With about 38% through the UK and 19% through the US, **the London morning and its New York overlap are busiest**. Where forex trades share of daily turnover, 2022 Source: Bank for International Settlements, Triennial Survey 2022, rounded. Two countries, in practice London and New York, carry **more than half of all the trading**. - **Cost.** More buyers and sellers means tighter spreads. - **Follow through.** A move in a busy session has orders behind it. - **Which pairs move.** A currency moves most while its home centre is open. DT Terminal Charts GBPUSD · H1 One GBPUSD day, with each session's open marked. Watch the volume bars under the candles: thin through Asia, heavy from the London open and through the overlap, thin again into the rollover. **Go deeper** The shares come from the Bank for International Settlements' 2022 survey of forex trading. Currencies trade between banks, funds, companies and brokers all over the world, which is why there is no single exchange. The three reasons in more detail. Cost: the same `EURUSD` trade can cost a fraction of a pip at 10:00 London and several pips at rollover. Follow through: the same move in a quiet hour often drifts and comes back. Which pairs move: a currency moves most while its home centre is open and its own data comes out, `JPY`, `AUD` and `NZD` in Asia, `EUR` and `GBP` in London, `USD` in New York. The same chart can be dead at one hour and moving fast three hours later. Knowing the clock tells you which of the two you are looking at. Chapter 2 of 6 ## The trading day in your time The timeline shows each session in your time. The gold band is the overlap, London and New York both open. The red dashed line is the 17:00 New York rollover; the gold line is now. Interactive tool ### Sessions timeline This interactive tool runs in the app, with your own numbers. [Continue in the app, free](https://www.thedtterminal.com/login?signup=true&redirect=%2Fjournal%2Facademy%2Fmarket-sessions%3Fsection%3Dyour-clock%23your-clock) Free account Japan never changes its clocks. The UK and the US do, on different dates, so **sessions shift on your clock during the year**. Keep the session clock open The Sessions tab in Calculators shows which sessions are open now, in your time. Worked example ### Example 01: One London open, two clocks The worked example, with every number walked through, is in the app. [Continue in the app, free](https://www.thedtterminal.com/login?signup=true&redirect=%2Fjournal%2Facademy%2Fmarket-sessions%3Fsection%3Dyour-clock%23your-clock) Free account **The exact hours and the clock changes** The example is a Wednesday in July: London is on summer time, and Singapore stays on UTC+8 all year. Check the Sessions tab before you open a chart. Each bar is a session at its own city's hours: Tokyo 09:00 to 18:00 Tokyo time, London 08:00 to 17:00 London time, New York 08:00 to 17:00 New York time, and the US stock market 09:30 to 16:00 New York time. The US moves forward on the second Sunday in March and back on the first Sunday in November. The UK moves on the last Sunday of March and the last Sunday of October. So for two to three weeks in March, and about a week around the end of October, London is four hours ahead of New York instead of five, and the overlap runs 5 hours instead of 4. If you live somewhere with no daylight saving, every session moves an hour on your clock twice a year. In January London goes back to UTC+0, so Singapore is 8 hours ahead. The London open becomes 16:00 in Singapore and the overlap runs 21:00 to 01:00. The London trader's clock did not move. The Singapore trader's did, by an hour, because only one of the two cities changed its clocks. Chapter 3 of 6 ## What each session is like Every day is different, but each session has a familiar character. | Session | Local hours | What it is like | | --- | --- | --- | | Asia | 09:00 to 18:00 Tokyo | Usually quieter. **Often builds a range.** JPY, AUD and NZD pairs move most. | | London | 08:00 to 17:00 London | **The most volume of the day.** Big moves in EUR, GBP and gold. Often breaks the Asian range and sets the day's high or low. | | New York | 08:00 to 17:00 New York | Much of the big US data comes out at **08:30**. Moves every USD pair and gold. US stock indices open at 09:30. | | London and New York overlap | 08:00 to 12:00 New York | Usually the busiest window of the day: both of the biggest centres are open at once. | | Rollover | 17:00 New York | The trading day ends. Spreads widen sharply for a few minutes, and swap is charged on trades held through it. | **Indices follow their exchange, not the forex clock.