Full explanation

The Asian session covers roughly 00:00 to 08:00 UK time, with Tokyo the dominant centre and Sydney opening earlier. Volumes are lower than in London or New York, so many pairs move within a relatively narrow range.

JPY, AUD and NZD pairs are the exception: their domestic data and central-bank decisions land in this session and can produce significant movement.

The range built overnight matters to European traders even if they never trade it. The Asian high and low are frequently the first levels tested when London opens.

Why traders watch it

Knowing what happened overnight sets the context for the day: whether the market is coiled in a tight range, or already moving on Asian-hours news.

Session Summaries record how the Asian session behaved so the following Trading Plan starts from evidence rather than assumption.

Trading considerations

  • Expect smaller ranges and wider spreads outside JPY, AUD and NZD pairs.
  • Mark the overnight high and low before London opens.
  • A large Asian range often signals genuine news, not just noise.
