New York session in forex trading explained

What is New York session?

The New York session refers to the period when US financial centres are open and quoting prices in the spot foreign exchange market. It begins around 8am Eastern Time, when interbank desks in New York staff up alongside Chicago futures venues, and closes around 5pm ET, which also marks the daily rollover point used by most brokers. The session captures US data releases, Federal Reserve communications, and Wall Street equity flows. Because the US dollar sits on one side of roughly nine in ten spot FX trades, the New York session sets the tone for global currency pricing during its active hours.

How traders use New York session

Retail traders typically organise the day around the London to New York overlap, broadly 8am to 12pm ET, when both centres are quoting and order books are deepest. Spreads on majors tighten, slippage on stop orders falls, and intraday ranges expand. Institutional desks cluster execution into this window for the same reason: best fills on size. US data prints, including non-farm payrolls, CPI and FOMC statements, land inside the New York morning at 8:30am or 2pm ET, producing the bulk of the day’s directional moves. After the London close around 12pm ET, liquidity thins, ranges narrow, and price action often drifts or fades the morning move into the 5pm rollover.

Common misconceptions about the New York session

A frequent mistake is treating the full 8am to 5pm ET window as uniformly active. In practice, the high-liquidity phase ends when London closes around 12pm ET, after which volume drops sharply and ranges compress. Another misconception is that the New York session drives all USD pairs equally; in reality, USD/JPY often sees its largest moves during the Tokyo to London handover, while EUR/USD and GBP/USD respond most aggressively during the overlap. Finally, the 5pm ET close is not a hard stop, it is the daily rollover where swap is applied and liquidity briefly evaporates.

Frequently asked

What time does the New York session open and close?

The New York session runs from approximately 8am to 5pm Eastern Time, which corresponds to 1pm to 10pm London time during British Summer Time, or 2pm to 11pm during Greenwich Mean Time. The 5pm ET close also marks the daily forex rollover, when swap charges are applied and liquidity briefly dries up before the Sydney and Tokyo desks take over for the next trading day.

Which currency pairs are most active during the New York session?

EUR/USD, GBP/USD and USD/JPY see the highest activity, particularly during the London overlap from 8am to 12pm ET. USD/CAD also becomes more active because Canadian data releases align with the US schedule. Commodity-linked pairs such as AUD/USD and NZD/USD remain liquid but tend to peak during the Asian session, with US hours often producing reversals or continuation moves tied to dollar flows.

Why is the London to New York overlap considered the best time to trade?

The overlap, roughly 8am to 12pm ET, is the only period when the two largest FX centres are simultaneously open. Combined order flow produces the tightest spreads of the day, the deepest liquidity for large orders, and the widest intraday ranges. Most scheduled US data releases land inside this window, giving traders both volatility and the execution conditions to act on it without excessive slippage.

Does the New York session matter for traders outside the US?

Yes. Because the US dollar features in the majority of global FX transactions, the New York session influences pricing across every major pair regardless of where the trader is based. European traders often work the overlap before their evening, while Asian traders frequently set alerts for US data releases. The session’s price action also sets the reference levels that Tokyo and Sydney desks trade around the following morning.
