Trading Sessions Explained: London, New York, and Asian Session Breakdown

The market does not move equally throughout the day. Understanding which session you are in changes everything about how you trade.

Financial markets operate 24 hours a day, five days a week. But the 24-hour cycle is not a uniform block of activity. It is divided into three major trading sessions, each with its own character, volatility profile, institutional participants, and typical price behaviour. Trading the wrong strategy in the wrong session is one of the fastest ways to destroy an edge that works perfectly at the right time.

Session	Hours (EST)	Characteristics	Best Pairs
Asian (Tokyo)	7 PM – 4 AM	Lower volatility, tighter ranges, sets liquidity for London	USD/JPY, AUD/USD, AUD/JPY
London	3 AM – 12 PM	Highest forex volume, strongest directional moves, most BOS events	EUR/USD, GBP/USD, EUR/GBP, Gold
New York	8 AM – 5 PM	High volatility during London overlap, US data releases, major moves	EUR/USD, GBP/USD, USD/CAD, Gold, NQ, ES
London-NY Overlap	8 AM – 12 PM	Peak volume. Highest probability window in all of forex.	All major pairs. Maximum liquidity.

The Three Major Sessions

Asian Session (Tokyo): 00:00–09:00 UTC

The Asian session is the lowest-volatility major session. Average daily ranges for EUR/USD during Asian hours are typically 30-40% of the full daily range. Liquidity is thinner, moves are slower, and the session tends to establish a range rather than create directional movement.

For ICT traders, the Asian session is critical not for trading but for planning. The Asian range — the high and low established during these hours — becomes the liquidity pool that London and New York will target. The Power of 3 accumulation phase occurs during Asia. Mark the Asian session high and low on your chart every single day.

Instruments most active during Asia include USD/JPY, AUD/USD, NZD/USD, and the Nikkei 225. Crypto markets also see significant Asian session volume due to the concentration of exchange activity in the region.

London Session: 07:00–16:00 UTC

London is the world’s largest financial centre. Approximately 43% of all daily forex volume flows through London. The session open is the single most important time of the trading day for most currency pairs because it is when the largest wave of institutional orders hits the market.

The London open typically creates the day’s directional bias. In the Power of 3 model, London executes the manipulation phase by sweeping one side of the Asian range, then begins the distribution phase. If London sweeps the Asian low, the daily bias is likely bullish. If it sweeps the Asian high, bearish.

The ICT London killzone runs from 07:00 to 10:00 UTC. This is when the highest-probability setups form. Volatility expands dramatically compared to Asia, spreads tighten due to increased liquidity, and institutional algorithms begin executing their daily programs.

New York Session: 12:00–21:00 UTC

New York is the second-largest session by volume and often produces the day’s largest single move. The most important period is the London-New York overlap from 12:00 to 16:00 UTC, when both financial centres are active simultaneously. This window consistently produces the highest volume and the most significant price moves of the 24-hour cycle.

The ICT New York killzone runs from 12:00 to 15:00 UTC. Key US economic releases hit at 12:30 or 13:00 UTC, often creating the volatility that drives the distribution phase of the day’s Power of 3 structure.

After 16:00 UTC, London closes and New York volume begins to thin. The final hours of the New York session are typically lower volatility, similar to the Asian session, and represent the beginning of the next day’s accumulation phase.

The London-New York Overlap: Where the Money Is

The overlap period from 12:00 to 16:00 UTC consistently produces more volume, more volatility, and more significant price deliveries than any other four-hour window. If you can only trade one session, this is it. EUR/USD, GBP/USD, and US equity indices are most active during this window.

The overlap often delivers the New York continuation or reversal of the London move. If London established a bullish bias, New York frequently retests the London session low before continuing higher. Understanding this pullback-continuation pattern during the overlap is one of the highest-probability intraday setups available.

Session-Specific Strategies

Each session rewards a different approach. Asian session strategies should focus on range-bound setups, mean reversion from the extremes of the developing range, and marking key levels for the London session. London session strategies should focus on breakout plays from the Asian range, liquidity sweeps, and establishing the daily directional bias. New York session strategies should focus on continuation of the London bias, reversal setups when New York counters London, and economic news-driven volatility plays.

The biggest mistake traders make is applying a trend-following strategy during Asia or a range strategy during London’s open. The same setup that produces a clean trend trade at 08:00 UTC produces a stop-hunt at 02:00 UTC. Time context is not optional. It is a core component of every trade decision.

Practical Application: Building a Session-Based Routine

If you trade the London and New York sessions, your daily routine should follow this structure. Before London opens, mark the Asian session high and low, identify the previous day’s high, low, and close, note any significant economic releases scheduled for the session, and identify the nearest liquidity pools above and below current price.

During the London killzone, watch for the sweep of the Asian range, identify the displacement candle and resulting FVG, and enter if the setup aligns with the daily bias from higher timeframe analysis. During the New York session, reassess whether New York is continuing or reversing London, watch for the overlap pullback-continuation setup, and manage existing positions through the highest-volume window.

Frequently Asked Questions

Which trading session is best for beginners?

The New York session (8 AM to 5 PM EST) offers the highest volume during the London-New York overlap and the most directional moves. Most ICT educators recommend starting here because setups are clearest during peak liquidity. If your timezone makes New York difficult, the London session is an excellent alternative.

Can I trade during the Asian session?

The Asian session typically has lower volatility and tighter ranges on major forex pairs. It is better used as a reference period: mark the Asian high and low, then trade the liquidity sweep of those levels during London or New York Kill Zones. For crypto and JPY pairs, the Asian session can be more active.

What is the London-New York overlap?

The period from roughly 8 AM to 12 PM EST when both London and New York are actively trading. This is the highest-volume window in forex markets and typically produces the largest directional moves of the day. Many professional traders focus exclusively on this overlap for their highest-probability setups.

Do sessions matter for crypto trading?

Crypto trades 24/7, but institutional participation still follows traditional session hours. Bitcoin and Ethereum see their highest volume during London and New York sessions. The Asian session can also be significant for crypto because of exchanges like Binance and OKX. Apply Kill Zone logic but expect slightly more activity outside traditional windows.

How do I adjust session times for my timezone?

Convert from New York (EST/EDT) to your local time. London Open Kill Zone is 2-5 AM EST (7-10 AM London). New York Open Kill Zone is 7-10 AM EST. Use a world clock app or the timezone converter on your charting platform. Write your Kill Zone times in local time and post them at your trading desk so you never miscalculate session boundaries.
