Limitation: four boxes plus candles is a busy chart, and on M5 the shading can crowd out price action until you mute the colors.

ICT Killzones and Pivots

This one merges two frameworks. Also, it draws the four kill zone boxes and overlays classic daily pivot levels: the central pivot plus support and resistance lines, each with its own color. The combination answers a practical question: when price enters a kill zone, which nearby level is it likely reaching for? Indeed, a London sweep that lands exactly on the daily pivot is a more complete story than a sweep into empty space. Verdict: the pick for traders who already use pivots as targets and want time and level context on one chart. Still, limitation: alerts are popup-only in the current build, and the extra lines make it the busiest chart of the four.

Session Box

The generalist. Thus, it boxes the three major sessions rather than the narrower kill zone windows, with a show/hide toggle per session, and it adds signal arrows at a configurable pip offset from the candles. Session-level boxes suit swing traders who care whether a move happened in London or New York but do not trade the opens tick by tick. Hence, verdict: the right tool when you want session context on H1 charts without the tighter kill zone framing. Limitation: because the boxes span whole sessions, they are too wide to time entries from; pair it with one of the kill zone tools above for execution.

How to choose. Start with Kill Zones to learn the daily rhythm. Next, move to ICT Kill Zone once you settle on one window and want a minimal chart. Add ICT Killzones and Pivots if pivots are already part of your target selection. Then, keep Session Box for higher-timeframe context.

Testing and installation

Every tool above compiles clean in MetaEditor for both platforms and then runs on a live EURUSD chart through fresh bars before release. For session tools the critical check is anchoring: a box drawn for Monday’s London window must stay fixed to those exact candles on every later tick and after every platform restart. The full checklist is in the Editorial and Testing Policy. Yet, installation takes about five minutes per tool; the step-by-step MT4/MT5 installation guide covers both platforms with screenshots, including where the compiled .ex4 and .ex5 files go.

FAQ

What times are the ICT kill zones exactly?

In New York time: Asian range 8:00 pm–12:00 am, London 2:00–5:00 am, New York 7:00–10:00 am, London close 10:00 am–12:00 pm. Truly, UTC equivalents shift with daylight saving, so convert from New York time.

Do kill zones work for gold and indices?

Yes for gold, which trades most actively through the London–New York overlap. Plainly, indices follow their own exchange hours: the New York window applies to US indices, London less so. The Asian range logic suits any 24-hour instrument.

Why do my zones look shifted compared to the textbook times?

Your broker’s server time is not New York time. Also, most MT4/MT5 servers run GMT+2 or GMT+3, so textbook hours land two to three hours off. Adjust the hour inputs in each tool; re-check after each daylight saving change.

Which kill zone suits beginners best?

The London kill zone. Indeed, it has one clear reference, the Asian range, a repeatable pattern in the Judas swing, and it finishes early in the day. The New York window adds news volatility, which punishes hesitation more.

Does trading only inside kill zones improve outcomes?

Timing filters remove trades taken in thin markets, which helps. Still, but a window is not a signal; your setup rules and risk sizing decide the outcome. Results are not guaranteed; past performance is not indicative of future results.
