Forex trading generally runs from about 3 p.m. Sunday to 3 p.m. Friday in New Mexico, with trading available through much of the weekday cycle. The London and New York session overlap usually falls between 6 a.m. and 10 a.m. Mountain Time. During short periods when the United States and United Kingdom change their clocks on different dates, that overlap extends to 11 a.m.
Those hours are planning guides, not a guarantee that your account will accept orders every minute. Broker maintenance, holidays and the currency pair can affect availability. This guide covers retail spot forex timing; currency futures and other exchange traded products can follow different schedules.
When Does Forex Open and Close in New Mexico?
The common weekly reference is Sunday at 5 p.m. through Friday at 5 p.m. New York time. Subtract two hours to convert that schedule to New Mexico time. This matches the published Cboe FX Spot trading hours, although an individual retail broker’s opening and closing times may differ.
For a normal trading week, use these local reference points:
- Sunday around 3 p.m.: the weekly trading window begins.
- Monday through Thursday: trading generally continues around the clock, subject to platform breaks.
- Friday around 3 p.m.: the weekly trading window ends.
- Saturday: ordinary retail spot forex trading is closed.
New Mexico remains two hours behind New York through both standard time and daylight saving time. That makes the Sunday and Friday conversion relatively simple. The harder part is converting overseas sessions, because London, Sydney and Tokyo do not all follow the same clock changes.
If you are still comparing currency trading with other ways to invest, start with the broader forex trading guide for New Mexico residents. Knowing the opening time does not tell you whether the product suits your finances or risk tolerance.
Mountain Standard Time Versus Mountain Daylight Time
New Mexico uses Mountain Standard Time, or MST, at UTC−7 during standard time and Mountain Daylight Time, or MDT, at UTC−6 during daylight saving time. “Mountain Time,” abbreviated MT, can refer to either, depending on the date.
In 2026, the US daylight saving period runs from March 8 to November 1. The recurring rule is the second Sunday in March through the first Sunday in November, with changes at 2 a.m. local time. The NIST daylight saving schedule confirms those dates.
A clock labelled “MST” may mean a fixed UTC−7 offset rather than a clock that adjusts with New Mexico. During summer, that fixed clock will be one hour behind local time. Where a platform offers a location based setting, select a Mountain Time location that observes daylight saving rather than assuming every “Mountain” option behaves alike.
Forex Session Hours in New Mexico Mountain Time
The following table converts a stated set of local business hour windows: 8 a.m. to 5 p.m. for Sydney, London and New York, and 9 a.m. to 6 p.m. for Tokyo. These are session planning conventions, not official opening bells. Spot forex does not stop everywhere because one financial center finishes its working day.
| Trading center | Local reference window | New Mexico winter: MST | New Mexico summer: MDT |
|---|---|---|---|
| Sydney | 8 a.m. to 5 p.m. | 2 p.m. to 11 p.m. | 4 p.m. to 1 a.m. the next day |
| Tokyo | 9 a.m. to 6 p.m. | 5 p.m. to 2 a.m. the next day | 6 p.m. to 3 a.m. the next day |
| London | 8 a.m. to 5 p.m. | 1 a.m. to 10 a.m. | 1 a.m. to 10 a.m. |
| New York | 8 a.m. to 5 p.m. | 6 a.m. to 3 p.m. | 6 a.m. to 3 p.m. |
Seasonal exceptions matter. The winter column assumes London is on Greenwich Mean Time and Sydney is on Australian Eastern Daylight Time. The summer column assumes London is on British Summer Time and Sydney is on Australian Eastern Standard Time. During transition periods, London or Sydney can move one hour away from the displayed window.
For Sydney and Tokyo, the Australian or Japanese business date is ahead of New Mexico. Tokyo’s Monday morning session therefore begins on Sunday evening locally. Likewise, Tokyo’s Friday session begins on Thursday evening in New Mexico. Do not add an extra Asian session on Friday evening after your broker has closed for the weekend.
Why London Hours Shift During March and October
London usually stays seven hours ahead of New Mexico, but not throughout the year. The United States starts daylight saving earlier in March and finishes later in the fall. In 2026, the UK government’s clock change calendar lists March 29 and October 25 as the British change dates.
That creates two exceptions for the London window used here:
- March 9–27, 2026: London’s 8 a.m. to 5 p.m. window converts to 2 a.m. to 11 a.m. in New Mexico.
- October 26–30, 2026: the same London window again converts to 2 a.m. to 11 a.m.
- Other ordinary trading days in 2026: it converts to 1 a.m. to 10 a.m.
New York’s reference window remains 6 a.m. to 3 p.m. locally. The calculated London–New York overlap is therefore normally four hours, from 6 a.m. to 10 a.m., and five hours during those mismatch periods.
This extra hour comes from different clock settings, not an extension to the global trading week. If you use session alerts, review them around both countries’ clock changes rather than changing everything on the US date alone.
