Formula: Status = Active if (Current UTC Hour >= Start UTC) AND (Current UTC Hour < End UTC) | Countdown = Start UTC − Current UTC
Worked example — Best windows: London Open (12-3PM) & NY Open (5-8PM PKT)
Formula
Status = Active if (Current UTC Hour >= Start UTC) AND (Current UTC Hour < End UTC) | Countdown = Start UTC − Current UTC
Each killzone has a fixed UTC start and end time. The timer checks the current UTC time against each killzone's window to determine if it is active. For upcoming killzones, the countdown calculates the time difference between now and the next killzone start. All times are converted to your local timezone using your UTC offset.
Worked Examples
Example 1: Killzone Schedule for UTC+5 (Pakistan)
Problem:A trader in Pakistan (UTC+5) wants to know all killzone times and plan their trading day.
Solution:Asian KZ: 5:00 AM - 9:00 AM PKT London Open KZ: 12:00 PM - 3:00 PM PKT NY Open KZ: 5:00 PM - 8:00 PM PKT London Close KZ: 8:00 PM - 9:00 PM PKT NY PM Session: 11:00 PM - 1:00 AM PKT
Result:Best windows: London Open (12-3PM) & NY Open (5-8PM PKT)
Example 2: Killzone Status Check at 2:30 PM UTC
Problem:It is currently 2:30 PM UTC. Which killzone is active?
Solution:Asian KZ (0-4 UTC): Closed London Open KZ (7-10 UTC): Closed NY Open KZ (12-15 UTC): ACTIVE (30 min remaining) London Close KZ (15-16 UTC): Upcoming in 30 min NY PM (18-20 UTC): Upcoming in 3.5 hours
Result:NY Open Killzone is ACTIVE | London Close starts in 30 min
Frequently Asked Questions
What are ICT Killzones in forex trading?
ICT Killzones are specific time windows during the trading day when institutional traders and algorithms are most active, creating the highest probability trading setups. Identified by the Inner Circle Trader (Michael J. Huddleston), the main killzones include the Asian Killzone (7-11 PM EST), London Open Killzone (2-5 AM EST), New York Open Killzone (7-10 AM EST), and London Close Killzone (10-11 AM EST). During these windows, the majority of daily high and low formations occur, stop hunts are executed, and significant price displacement happens. Trading exclusively during killzones helps filter out low-probability setups that occur during dead zones.
Why is the New York Open Killzone considered the most important?
The New York Open Killzone (approximately 7-10 AM EST / 12-15 UTC) is considered the most important because it represents the highest volume trading period in the forex market. During this window, US institutional traders enter the market alongside still-active London traders, creating maximum liquidity and volatility. The daily high or low is frequently formed during this killzone. Additionally, major US economic data releases occur at 8:30 AM EST, which falls within this window and often triggers the day's primary directional move. ICT methodology places special emphasis on this killzone because it provides the clearest evidence of institutional order flow and smart money accumulation or distribution.
How do you trade the London Open Killzone?
The London Open Killzone (2-5 AM New York time, which is 07:00-10:00 UTC while New York is on standard time) is traded by first identifying the Asian session range established overnight. When London opens, institutional traders often sweep one side of the Asian range (taking liquidity above the highs or below the lows) before establishing the true London direction. To trade this killzone, mark the Asian session high and low, then wait for a sweep of one side followed by a market structure shift in the opposite direction. Enter on a Fair Value Gap or Order Block that forms during the displacement. Place your stop loss beyond the sweep point and target the opposite side of the Asian range or the next significant liquidity level. The London killzone sets the tone for much of the trading day.
What is the significance of the London Close Killzone?
The London Close Killzone (10-11 AM EST / 15-16 UTC) marks the transition from the London/New York overlap to the New York afternoon session. This killzone is significant because London-based institutional traders are closing their positions, which can create counter-trend moves or acceleration of the existing trend. It is often the window where the daily high or low completes if it was not established during the London or NY open killzones. ICT traders use this killzone to identify exhaustion moves, trap setups, and position themselves for the NY PM session. Trades taken during London close often have shorter duration and tighter targets compared to the major killzones.
Should you trade during every Killzone?
No, you should not trade during every killzone. ICT methodology emphasizes selectivity and patience. The most effective approach is to focus on one or two killzones that fit your schedule and trading style. Many ICT traders focus exclusively on the New York Open Killzone due to its high probability. Additionally, not every killzone produces a tradeable setup — you should only enter when you identify specific conditions: a clear higher timeframe bias, a liquidity sweep at a key level, a market structure shift, and a Fair Value Gap or Order Block for entry. Trading every killzone leads to overtrading, increased commissions, and emotional decision-making. Quality over quantity is the cornerstone of profitable killzone trading.
Why do the killzone times shift by an hour twice a year?
UTC never observes daylight saving, but New York and London both do. These windows are pinned to UTC, so 12:00 to 15:00 UTC is 7 to 10 AM New York time during winter and 8 to 11 AM once the US moves onto daylight time. Because North America and Europe switch over on different dates, the usual five-hour gap between London and New York briefly narrows to four each spring and autumn. If a killzone suddenly looks an hour out of place, that is the reason.
What is the Silver Bullet window and how does it fit inside a killzone?
The Silver Bullet is a one-hour sub-window rather than a separate session, the best known version being the 10 to 11 AM New York hour, which lands where the London close overlaps the New York morning. A killzone is a two to three hour envelope in which a setup may appear; the Silver Bullet narrows attention to the single hour where displacement and a fair value gap most often form. Traders who cannot sit through a whole killzone use it to concentrate screen time.
Why do these windows use UTC instead of my broker's server time?
The windows here are held in UTC and converted to whichever offset you select. Your trading platform's clock is a third thing again: many MetaTrader brokers run servers on UTC+2 or UTC+3 so the week produces five daily candles closing at the 5 PM New York cut-off. That means daily candle boundaries and killzone boundaries can sit on different clocks. Check your platform's server time once, note the fixed difference from UTC, and stop assuming the two agree.
What happens in the dead zones between killzones?
The stretches between killzones — the late Asian hours, the midday New York lull, the tail of the US afternoon — are where ranges form rather than trends. Volume thins, spreads widen, and price tends to consolidate inside the levels set during the previous window. That consolidation is not wasted time: the Asian range built through the quiet overnight hours is precisely the pool of liquidity the London killzone later sweeps. Dead zones build the setup instead of delivering it.
How do I handle a killzone that falls overnight in my own timezone?
The timer prints a plus one day marker when a window rolls past local midnight. At UTC+9, for instance, the NY PM session at 18:00 to 20:00 UTC arrives at 3 to 5 AM the next morning. Two things follow from that. Your local calendar day and the trading day are not the same thing when you journal trades, and the killzones worth specialising in are the ones landing in your waking hours. Pick one or two you can genuinely attend.
