The Asian session runs from roughly 23:00 to 08:00 UTC and tends to range rather than trend. What genuinely moves in it is the yen, the Australian and New Zealand dollars, and anything reacting to Japanese, Australian or Chinese data. Its most valuable output is not a trade — it is the overnight range London opens against.
The standard advice is to skip these hours because they are quiet. That is half right and entirely unhelpful. Quiet is a description of volatility, not of opportunity, and a session that reliably builds a clean range is in some ways easier to plan for than one that reliably explodes. The mistake is not trading the Asian session. The mistake is trading it as if it were London.
The three centres behind one label
“The Asian session” is shorthand for three financial centres that open in sequence, not a single market with a bell.
| Centre | Approximate hours (UTC) | What it brings |
|---|---|---|
| Sydney | 22:00 – 07:00 | The week’s first prices. Thin, wide, easy to misread. |
| Tokyo | 00:00 – 09:00 | The yen, Japanese exporters and importers, the 9:55 JST fix. |
| Hong Kong & Singapore | 01:00 – 10:00 | The deepest regional liquidity and China-linked flow. |
The hours that matter are the Tokyo–Hong Kong overlap, broadly 01:00 to 06:00 UTC. Before it, you are trading on Sydney liquidity alone; after it, you are waiting for London. Every time in this table shifts by an hour when daylight saving changes in one hemisphere and not the other — the full mechanics are in forex sessions explained.
How much of the market is actually awake
This is worth grounding in numbers rather than feel, because the region is far larger than its reputation for being quiet suggests.
Global OTC foreign exchange turnover reached $9.6 trillion per day in April 2025, up 28% from $7.5 trillion in 2022, according to the BIS Triennial Central Bank Survey. Within that, Singapore accounted for 11.8% of turnover and Hong Kong 7.0% — and the Bank of Japan reports Japanese turnover of $440.2 billion per day in the same month (Bank of Japan, April 2025 survey). The same BIS survey found the yen on one side of 16.8% of all currency trades.
Two conclusions follow, and they pull in opposite directions. The region is a genuine share of the world’s largest market, so the idea that “nothing trades in Asia” is simply wrong. But it is still comfortably smaller than the UK’s roughly 38% share, and that gap is exactly why a EUR/USD chart can look asleep for six hours and then travel its entire overnight range in the twenty minutes after London walks in.
What actually moves, and what only looks like it moves
Trade the pairs whose home markets are open. Everything else is drifting on residual flow.
- USD/JPY and the yen crosses. The most consistently active instruments of the session. Japanese corporate flow is genuinely present here in a way it is not at any other hour.
- AUD/USD and NZD/USD. These respond to Australian and New Zealand releases and, increasingly, to Chinese data — the Australian dollar is the liquid way the market expresses a view on China.
- AUD/JPY. The classic regional risk barometer, because it pairs a commodity currency against a funding currency inside a single session.
- EUR/USD and GBP/USD. Present, priced, and mostly waiting. Their Asian ranges are narrow and their breakouts during these hours fail more often than they resolve.
The scheduled events that reliably produce a move are Australian employment and inflation data, RBA and RBNZ rate decisions, Bank of Japan decisions, and the Chinese data batch — trade balance, CPI and PPI, GDP. There is also the Tokyo fix at 9:55 a.m. JST, a daily benchmark rate against which a lot of Japanese corporate business is transacted, and which can put a directional push into USD/JPY in the minutes before it that has nothing to do with your chart pattern. How to sit around scheduled events generally is covered in how news events move forex pairs.
Why it ranges, and what that does to your setups
The session ranges because the participants who move price in size — European and American banks, funds and corporates — are mostly not at their desks. What is left is regional flow, which is real but narrower, and it produces a market that respects levels and rarely runs through them.
That single fact reorganises your whole playbook:
- Breakout setups get worse. A break with no follow-through is the session’s signature behaviour. Requiring a candle to close beyond the level and hold matters more here than anywhere.
