What time do the forex sessions open and close in São Paulo time?

On a São Paulo clock, by the conventional windows this site uses: In mid-January: Sydney 18:00 to 03:00 the next day; Tokyo 21:00 to 06:00 the next day; London 05:00 to 14:00; New York 10:00 to 19:00. In mid-July: Sydney 19:00 to 04:00 the next day; Tokyo 21:00 to 06:00 the next day; London 04:00 to 13:00; New York 09:00 to 18:00. The windows are a convention, each the business day of its own city, and not an official timetable. Public holidays are not taken into account.

When do the London and New York sessions overlap in São Paulo time?

On a São Paulo clock the London and New York windows are both open from 10:00 to 14:00 in mid-January and from 09:00 to 13:00 in mid-July. For a few weeks around the clock changes in March and in late October the hours differ by one hour, because Britain and the United States do not change on the same day.

Why did the New York session time change on my clock when my country has no daylight saving?

Because New York changed. The window is kept in New York time, and the United States moves its clocks forward in March and back in November. On a clock that stays put, the whole New York window is an hour earlier for those months. The same happens with London, on slightly different dates.

In local time

The four sessions and the main exchanges.

The region lies within a few hours of New York’s clock, so the New York window covers most of the local working day. London has been open since the small hours and closes around the middle of the day; the hours when both are open fall in the local morning or around midday.

Sydney and Tokyo open in the late afternoon or evening and trade through the local night.

ScheduleSource: the timetable this site’s clocks useWorked out for 15 January and 15 July 2027, with the time-zone rules known when the page was built. Regular weekday hours; public holidays and early closes are not shown. “+1” means the window ends on the next day of that clock.

The four sessions are conventions: each is roughly the business day of its own city. Foreign exchange has no opening bell. The exchanges are real venues with published hours, and the row for each shows its regular session only.

Two at once

The hours when two sessions overlap.

When two windows are open together, the dealers of two financial centres are at their desks at once. More participants usually means more trading, though not on every day and not in every instrument, and it says nothing about which way a price will move.

The FX week, as this site counts it, opens on Sunday at 19:00 and closes on Friday at 19:00 in mid-January, and opens on Sunday at 18:00 and closes on Friday at 18:00 in mid-July, on a São Paulo clock.

The FX week, as this site counts it, opens on Sunday at 16:00 and closes on Friday at 16:00 in mid-January, and opens on Sunday at 15:00 and closes on Friday at 15:00 in mid-July, on a Mexico City clock.

Counted from the same windows as the tables above, for the same two days. Individual brokers set their own opening and closing times for the week.

Daylight-saving time

Why the hours shift twice a year.

Brazil stopped changing its clocks in 2019 and most of Mexico in 2022. Argentina, Colombia and Peru do not change theirs. Chile still does, in the southern pattern: forward in the southern spring, back in the southern autumn.

On a clock that does not change, the New York window arrives an hour earlier from March to November, and the London window an hour earlier from late March to late October. The two countries change on different weekends, so for a few weeks in spring and about a week in autumn the gap between London and New York is an hour shorter than usual.

Each session window is kept in the local time of its own city. When that city moves its clocks forward for summer, its window starts an hour earlier in UTC, and so an hour earlier on every clock that did not move with it.

The dates differ. The United States and Canada change on the second Sunday of March and the first Sunday of November; Britain and the European Union on the last Sunday of March and the last Sunday of October; Sydney, in the southern hemisphere, goes the other way, forward in October and back in April. Tokyo does not change at all.

So the timetable has two long settled stretches each year and a few short in-between weeks. The tables on this page show the two settled stretches. The dial shows today, whichever it is.

Governments change these rules from time to time. The dial reads the rules held by your own device; a national time service is the authority.

Holidays

The kinds of day markets close.

1 January and 25 December close exchanges across the region.
Carnival, in February or March, closes Brazil’s exchange. Its dates move each year with Easter, as do Good Friday and Corpus Christi.
Each country’s independence day closes its own exchange: 7 September in Brazil and 16 September in Mexico, for example.
Other national and religious holidays differ from country to country, and several are moved to a Monday by law.

Foreign exchange has no single exchange and no single holiday calendar. On 25 December and 1 January almost every financial centre is shut and little or nothing trades. On other holidays one centre is away and the rest carry on, usually with fewer participants; brokers publish their own hours for those days.

Stock, futures and commodity exchanges are different: each one closes on its own country’s public holidays and publishes its calendar, with any shortened days, well ahead. That calendar is the only reliable list. The clocks and tables on this site show regular weekday hours and know nothing of holidays.

Not advice

Questions to ask about tax.

This site gives no tax or legal advice, and this page states no rule, rate or threshold for any country. How trading is taxed differs from country to country and from person to person. What follows is a list of questions to take to a qualified adviser or to your tax authority, which is where the answers are.

1Where I live, is a gain from trading treated as income, as a capital gain or as something else? Does the answer depend on how often I trade?
2Does the kind of product change the answer: a spot position, a contract for difference, a future, an option, a share?
3Can a loss be set against gains? Against other income? Carried forward to a later year?
4When is a gain or a loss counted: when a position is closed, at the end of the tax year, or when money is withdrawn?
5Which records must I keep, in what form and for how long?
6Will the statements my broker provides be enough, or is something more needed?
7How are costs treated: spreads, commission, overnight financing, data, software?
8In which currency do I report, and which exchange rate do I use to convert?
9Do I have to report an account held with a firm abroad, even in a year with no gain?
10When and how do I declare, and when is payment due?
11Does my situation change any of this: resident or not, employed or self-employed, trading in my own name or through a company?

The same list appears on every region guide, because the questions are the same everywhere. Only the answers differ.

An explanation of a timetable. It is not advice, and the hour of the day says nothing certain about what a price will do.

Trading foreign exchange on margin carries a high level of risk, and may not be suitable for all investors. The high degree of leverage can work against you as well as for you. Before deciding to trade foreign exchange you should carefully consider your investment objectives, level of experience, and risk appetite. The possibility exists that you could sustain a loss of some or all of your initial investment and therefore you should not invest money that you cannot afford to lose.
