How Long Is London Session Trading? Hours and an AI Case

The full London forex session lasts nine hours. Learn how its local schedule differs from the ICT Kill Zone, with daylight-saving conversions and a club AI paper trade.

LSG Club · 5 October 2026 · 9 min read

The answer to “how long is london session trading” is nine hours under the common London-local convention: for example, 08:00–17:00 on a weekday. That schedule normally converts to 03:00–12:00 in New York and 10:00–19:00 in Kyiv, with a temporary New York shift during daylight-saving transition weeks. Use the LSG Club trading journal to record whether you traded the full session or the shorter ICT London Kill Zone.

How long is London session trading from open to close?

The full session describes London's forex business day. Spot forex has no central opening bell, so these boundaries are a convention rather than exchange-enforced opening and closing times. This article uses the London-local timetable example of 08:00–17:00, a nine-hour window.

A shorter session box on another chart may reflect a different convention or a strategy's entry window. Check its start, end and reference time zone before comparing results. London's session ending also does not mean weekday forex trading stops; other financial centres remain active.

London: keep the schedule on the local clock

In this timetable example, London opens at 08:00 and closes at 17:00 in both winter and summer. Winter uses Greenwich Mean Time, while summer uses British Summer Time. The local hours stay constant; their UTC equivalents change.

Winter example: 08:00–17:00 London equals 08:00–17:00 UTC.
Summer example: 08:00–17:00 London equals 07:00–16:00 UTC.

New York: usually early morning through noon

For the same schedule example, London runs from 03:00 to 12:00 New York local time when both cities use standard time or both use daylight time. That is 3 a.m. to noon Eastern Time. Use ET as the general label: EST is winter standard time, and EDT is summer daylight time.

Kyiv: late morning through evening

Under the current seasonal clock rules, Kyiv stays two hours ahead of London, so the schedule example is 10:00–19:00 Kyiv local time. Both cities change clocks on the same dates in the calendar example below. Recheck local rules when planning a future year rather than treating an old conversion as permanent.

Daylight-saving changes that move your trading window

The United States changes clocks earlier in spring and later in autumn than the United Kingdom. During those gaps, London is four hours ahead of New York rather than the usual five. For the full-session example used here, New York hours temporarily become 04:00–13:00; the London-local duration remains nine hours.

For a calendar example, in 2026 the UK changes clocks on March 29 and October 25, while the US changes on March 8 and November 1. The affected weekday trading periods are March 9–27 and October 26–30. These conversion periods follow from the clock-change dates.

In that calendar example, Kyiv also changes clocks on March 29 and October 25. Its full-session conversion therefore stays 10:00–19:00. A New York-anchored Kill Zone behaves differently, because its reference clock is American.

The full London session versus the ICT London Kill Zone

For the ICT framework used here, the London Kill Zone is 02:00–05:00 New York local time. It is a three-hour entry-analysis window around early European activity, distinct from the full London forex session. A Kill Zone identifies when to look for a setup; it does not supply the setup.

Normal clock alignment example: the London Kill Zone is 07:00–10:00 London and 09:00–12:00 Kyiv.
Transition-week example: the same New York window becomes 06:00–09:00 London and 08:00–11:00 Kyiv.
UTC conversion examples: 06:00–09:00 when New York uses daylight time; 07:00–10:00 when it uses standard time.

Notice that the Kill Zone can begin before the conventional full-session opening. Keep separate chart labels and journal tags for each. The ICT Kill Zone timing guide explains how these entry windows fit into a session-based routine.

Liquidity means resting orders, including stops, above swing or equal highs and below swing or equal lows. A sweep trades through a marked level and closes back inside. A break that holds beyond it is not automatically a sweep. Read the liquidity sweep entry explanation before treating a session-opening spike as confirmation.

How to mark London hours on TradingView

Use an intraday chart and keep the displayed chart clock separate from the time zone used to calculate a session overlay. Changing the chart clock changes time labels; an overlay may still use its own configured reference zone. Check both settings before relying on a shaded session box.

Select your chart's display time zone through the clock or chart settings.
For a manual example, set the display to London and draw vertical boundaries at 08:00 and 17:00, shading the interval between them.
If using a configurable session overlay, enter the full-session example of 08:00–17:00 with Europe/London as its reference zone.
Mark the ICT London Kill Zone separately at 02:00–05:00 with America/New_York as its reference zone.
Check a normal week and a daylight-saving transition week to confirm that each box follows the intended clock.

Named regional zones adjust for daylight saving; fixed UTC offsets do not. Label each box with its purpose so you can distinguish the full business session from your permitted entry period.