** Volume arrives when the stock market behind them opens, and the first hour is usually one of the busiest of the day. | Index | Exchange | Cash hours | | --- | --- | --- | | Nikkei 225 | Tokyo Stock Exchange | 09:00 to 15:30 Tokyo, lunch break 11:30 to 12:30 | | DAX 40 | Frankfurt (Xetra) | 09:00 to 17:30 Frankfurt | | FTSE 100 | London Stock Exchange | 08:00 to 16:30 London | | S&P 500, Nasdaq 100, Dow | New York (NYSE, Nasdaq) | 09:30 to 16:00 New York | **Busy is not the same as good.** More volume means tighter spreads and moves that follow through, and it also means **faster moves against you**. Watch how your own pairs behave in each session before you decide which hours suit you. **Go deeper** Index CFDs often quote for most of the day, even though their volume waits for the cash open. Symbol names vary by broker. You do not have to guess which hours suit you. Plot every trade at the time of day you entered it, with its result in R, and the session your results really come from shows up on its own. Chapter 4 of 6 ## The Asian range and the London open On many days Asia moves in a narrow band until London brings the first big volume. Its high and low are the Asian range, and many traders watch how London treats them. GBPUSD · H1 the Asian range, then the London open [Replay in the app](https://www.thedtterminal.com/login?signup=true&redirect=%2Fjournal%2Facademy%2Fmarket-sessions%3Fsection%3Dasian-range%23asian-range) London time, a winter day. Illustrative candles: the point is the shape, **a narrow night and a wider morning**, not this exact day. Worked example ### Example 02: GBPUSD: the Asian range before London breaks it The worked example, with every number walked through, is in the app. [Continue in the app, free](https://www.thedtterminal.com/login?signup=true&redirect=%2Fjournal%2Facademy%2Fmarket-sessions%3Fsection%3Dasian-range%23asian-range) Free account Try it in the backtester Replay a few weeks of `GBPUSD` on H1. Mark each Asian high and low, then note what London did with them. **Go deeper** In the example the 08:00 candle closes at 1.3444, above the Asian high, and by 12:00 price reaches 1.3483: 1.6 times the night's range in four hours. A break tells you **where the levels are, not which way the day will go**. When you replay, mark the high and low before each 08:00 candle and sort what London did: broke and held, broke and reversed, or stayed inside. London often pushes through one side of the range first, takes out the stops sitting just beyond it, then reverses through the other side. Chapter 5 of 6 ## The daily rollover At 17:00 New York the forex day ends and the next one starts: the rollover. Liquidity drains for a few minutes and **spreads on most pairs widen sharply**, often to several times normal. It is also when **swap** is charged or paid on any trade held through it. Worked example ### Example 03: Why entering at rollover costs you spread The worked example, with every number walked through, is in the app. [Continue in the app, free](https://www.thedtterminal.com/login?signup=true&redirect=%2Fjournal%2Facademy%2Fmarket-sessions%3Fsection%3Drollover-and-weekends%23rollover-and-weekends) Free account **Go deeper** In the example the bid peaks at 1.08585, under the stop at 1.08620. With a 0.8 pip spread the ask peaks at 1.08593, still 2.7 pips short. With 4.5 pips it reaches 1.08630 and the stop fills. Banks settle the day's positions at rollover, which is why liquidity drains. Many brokers charge three days of swap on Wednesday's rollover to cover the weekend; the exact rates are in your broker's contract specifications. Many brokers also set their server clock so that midnight lands at 17:00 New York (GMT+2 in winter, GMT+3 in summer), which is why a daily candle in MT5 usually runs from one rollover to the next. Chapter 6 of 6 ## The weekly open and the weekend The forex week opens at about 17:00 New York on Sunday and closes at 17:00 New York on Friday. Sunday's first price can open away from Friday's close. That jump is a **gap**, and a stop inside it fills at **the first price available, not at its level**. **Crypto never closes.** Bitcoin and other coins trade every day of the year, weekends included. **Know your hours.** Before any trade, know your session, how far away rollover is, and whether the market closes before the trade is likely to finish. **Go deeper** The sessions timeline shows the open and close in your time. The world keeps moving while the market is shut, which is why the gap happens, and a trade held over the weekend carries a gap risk you cannot exit during. The exact opening and closing minutes vary a little by broker. Spreads are wide and liquidity is thin in the first minutes of the week. Weekend crypto is often thinner than weekday crypto, so moves can be sharp when few people are trading. Quick review ## Check yourself Quick review · 0 of 0 Answer these before the next lesson.
