How Forex Trading Sessions Work
The forex market operates 24 hours a day, five days a week, across four major trading centers: Sydney, Tokyo, London, and New York. Each session has distinct characteristics - the pairs that move, the average range, and the typical trading volume. Understanding when sessions open and overlap is essential for timing entries and managing risk.
| Session | Opens (UTC) | Closes (UTC) | Active Pairs |
|---|---|---|---|
| Sydney | 22:00 | 07:00 | AUD/USD, AUD/JPY, NZD/USD, AUD/NZD |
| Tokyo | 00:00 | 09:00 | USD/JPY, EUR/JPY, GBP/JPY, AUD/JPY |
| London | 08:00 | 17:00 | EUR/USD, GBP/USD, EUR/GBP, EUR/JPY |
| New York | 13:00 | 22:00 | EUR/USD, GBP/USD, USD/JPY, USD/CAD |
Trading the London-New York Overlap
The London-New York overlap (13:00-17:00 UTC / 8 AM-12 PM EST) is the highest-volume window in forex - over 50% of daily volume occurs here. Spreads tighten to their minimum on EUR/USD, GBP/USD, and USD/JPY. If you trade only one session, this is the one. Use the spread cost calculator to see how much tighter ECN spreads get during this window.
Sydney-Tokyo: The Asian Power Window
The Sydney-Tokyo overlap (00:00-07:00 UTC) drives AUD and NZD pairs. AUD/JPY and NZD/USD see their best range during these hours. For yen pairs, the Tokyo session alone (00:00-09:00 UTC) often sets the day's range. Check the ATR calculator to compare typical ranges during Asian vs London hours.
The Danger Zone: Tokyo-London Gap
Between 08:00-09:00 UTC, Tokyo winds down as London opens - but only for one hour. This is the thinnest liquidity window. Spreads widen, slippage increases, and pairs like EUR/JPY can gap. Most traders avoid entering new positions during this transition unless playing the London breakout deliberately.