- Mean-reversion setups get better. Range edges that get rejected tend to get rejected again, for the simple reason that nothing large enough to overwhelm them shows up.
- Targets shrink, so costs matter more. Spreads widen in thin hours while your realistic target shrinks. A two-pip spread against a fifteen-pip target is a completely different business from a two-pip spread against a sixty-pip target — the arithmetic is in what is the spread in forex.
- Position size should come down, not up. Thinner books mean worse fills when you are wrong, which is precisely when fills matter.
Three playbooks that fit the session
In rough order of how often they are available.
- Fade the range edge on rejection. Mark the high and low once the Tokyo overlap has been running an hour. When price reaches an edge and prints a rejection, trade back toward the middle with the stop beyond the extreme. Target the midpoint, not the far side. This is the same logic as the range day playbook, applied to a session instead of a day.
- Trade the scheduled release, on the retest. An RBA decision or a Chinese trade number produces a genuine expansion out of the range. Do not chase the first candle; wait for the break to hold and retest, which is the entry described in what is a retest.
- Build the range and hand it over. Do not trade at all. Mark the 23:00–07:00 high and low and take that map into the European open, where the false break through one side is one of the most durable setups in forex — the full treatment is in how to trade the London open.
The third option is a real strategy, not a cop-out. For a trader in a European time zone the Asian session is the preparation and London is the trade.
Who this session actually suits
Being honest about the fit matters more than talking it up.
It suits traders in Asia-Pacific time zones trading their own hours; traders in Europe or the Americas who hold a day job and can only sit down late or very early; and anyone whose temperament is better served by four hours of patience than by twenty minutes of speed. The trade-offs are real and worth naming: wider spreads, smaller ranges, and long stretches where the correct action is none. If you need the market to move to stay engaged, this session will bore you into taking a trade you did not plan, which is the failure mode described in the discipline of sitting on your hands.
It is also the wrong session for large-target swing entries on the majors. If your plan needs a sixty-pip run to work, take it to the hours where the volume is.
Frequently Asked Questions
What time is the Asian trading session?
Roughly 23:00 to 08:00 UTC, though it is really three overlapping centres rather than one session. Sydney opens first at around 22:00 UTC, Tokyo follows at about 00:00 UTC, and Hong Kong and Singapore come in near 01:00 UTC. The densest hours are the Tokyo–Hong Kong overlap, broadly 01:00 to 06:00 UTC. Daylight saving shifts every one of these by an hour.
Which currency pairs move most in the Asian session?
The pairs whose home markets are open: USD/JPY and the yen crosses, AUD/USD, NZD/USD and AUD/JPY. These respond to Japanese, Australian, New Zealand and Chinese data released during those hours. EUR/USD and GBP/USD usually drift in a narrow range until London arrives, which is why fading their Asian range so often looks easy and so often is not.
Is the Asian session good for beginners?
It suits a specific temperament rather than a specific experience level. Ranges are smaller, spreads are wider and moves are slower, which rewards patience and punishes traders who need action. If you hold a day job in a European or American time zone, the Asian session is often the only one you can trade properly, and trading one session properly beats trading three badly.
What is the Asian range and how do traders use it?
The Asian range is the high and the low set between roughly 23:00 and 07:00 UTC. It is the session’s most useful output. London traders mark it before the European open and watch for the false break through one side that reverses and runs the other way, because the stops resting beyond a well-defined overnight range are the easiest liquidity in the day to reach for.
Bottom line
The Asian session is not the quiet corner of the forex day so much as a different kind of market: smaller, slower, more respectful of levels, and concentrated in the yen and the commodity dollars. Trade it by matching the setup to the conditions — fade rejections at range edges, wait for the retest after a scheduled release, and require a hold on every break. And if you take nothing else from these nine hours, take the range. The high and the low it prints are the most useful two lines on a London trader’s chart.
