Formula: Local Time = UTC Time + UTC Offset (+1 if local DST)
Worked example — London KZ: 2-5 AM | NY KZ: 7-10 AM | Asia: 7 PM-12 AM
Formula
Local Time = UTC Time + UTC Offset (+1 if local DST)
All ICT killzones are defined in UTC/New York time. The London killzone runs 7:00-10:00 UTC (2:00-5:00 AM NY). Convert to local time by adding your UTC offset. Account for both local DST and UK DST, which change on different dates, creating transition periods where the effective offset shifts.
Worked Examples
Example 1: New York EST Trader - Winter Schedule
Problem:A trader in New York (UTC-5, no DST) needs all ICT killzone times in their local time. UK is also not in DST (GMT).
Solution:London Open KZ: 7:00-10:00 UTC = 2:00-5:00 AM EST New York KZ: 12:00-15:00 UTC = 7:00-10:00 AM EST Asian Session: 0:00-5:00 UTC = 7:00 PM-12:00 AM EST (prev day) London Close: 14:00-16:00 UTC = 9:00-11:00 AM EST Silver Bullet 1 (London): 10:00-11:00 UTC = 5:00-6:00 AM EST Silver Bullet 2 (NY AM): 14:00-15:00 UTC = 9:00-10:00 AM EST Silver Bullet 3 (NY PM): 19:00-20:00 UTC = 2:00-3:00 PM EST
Result:London KZ: 2-5 AM | NY KZ: 7-10 AM | Asia: 7 PM-12 AM
Example 2: Dubai Trader - GST (UTC+4)
Problem:A trader in Dubai (UTC+4, no DST) needs London killzone and Silver Bullet times.
Solution:London Open KZ: 7:00-10:00 UTC + 4 = 11:00 AM-2:00 PM GST New York KZ: 12:00-15:00 UTC + 4 = 4:00-7:00 PM GST Asian Session: 0:00-5:00 UTC + 4 = 4:00-9:00 AM GST Silver Bullet 1: 10:00-11:00 UTC + 4 = 2:00-3:00 PM GST Silver Bullet 2: 14:00-15:00 UTC + 4 = 6:00-7:00 PM GST Silver Bullet 3: 19:00-20:00 UTC + 4 = 11:00 PM-12:00 AM GST
Result:London KZ: 11 AM-2 PM | NY KZ: 4-7 PM | Convenient daytime trading
Frequently Asked Questions
What is the London Open Killzone in ICT trading?
The London Open Killzone (LOKZ) is a specific time window identified by ICT (Inner Circle Trader) during which the highest probability trading setups occur as the London session begins. The standard killzone runs from 2:00 AM to 5:00 AM New York time (7:00 to 10:00 UTC). During this window, institutional traders in London begin placing their orders, creating significant volatility and directional moves. ICT teaches that this is when the daily range expansion typically begins, making it one of the most important trading windows of the day. The killzone concept helps traders focus their analysis and execution on the times when smart money is most active and price moves are most reliable.
Why is the London session considered the most important forex session?
The London session handles approximately 35 to 40 percent of all daily forex volume, making it the largest single trading session in the world. This dominance occurs because London sits at the intersection of Asian and American trading hours, creating natural overlap periods with both sessions. Major European banks, hedge funds, and institutional traders execute their daily orders during London hours. The session produces the widest daily price ranges for most currency pairs, particularly European crosses. ICT emphasizes that roughly 70% of the daily high or low is formed during London hours. The concentration of institutional activity means that price moves during the London session are more likely to represent genuine institutional direction rather than noise.
How do Daylight Saving Time changes affect the killzone?
Daylight Saving Time (DST) changes significantly impact killzone timing because the US and UK switch at different dates. The US springs forward on the second Sunday in March and falls back on the first Sunday in November. The UK changes on the last Sunday in March and last Sunday in October. This creates a two-to-three week gap where the time difference between London and New York changes by one hour. During these transition periods, the London killzone effectively shifts by one hour relative to New York time. ICT traders must account for these shifts by recalculating their local killzone times whenever DST changes occur. Failing to adjust can cause traders to enter positions outside the optimal window, reducing the probability of their setups.
What typically happens during the London killzone?
