ICT Killzones explained: why London and New York sessions matter to traders

What are ICT Killzones?

ICT Killzones are specific periods during the London and New York trading sessions when market activity tends to increase sharply.

The London and New York Killzone receive the most attention, although some traders also monitor the Asian session and the London Close. In many cases, the Asian session establishes a relatively narrow trading range that later becomes the focus of London trading.

Instead of searching for setups throughout the day, Killzone allow traders to concentrate on the hours when price is most likely to leave consolidation and develop a meaningful move.

Why liquidity sweeps often happen during Killzone

Before the market makes a significant move, liquidity often builds around obvious highs and lows.

These levels attract breakout traders while also containing clusters of stop-loss orders from traders already in positions. Once institutional participation increases, price frequently moves through one of these areas before revealing its next direction.

For many SMC traders, the sweep itself is only the first step. They wait for confirmation, such as a market structure shift or displacement, before looking for an entry.

London Killzone trading model

For many ICT traders, the trading day truly begins when London opens. The London Killzone generally runs from 2:00 AM to 5:00 AM New York time, although the exact hours can vary slightly because of daylight saving changes.

After the relatively quiet Asian session, London often brings a noticeable increase in liquidity. The highs and lows formed overnight frequently become targets as institutional traders begin executing larger orders.

It is common to see price move beyond the Asian range before establishing the direction that dominates the rest of the session.

How to trade the London Killzone

Many traders begin the London session by looking at what happened overnight rather than focusing on the first candle after London opens.

The Asian session often forms a relatively tight trading range, creating obvious highs and lows where liquidity begins to build. When London opens, prices frequently move beyond one side of that range before deciding on its real direction.

Instead of chasing that initial breakout, wait to see how the market reacts. If price sweeps the Asian low and quickly moves back above it, buyers may be stepping in. If it sweeps the Asian high before reversing lower, sellers may be taking control.

Once the liquidity sweep is complete, look for confirmation. A break of structure or change of character shows that momentum has shifted. From there, wait for price to retrace into a fair value gap or order block rather than entering after the impulsive move.

What is the New York Killzone?

The New York Killzone begins as the US trading session opens while London is still active.

This overlap creates one of the busiest periods of the trading day, combining liquidity from the world's two largest financial centres. The session typically runs from 7:00 AM to 10:00 AM New York time, with slight adjustments during daylight saving periods.

Many important US economic reports, including inflation, employment, GDP and Federal Reserve announcements, are also released during this window, making it one of the most closely watched sessions for forex, indices and gold traders.

Why is the New York Killzone important?

The New York session often builds on the liquidity created earlier in London. Sometimes it extends the existing trend. At other times, major US economic data completely changes market direction.

Markets such as EUR/USD, Gold, Nasdaq and the S&P 500 often experience their highest trading activity during this period because they are influenced by both European and American order flow.

New York Killzone trading model

A common New York Killzone setup begins with price approaching an obvious high or low created earlier in the session. As New York opens, increased volatility often pushes price beyond that level, triggering stop-losses and breakout orders.

Rather than following the first move, many SMC traders wait to see whether the market rejects the breakout. If price quickly changes character and breaks market structure, it suggests that buyers or sellers have taken control.

The final step is waiting for price to be retraced into a fair value gap or order block before looking for an entry. This approach allows traders to enter after confirmation instead of reacting to the initial volatility.

How to trade the New York Killzone

The New York Killzone follows the same principles but often reacts to liquidity created during the London session. Before New York opens, identify the important highs and lows formed earlier in the day. These levels often become targets once U.S. traders enter the market and volatility increases.

If price sweeps one of those levels during the opening minutes, avoid assuming the breakout will continue. Wait to see whether the market accepts the move or quickly rejects it.

A rejection followed by a clear market structure shift can provide the confirmation many SMC traders look for. Instead of entering immediately, allow price to be retraced into a fair value gap or order block before considering a trade.

This is especially important on days when major U.S. economic data is released. News can create sharp moves in both directions before the market establishes a clearer trend. Waiting for confirmation helps reduce the risk of getting caught in the initial volatility.

London Kill Zone vs New York Killzone

The London Killzone frequently establishes the day's initial direction. It often attacks the highs or lows created during the Asian session before beginning a sustained move.

The New York Killzone usually reacts to liquidity created during the European session. Depending on market conditions, it may continue London's trend or completely reverse it, especially after major U.S. economic data.

Common mistakes when trading Killzones

One of the biggest mistakes is assuming that every London or New York open will produce a trade. Killzone increase the probability of meaningful price action, but they do not guarantee it. Some sessions remain quiet, while others produce false breakouts before establishing direction.

Another common mistake is entering as soon as price becomes volatile. A strong candle after the session opens is not confirmation by itself. Many false moves begin with aggressive momentum before quickly reversing.

Ignoring the higher-timeframe trend is another frequent error. A lower-timeframe setup that goes against the broader market direction often has a lower probability of succeeding.
