Why the same pair behaves completely differently at 3am and 3pm.

The forex market never closes during the week, but that does not mean every hour is worth trading. This lesson maps the trading day so you can choose hours that suit your pairs and your schedule.
Equity markets have an opening bell. Forex has a relay: as one financial centre closes, another opens, and the market is handed westward around the globe.
| Session | Approximate hours (UTC) | Dominant currencies |
|---|---|---|
| Sydney | 21:00 – 06:00 | AUD, NZD |
| Tokyo | 00:00 – 09:00 | JPY, AUD, NZD |
| London | 07:00 – 16:00 | EUR, GBP, CHF |
| New York | 12:00 – 21:00 | USD, CAD |
Exact hours shift with daylight saving in each region, which is why a session tracker that adjusts automatically is more useful than a memorised table.
Work in UTC
Every serious FX schedule — economic calendars, session tables, broker rollover times — is published in UTC or New York time. Get comfortable converting once, and a whole category of "why did that release come out an hour early?" confusion disappears.
Volume is not spread evenly. It concentrates where sessions overlap, because that is when two regions' participants are both active.
London–New York (roughly 12:00–16:00 UTC) is the single most important window of the trading day. Both of the largest FX centres are open simultaneously, most high-impact US and European data is released in it, and the majority of the daily range on EUR/USD and GBP/USD is typically set during it.
Tokyo–London (roughly 07:00–09:00 UTC) is a smaller overlap, notable for the European open pushing into whatever range Asia has built overnight.
Sydney–Tokyo (roughly 00:00–06:00 UTC) is the quietest stretch for the majors, but it is when AUD, NZD and JPY pairs are most active and when Australian, New Zealand, Japanese and Chinese data lands.
Your strategy has a time of day. A breakout strategy needs volatility to break out into; running it at 03:00 UTC on EUR/USD, in the middle of a dead Asian range, will produce a stream of false signals. A range-fading strategy has the opposite problem — it works in exactly those quiet hours and gets destroyed at the London open.
Spreads widen when liquidity thins. Around the daily rollover (typically 21:00–22:00 UTC) spreads on many pairs widen noticeably as banks square positions. Placing a market order in that window costs more than it does an hour either side.
Trade the session that matches your pair. If you can only trade during the Asian session, look at AUD, NZD and JPY pairs rather than forcing EUR/GBP to be interesting. The pair and the hour should agree.
The market closes Friday evening and reopens Sunday evening (UTC), but the world does not stop over the weekend. News that lands between those two points is priced in at the open, which can appear as a gap. It is usually small on the majors, and it is a real reason to be careful holding a large position over a weekend.
Be honest about your schedule before you choose a style. A strategy that requires you to be at a screen for the London open is worthless if you are commuting at that hour. It is much easier to pick a style that fits your life than to reorganise your life around a style.
Three workable patterns:
The third is genuinely underrated for anyone with a job.
What to remember
The trading day is a relay between Sydney, Tokyo, London and New York. Volatility concentrates in session overlaps, above all London–New York, and thins to almost nothing in the Asian session for major pairs. Your strategy, your pairs and your available hours all need to agree with each other.
