The New York forex session is the heartbeat of North American currency trading and a cornerstone of the global 24-hour forex market. For traders who operate in Greenwich Mean Time (GMT), understanding exactly when the New York session opens and closes—and how it interacts with other sessions—is essential for managing volatility, liquidity, and risk. This guide explains the New York session's GMT timing, its role in the forex week, how to use it effectively, and the risks that come with trading during America's trading hours.
The New York forex session is the period during which the North American financial markets are open for trading. In the forex market, it represents one of the four major trading sessions—alongside Sydney, Tokyo, and London. The session is defined by the operating hours of the New York Stock Exchange and the broader US financial system, with trading dominated by institutional players, hedge funds, and retail traders operating from the Eastern time zone.
In GMT (Greenwich Mean Time), the New York session runs from 13:00 to 22:00 during standard time (Eastern Standard Time, or EST). During Eastern Daylight Time (EDT), which the US observes from the second Sunday in March through the first Sunday in November, the session shifts one hour earlier to 12:00–21:00 GMT. This seasonal change is a critical detail for any trader who tracks the forex market in GMT.
The New York session is the second-largest forex session by volume, following the London session. According to the Bank for International Settlements (BIS) Triennial Central Bank Survey, trading activity in the New York session accounts for roughly 20–25% of global daily forex turnover, with the USD involved in approximately 90% of all transactions. This makes the New York session indispensable for any trader who deals in US dollar pairs.
The New York session operates within the context of the global forex trading day. Because forex trades over-the-counter (OTC) through a global network of banks, brokers, and electronic trading platforms, the session is defined by the collective activity of market participants in the Eastern time zone, rather than a centralised exchange.
At 13:00 GMT (08:00 EST), the New York session opens, and there is a four-hour overlap with the London session, which runs from 08:00 to 17:00 GMT. This overlap—13:00 to 17:00 GMT—is the most liquid and volatile period of the entire trading day. It is during this window that the two largest forex centres (London and New York) are simultaneously active, generating the highest trading volumes and the tightest spreads.
The New York session is famous for US economic data releases. Key reports such as Non-Farm Payrolls (NFP), Consumer Price Index (CPI), Gross Domestic Product (GDP), retail sales, and the Federal Open Market Committee (FOMC) interest rate decisions are typically published during the session. These announcements can trigger sharp price movements that range from 50 to over 200 pips in a matter of minutes.
At 22:00 GMT (17:00 EST), the New York session closes. There is a brief period of reduced activity as the US markets wind down, and the Asian session (starting with Tokyo) does not begin until 00:00 GMT. This one-hour gap (22:00–00:00 GMT) is often characterised by lower liquidity and wider spreads, making it a period to be cautious about.
The New York session is the primary session for US economic releases. The CFTC's retail forex education materials emphasise that these announcements can cause rapid, unpredictable price swings. Traders must be prepared for sudden spikes in volatility, which can lead to significant profits but also to substantial losses if positions are not managed carefully.
The 13:00–17:00 GMT overlap is the most liquid window globally. During this period, the BIS Triennial Survey indicates that the spread on major pairs like EUR/USD can narrow to as little as 0.1–0.2 pips for institutional players. Retail traders also benefit from tighter spreads and faster execution.
The New York session is the home of the US dollar. All major USD pairs (EUR/USD, USD/JPY, GBP/USD, USD/CHF) see their highest volume during this session. USD/CAD also tends to be particularly active, reflecting the close economic ties between the US and Canada. Emerging-market currencies paired with USD can also move significantly, especially when risk sentiment shifts.
The New York session often sets the tone for the rest of the 24-hour trading cycle. A strong US economic report can lift the USD across the board, influencing the Asian session that follows. Conversely, a weak report can trigger a risk-off mood that persists until the next session.
The high liquidity and volatility of the London-New York overlap make the New York session ideal for intraday strategies. Scalpers and day traders can exploit rapid moves around US data releases and the session open.
