ICT Killzone Times: Asian, London & New York Sessions

Framework note: ICT terms are interpretations of price action, not proof of institutional motives or a market algorithm’s intent. No setup is guaranteed. Test clearly defined rules, account for costs and slippage, and use risk limits before risking capital. Read our editorial policy.

ICT Killzones are session windows that traders use to focus chart review. Liquidity and volatility can vary across sessions, but these windows do not guarantee cleaner price action or higher win rates. Test a time filter on your instrument, timeframe and rules.

Why Time Matters More Than Most Traders Think

Market activity and volatility vary by instrument, session and news conditions. Session overlaps can coincide with higher activity, but a chart does not show that the largest institutional orders always enter during a particular window.

A setup's outcome may differ by session, but assigning it a different probability requires a defined instrument, rule set and sample. Do not infer that the same chart pattern is more reliable just because it appears during a named window.

Asian Session (7 PM – 12 AM New York time) — Range Reference

In some ICT routines, the Asian-session high and low are marked as a range for later comparison. The range may be narrow or wide; neither the session label nor the range proves that participants are accumulating positions or predicts a later sweep. If you use this range, define the start and end in New York local time and record the outcome.

Some ICT traders mark the Asian high and low as candidate references for the London session. Price can break one side, both sides, or neither; a Judas Swing interpretation is a hypothesis, not proof of manipulation or a forecast of the day's direction. Define the trigger and invalidation before testing the setup.

London Killzone (2 AM – 5 AM New York time) — Session Context

ICT materials commonly study the London window for potential range breaks and reversals. Activity, spreads and volatility vary by instrument and date; a move across a marked range does not establish why it occurred or guarantee a reversal. Define the observable conditions and compare outcomes with other time windows.

One scenario some ICT traders study is a move beyond the Asian high or low followed by a return inside the range. The move may reverse, continue, or remain inside the range; candles alone do not prove that breakout traders were deliberately trapped. Log both matching and non-matching outcomes using the same definition.

New York AM Killzone (7 AM – 11 AM New York time) — Session Context

Some ICT strategies examine the New York morning and the commonly cited 10–11 AM Silver Bullet window. This does not establish that it is the most important window for every instrument, that institutional orders are highest then, or that a setup has an edge. Define the model and compare results across windows.

The London–New York overlap is one period traders may choose to study. It does not by itself show that liquidity is deepest for every instrument or that London has established the day's direction. Test any overlap filter against a comparison window using identical entry, exit and risk rules.

Named ICT Macro Times — Context, Not a Schedule

Some ICT sources discuss specific macro timestamps, but labels and definitions can differ. The times below are New York local time; account for daylight-saving changes. Treat them as reference points to test, not evidence of a scheduled algorithmic event or guaranteed price behavior.

• •2:33 AM New York time — an example London-session reference cited in some ICT materials
• •4:03 AM New York time — another London-session reference cited in some ICT materials
• •8:50 AM New York time — an example pre-market reference cited in some ICT materials
• •9:10 AM New York time — a New York-morning reference; not the commonly cited 10–11 AM Silver Bullet interval
• •10:00 AM New York time — a mid-morning reference; the regular NYSE core session opens at 9:30 AM ET
• •10:50 AM New York time — a point within the commonly cited 10–11 AM Silver Bullet interval
• •11:10 AM New York time — a later-morning reference; test rather than assume lunch-hour effects
• •1:10 PM New York time — an afternoon reference; define and test any claimed relationship to London close

Building Your Trading Day Around Killzones

A routine may use higher-timeframe context, mark the Asian-session range, and then observe one or more predefined London or New York windows. Trade only when the written setup trigger, invalidation and risk rules are met; no session requires a sweep or reversal. If using a cutoff time, define it in New York local time and test it instead of treating it as a highest-quality window.

Worked hypothetical example: evaluate a session filter

A trader studies a 30-minute opening-range strategy both inside a predefined New York morning window and outside it. Each signal is logged using the same entry, stop and target rules; only the time filter differs. The trader uses New York local time and documents daylight-saving transitions to avoid accidentally shifting the sample by an hour.

Failure case and what to test

A setup can fail inside a commonly cited killzone, while a similar setup can work outside it. Session effects may differ across instruments, weekdays, volatility regimes and news conditions. Comparing many time windows after seeing results can overfit the sample.

Test checklist

• •Define time windows in a named timezone and handle daylight-saving changes.
• •Keep signal and risk rules identical between filtered and unfiltered samples.
• •Record skipped, losing and winning signals plus major scheduled news.
• •Compare out-of-sample expectancy, drawdown, sample size and costs.
