The idea
Forex trades around the clock, but not evenly. During the Asian session the major European pairs often drift in a narrow range. When London opens at 8:00 UK time, the biggest trading centre in the world starts work and volume jumps.
The London breakout marks the high and low of the Asian session and trades the first decisive break of that range after London opens: a close above the high is a buy, a close below the low a short.
Watch it play out
Step by step
The rules
Setup
- Mark the high and low from midnight to 7:00 UK time (the Asian session).
- Skip days when the range is unusually wide.
Entry
- Buy on a close above the Asian high after 8:00, or short on a close below the low.
- Only the first break of the day.
Stop-loss
- At the middle of the Asian range, or the opposite side.
Target
- 2R, or close the trade by the New York open.
Filters that help
- Avoid days with major UK or euro area news in the first hour.
- Prefer tighter ranges: a range that is already wide leaves less room.
Why it can work
Orders build up overnight and get executed when European desks arrive. The quiet range concentrates stop orders just beyond its edges, and when London pushes through one side, those stops add fuel to the move.
Worked example
EUR/USD ranges between 1.0995 and 1.1025 overnight. At 8:00 a one-hour candle closes at 1.1036: buy, with the stop at the middle of the range, 1.1010, 26 pips away.
Risking 100 dollars, that is 0.38 lots. A 2R target sits 52 pips up, at 1.1088.
When it works, when it fails
Works best
On days with a tight Asian range and a clear catalyst in the European morning.
Struggles
On days when London breaks one side, reverses and runs to the other: a classic false breakout. It also struggles when the range is wide and the stop far away.
Common mistakes
- Trading both sides after the first break fails.
- Ignoring the size of the range: a wide range gives a poor risk to reward.
- Entering on the first touch instead of a close outside.
Variations
- Frankfurt open
- Using the hour before London (7:00 to 8:00 UK time) as the trigger window instead.
What the evidence says
Evidence: Tested, mixedPublic tests disagree, or the edge has faded over time.
The London breakout is one of the most taught forex day trading setups. Public backtests of a standard version on EUR/USD and GBP/USD over recent years show it losing money, suggesting the simple form has stopped working on those pairs, if it ever did after costs.
Hence mixed: the session behaviour it relies on is real, but the plain rules do not hold up in recent public tests.
Questions
- Where does the stop go in a London breakout?
- Commonly at the middle of the Asian range, or at its opposite side for more room. The middle gives a better risk to reward and more stop-outs; the opposite side survives more false breaks but needs a smaller position.
- What if the Asian range is very wide?
- Then the move may already have happened overnight, and the stop would be far away. Many traders skip days when the range is wider than usual, for example wider than its average over the last few weeks.
- What time is the London breakout?
- London opens at 8:00 UK time. The Asian range is usually marked from midnight to 7:00 UK time, and the breakout is traded from 8:00 onwards. Clock changes shift these against other time zones.
- Which pairs suit the London breakout?
- European pairs such as EUR/USD, GBP/USD and EUR/GBP, whose volume rises most when London opens.
- Does the London breakout still work?
- Recent public backtests of the standard version on EUR/USD and GBP/USD show losses. If you trade it, test your exact rules, including spread, on recent data.