The New York session is the primary window for US economic data, making it the preferred session for news traders who specialise in trading around NFP, CPI, and FOMC announcements.
US-based importers, exporters, and multinational corporations use the New York session to execute hedges, as they can trade during their normal business hours and receive real-time pricing.
Portfolio managers and hedge funds often use the New York session to adjust positions based on US market sentiment, taking advantage of the liquidity to rebalance USD exposures.
When deciding whether to trade during the New York session—and how to approach it—consider the following evaluation criteria:
Evaluate your own time zone. Trading during the New York session is most suitable if you are based in or can operate during US Eastern Time hours. If you are in Asia, for example, the New York session falls during your late night or early morning, which may not be ideal for active trading.
The New York session is known for sharp, fast moves. Assess your risk appetite and your ability to handle rapid drawdowns. If you are a conservative trader, you may prefer to avoid trading immediately around major data releases.
The New York session is punctuated by high-impact news events. You should always check the economic calendar before placing trades. The CFTC and NFA both recommend that retail traders familiarise themselves with the timing and potential impact of scheduled data releases.
Not all brokers offer the same execution quality during the New York session. Some may widen spreads during volatile news events or restrict stop-loss placement. Verify your broker's terms, as the Federal Reserve's exchange-rate materials indicate that market-making practices can vary significantly.

GMT times are based on standard time (EST). During EDT (mid-March to early November), the New York session shifts one hour earlier to 12:00–21:00 GMT, and the overlap shifts to 12:00–16:00 GMT. Sources: BIS Triennial Survey, industry practice.
Scenario: A swing trader based in London monitors the New York session to take advantage of directional moves after US data releases. On a Thursday, the US CPI report is scheduled for 13:30 GMT, and the trader expects that a higher-than-expected reading will strengthen the USD.
Action: The trader sets an alert on EUR/USD and waits for the 13:30 release. The CPI prints 0.4% vs. 0.3% expected, and EUR/USD drops sharply from 1.1050 to 1.0980 within 15 minutes. The trader enters a short position at 1.0985 with a stop-loss at 1.1015 and a take-profit at 1.0930.
Outcome: The pair continues to drift lower over the next two hours, hitting the take-profit level at 1.0930. The trader captures 55 pips, using the New York session's volatility to their advantage. They then step aside as liquidity begins to thin after 17:00 GMT.
Note: This is a hypothetical illustration for educational purposes only. Past performance is not indicative of future results.
Reality: The 13:00 GMT opening applies during Eastern Standard Time (roughly November to March). During Eastern Daylight Time (roughly March to November), the session opens at 12:00 GMT. Many traders forget to adjust their clocks, leading to missed entries or inaccurate backtesting.
Reality: US data releases are staggered. NFP and CPI are typically at 13:30 GMT, while GDP and retail sales often come at 13:30 as well. However, some reports like the FOMC statement can come at 18:00–19:00 GMT. Check the calendar for exact timings.
Reality: While USD pairs are dominant, the New York session also sees significant volume in cross pairs like EUR/GBP, EUR/JPY, and GBP/JPY, especially during the overlap with London.
Reality: While the overlap ends at 17:00 GMT, the New York session continues to trade until 22:00 GMT (17:00 EST). There is still volume, especially from US-based institutional desks, but liquidity gradually declines. The final hour or two (21:00–22:00 GMT) can see thinner conditions.
Reality: The New York session has its own character. It is driven more by US news and corporate flows, while the London session is often driven by European data and offshore flows. The two sessions have distinct rhythms, and traders should adapt their strategies accordingly.
The New York session is characterised by high volatility, especially around US economic data releases. The CFTC's Retail Forex Fraud Advisory emphasises that off-exchange forex trading is extremely risky, and that retail investors can lose all of their invested capital in a matter of minutes if they are not prepared. The rapid price movements that are common during the New York session can be both an opportunity and a serious danger.