During the London killzone, several predictable market behaviors typically occur in sequence. First, there is often a false move or Judas Swing that sweeps the Asian session high or low, trapping retail traders on the wrong side. Then, the true daily directional move begins with strong displacement candles showing institutional commitment. This displacement usually includes the formation of fair value gaps and order blocks that serve as potential entry points on pullbacks. Volume increases dramatically compared to the Asian session, and spreads on major pairs narrow as liquidity floods the market. The first 30 minutes of the killzone often set up the direction, while the remaining time sees the initial expansion. Most of the significant daily levels are established during this three-hour window.
What are Silver Bullet windows and how do they relate to killzones?
Silver Bullet windows are specific one-hour time intervals identified by ICT where high-probability trading setups occur with remarkable consistency. The three main Silver Bullet windows are: London AM (10:00-11:00 UTC or 5:00-6:00 AM NY), New York AM (14:00-15:00 UTC or 9:00-10:00 AM NY around the equities open), and New York PM (19:00-20:00 UTC or 2:00-3:00 PM NY). These windows fall within or adjacent to the broader killzones and represent concentrated bursts of institutional activity. During Silver Bullet windows, traders look for displacement followed by a return to a fair value gap. The concept narrows the killzone further, providing even more focused timing for trade entries.
How does the London-New York overlap killzone differ from the London open?
The London-New York overlap period (12:00-15:00 UTC or 7:00-10:00 AM NY) is distinct from the London Open killzone in both character and purpose. During the overlap, both major financial centers are actively trading, creating the highest liquidity of the day. While the London Open typically establishes the daily direction, the overlap period either continues the London session move or reverses it. ICT teaches that the overlap is where the daily high or low is often formed on reversal days. The New York session can confirm the London direction by breaking further in the same direction, or it can create a reversal by sweeping the London session extreme and reversing. Traders who missed the London Open often find the second-best entries during this overlap window.
What are ICT macro times and how do they fit within killzones?
ICT macro times are very specific short windows (usually 20 to 30 minutes) within the broader killzones where price tends to make significant moves. Key macro times include 9:30-10:00 UTC (London session expansion), 10:50-11:10 UTC (London session continuation or reversal), and 14:30-15:00 UTC (New York equities opening reaction). These micro-windows align with specific institutional activities such as fixing rates, equity market opens, and options expiration times. ICT traders who understand macro times can time their entries with even greater precision than using killzones alone. The macro times essentially pinpoint the exact moments within a killzone when institutional algorithms are most likely to execute large orders, creating the displacement and liquidity events that form trading opportunities.
Should all forex pairs be traded during the London killzone?
While the London killzone is the most versatile trading window, not all currency pairs perform equally well during this time. European pairs like EURUSD, GBPUSD, EURGBP, and EURCHF are ideal because European institutional flows directly impact these currencies. The US Dollar index and its major pairs also move well because London traders actively position ahead of US data releases. However, pairs like AUDUSD and NZDUSD may show better setups during the Asian-London overlap or during their respective domestic sessions. USDJPY can work during London but often produces its best moves during the New York session. ICT recommends focusing on no more than two to three pairs during any killzone to maintain analysis quality and avoid overtrading across too many instruments.
How do you adjust killzone times for different time zones around the world?
To adjust killzone times for your local time zone, add your UTC offset to the standard UTC times. The London killzone runs 7:00-10:00 UTC, so a trader in Dubai (UTC+4) would trade from 11:00 AM to 2:00 PM local time. A trader in Sydney (UTC+10 or UTC+11 during DST) would have the London killzone at 5:00-8:00 PM or 6:00-9:00 PM. This means some traders in Pacific time zones can trade the London session during their evening hours. ICT emphasizes that understanding your local killzone times is essential because trading outside these windows dramatically reduces setup quality. Many traders set alarms for their local killzone start times and build their daily routines around these specific hours.
What confirmation signals should you look for within the London killzone?
Within the London killzone, ICT traders look for several key confirmation signals before entering trades. First, a sweep of the Asian session high or low provides the initial liquidity event. Second, displacement candles (large-bodied candles with minimal wicks) confirm institutional commitment to a direction. Third, the formation of a fair value gap (FVG) within the displacement provides a potential entry zone on the pullback. Fourth, an order block (the last opposing candle before the displacement move) serves as an additional entry point. Fifth, a market structure shift (break of a recent swing high or low) confirms the directional change. The strongest setups combine multiple confirmations: a liquidity sweep followed by displacement through an order block, creating an FVG, with a break of market structure, all occurring within the killzone window.