Why Sydney and Tokyo Need Different Conversions
Sydney follows the opposite season
Sydney observes daylight saving during the Southern Hemisphere’s warmer months. Its clock changes do not line up with New Mexico’s. New South Wales began daylight saving on October 4, 2026, and ends that period on April 4, 2027, under the published New South Wales daylight saving schedule.
For the 8 a.m. to 5 p.m. Sydney window used in the table, there are three possible New Mexico conversions: 2 p.m. to 11 p.m. when New Mexico is on MST and Sydney is on daylight time; 4 p.m. to 1 a.m. when New Mexico is on MDT and Sydney is on standard time; and 3 p.m. to midnight when both observe daylight saving.
A Sydney business hour window also does not establish when your broker opens on Sunday. Your account’s published schedule controls when you can submit an executable order.
Tokyo stays on the same offset
Tokyo uses Japan Standard Time at UTC+9, maintained through the NICT Japan Standard Time service. Tokyo does not make a seasonal clock change, so its session moves by one hour on a New Mexico clock when New Mexico changes between MST and MDT.
This makes Tokyo easier to track than Sydney. Using the table’s reference window, the local opening moves from 5 p.m. in winter to 6 p.m. during daylight saving time. The Japanese working hours themselves have not changed.
Which Forex Hours Are Worth Studying?
For someone researching major currency pairs, the London–New York overlap is a practical observation window. Historical Reserve Bank of Australia research on intraday currency trading found that turnover and volatility were highest during that overlap in the pairs studied. It also found bursts of activity around economic releases.
That supports studying the overlap, not treating it as an automatic trading advantage. Higher activity can bring more price movement, but more movement can mean faster losses. A busy chart is not a generous chart.
For a New Mexico resident working normal daytime hours, 6 a.m. to 8 a.m. may be a more manageable research period than the London opening at 1 a.m. Evening availability may fit the Tokyo window better. Choose a period you can monitor consistently rather than one that requires chronic sleep deprivation.
The pair also matters. Use the guide to forex currency pairs to identify which economies and currencies your trade involves. Then examine that pair during your available hours, rather than assuming a session label describes every pair equally well.
Convert Economic Releases Before Setting Alerts
Session timing is only part of the schedule. A planned announcement can change trading conditions within a session, so record both the trading window and the events that fall inside it.
The US Employment Situation report and Consumer Price Index are scheduled at 8:30 a.m. Eastern Time on their release dates, which converts to 6:30 a.m. in New Mexico. Check the actual dates on the Bureau of Labor Statistics release calendar; do not assume every release follows the same weekday pattern.
That distinction matters if your trading window starts at 6 a.m. A plan to watch the first hour of New York activity may also place you directly across a major announcement. Decide beforehand whether your plan permits holding a position through scheduled news.
Set your economic calendar to local Mountain Time and verify one event against its original published time. If the calendar already converts the release to New Mexico time, subtracting another two hours will produce a very punctual mistake.
Rollover, Maintenance and Holiday Hours
The daily rollover reference commonly centers on 5 p.m. New York time, or 3 p.m. in New Mexico. This is a trading date boundary, not a universal weekday shutdown. The CME Group EBS trading schedule lists a 5 p.m. Eastern trade date roll for standard spot instruments and different arrangements for some other products.
For your account, confirm the financing cutoff, any maintenance pause and whether orders remain active during that pause. Do not assume the platform’s chart timestamp is your local clock, or that its daily candle closes at midnight in New Mexico.
Holding through the broker’s financing cutoff may produce a debit or credit under the account terms. Compare that cost separately from the spread and commission using the guide to forex spreads, commissions and financing. A trade opened shortly before a cutoff needs the same cost check as one held all day.
Holidays need a separate review. A normal weekly schedule does not establish holiday availability, and the holiday calendar of a stock exchange is not a reliable substitute for your forex broker’s notice. Check the instrument, date and stated time zone before converting any revised hours.
Before a weekend closure, decide whether carrying the position fits your risk plan. You may not be able to close it while ordinary trading is unavailable. Do not rely on a stop order as a guarantee of execution at its stated price if the market reopens beyond that level.
Build a Schedule Around the Hours You Can Monitor
Start with one observation window rather than trying to cover Sydney, Tokyo, London and New York. Record your chosen pair, the local start and finish times, scheduled announcements and any position management deadline.
For example, an Albuquerque resident studying EUR/USD before work could reserve 6 a.m. to 7:30 a.m., check for a 6:30 a.m. release, and decide in advance what happens to any open position when monitoring ends. This is a scheduling example, not a trading recommendation. The same routine should still work on days when no acceptable trade appears.
Use a demo account to check that session indicators, alerts and chart times match your intended local window. The guide to what forex demo accounts can and cannot teach you covers the difference between practicing a routine and reproducing live trading conditions.
The most useful schedule is one you can follow without guessing about the clock. Keep the approximate 3 p.m. Sunday opening and Friday closing as weekly reference points, verify overseas session conversions around clock changes, and check your broker’s actual availability before placing an order.