Case study: the club's AI London Kill Zone paper trade

On Monday, 2026-10-05, the club's AI tracked a short on DAX (GER40) as a live paper trade using real-time bars and no real money. It used one of the club's entry rules. GER40 is an index instrument, so this example illustrates timing discipline rather than defining forex or index trading hours.

The analysis called for waiting

The club's AI had a short bias but a decision to wait. Price had touched a fair value gap, yet the planned new bearish market structure shift had not occurred. The H4 and D1 views conflicted, and a short from 25268.10 toward the nearest liquidity offered only 1.65R.

25329.50: the untaken Asian-session high and an H1 swing high.
25299.50: the protected high of the bearish M15 structure.
25268.10: the midpoint of the bearish M15 fair value gap.
25202.90: the nearest untaken equal lows and an H1 swing low.

The local short idea was invalidated by an M15 close above 25299.50. Acceptance above 25329.50 required a new scenario and did not automatically authorize a long. Being inside the Kill Zone does not override a wait decision or an invalidation condition.

An MSS requires price, after taking liquidity, to break the last swing that led into the sweep with displacement: strong, fast candles that leave a fair value gap. A bearish FVG is the three-candle gap between candle one's low and candle three's high. The MSS confirmation and entry rules explain why timing and structural confirmation need separate checks.

The paper entry and actual exit

The entry concept was a limit entry after a liquidity sweep of a marked pool; the paper fill was recorded as a market short. The liquidity taken was the Asian-session high at 25329.50. Keep the entry concept and the actual execution type separate when reviewing this trade.

Filled: 2026-10-05 at 06:15 UTC, or 02:15 New York time, at 25329.10.
Stop: 25345.10. Target: 25202.90. Planned reward-to-risk: 7.89R.
Closed: 2026-10-05 at 06:30 UTC, or 02:30 New York time, at 25345.10.
Outcome: lost, with a recorded result of -1.01R and best favourable excursion of 1.06R.

Both entry and exit were inside the London Kill Zone. The entry preceded the conventional full London session opening. The stop ended the trade; the target was not reached. Its favourable excursion shows that price moved in the intended direction before the loss, but does not establish that a different management rule would have produced a profit.

Applying an example session-exit deadline

For example, a separate rule could require cancelling unfilled entry orders and closing any remaining position at 05:00 New York time, the end of the London Kill Zone. That is an illustrative deadline, not the reason this paper trade closed. Its stop had already ended the position at 02:30.

Write an entry cutoff and a position-exit rule separately. Ending the entry window does not automatically require closing an existing position unless your plan says so. Define that decision before entering, using the ICT trading plan template to document it.

Build a session routine you can review

Choose the window that matches your tested setup and availability. You do not need to watch the entire London business day to trade a London setup. Before the window, check the relevant economic calendar, mark liquidity and record your directional conditions.

Record the trade date, instrument, UTC timestamp and reference time zone.
Tag full London session and London Kill Zone separately.
Save the planned entry condition, invalidation, stop, target and time-exit rule.
Afterward, record the actual fill, exit reason and result in R, including decisions to wait.

Review whether you followed the same timing convention each day before comparing outcomes. The ICT trading journal fields help make those comparisons consistent. Trading is risky, losses happen, and this article is education, not financial advice.

Common London session timing mistakes

Calling all Eastern Time EST: use New York local time and let seasonal conversion distinguish EST from EDT.
Treating a fixed UTC box as London-local all year: its relationship to London's clock changes seasonally.
Confusing a Kill Zone with the full session: label the business-session window and the strategy window separately.
Entering because the session opened: a timestamp cannot replace a liquidity raid and required structural confirmation.
Moving the exit deadline after entry: record changes explicitly rather than quietly extending a losing trade.
Applying forex hours to GER40 availability: check your broker's current instrument schedule and holiday notices.

FAQ

How long does a London session go for?

Under the common London-local convention, it lasts nine hours; the timetable example is 08:00–17:00. The ICT London Kill Zone used here lasts three hours, from 02:00–05:00 New York time. State which window you mean when discussing London trading.

What time is the London trading session in the US?

For the full-session timetable example, it is normally 03:00–12:00 Eastern Time and temporarily 04:00–13:00 during US–UK daylight-saving mismatch weeks. Elsewhere in the US, convert the date-specific London hours to your local regional time zone.

Does daylight saving make the London session shorter?

No. The London-local business-session convention keeps the same duration. What changes is its position on another time zone's clock. A New York-anchored Kill Zone also retains its duration while shifting relative to London during transition weeks.

Must I close a London trade when the Kill Zone ends?

Only if your trading plan requires it. An entry window and a holding deadline serve different purposes. For example, a plan could require being flat at 05:00 New York; another tested plan could allow holding afterward. Record the rule before entry.
