ICT Kill Zones Explained — London Open, NY Open and More
ICT Kill Zones are specific time windows when institutional trading activity peaks and the highest probability setups tend to form. Trading outside of Kill Zones dramatically reduces the quality of your setups. Understanding when each session opens and what happens in each window is foundational to the ICT methodology.
What Are ICT Kill Zones?
Kill Zones are time windows identified by Michael Huddleston (ICT) during which banks and institutional traders are most active. During these windows, liquidity is hunted, manipulations occur, and the true directional move for the session typically begins. Trading during Kill Zones gives you the best alignment with smart money activity.
The Four ICT Kill Zones (All Times ET)
Asian Kill Zone — 8:00 PM to 12:00 AM ET
The quietest session. Price typically consolidates and builds a range. Asian session highs and lows become key reference points for the London and New York sessions. ICT traders use this session to mark key levels rather than actively trade.
London Open Kill Zone — 2:00 AM to 5:00 AM ET
One of the most powerful windows. The London session opens and institutional players in Europe begin moving markets. Price often hunts liquidity from the Asian session — taking out Asian lows before rallying or Asian highs before dropping. This manipulation move sets the direction for the rest of the session.
New York Open Kill Zone — 8:30 AM to 11:00 AM ET
The highest volume window of the day for US futures. Economic releases hit at 8:30 AM ET. The NY Open Kill Zone is where most of the day's range is built and where the London/NY overlap occurs (9:30 AM to 11:00 AM). For NQ traders this is the primary trading window.
New York Afternoon Kill Zone — 1:30 PM to 4:00 PM ET
A secondary opportunity window in the afternoon session. Less reliable than the morning but can produce clean setups, particularly when price has left unmitigated FVGs or order blocks from the morning session.
How to Use Kill Zones for Prop Firm Trading
Kill Zones solve one of the biggest problems prop traders face — overtrading. When you commit to only trading during Kill Zones, you naturally reduce your trade count and increase setup quality. Taking 2 trades per week during the NY Open Kill Zone is far more effective than taking 10 random trades throughout the day.
Kill Zones and Economic Releases
High impact news events like NFP, CPI, and FOMC decisions overlap with Kill Zones — particularly the NY Open. Always check the economic calendar before trading the morning Kill Zone. Many prop firm traders avoid being in positions around major releases entirely.
