What it means
Kill zones are time windows when price tends to move most, used by ICT-style traders to decide when to look for setups. Common definitions in New York time: Asian range 20:00–00:00, London 02:00–05:00, New York 07:00–10:00, London close 10:00–12:00.
They are conventions, not exchange rules. Different educators use slightly different hours.
Why traders use it
Volatility is not spread evenly through the day. Session opens bring new participants and scheduled data, so ranges tend to expand. Limiting analysis to these windows avoids trading slow, directionless hours.
Chart examples
Quiet Asia, active kill zones
How to identify it objectively
- 1Pick one definition and write it down, including the time zone.
- 2Convert to your local time for each date; London and New York change clocks on different days.
- 3Mark each window on the chart (shaded boxes help).
- 4Only consider setups that form inside an enabled window.
Bullish use
- 1Asia builds a range.
- 2In the London kill zone price sweeps the Asia low and reverses up.
- 3The bullish setup forms inside the window.
Bearish use
- 1Asia builds a range.
- 2In the New York kill zone price sweeps a high and reverses down.
- 3The bearish setup forms inside the window.
What confirms it
- The move begins inside the window.
- Range expansion compared with Asia.
What invalidates it
- The setup forms outside the windows.
- Times copied without adjusting for daylight saving.
How a hypothetical setup is built
Entry
Inside the kill zone, after a sweep and a confirmation close.
Stop
Beyond the sweep extreme.
Target
The opposite liquidity of the session range.

Historical testing
Not tested on The Tradeskill. You can test the time filter by comparing the same entry rule inside and outside the windows. The session clock in the Session Liquidity Playbook converts the times for any date.
Limitations: when it fails
- Window boundaries are arbitrary.
- News releases can move markets outside the windows.
- Holidays and thin sessions behave differently.
- For 24-hour crypto markets the relevance may differ from forex and gold.
