The London breakout is one of the simplest day-trading strategies to understand, and its timing is convenient for UK traders because it happens on our doorstep: the start of the London session. The idea is that the quiet overnight (Asian) session often forms a tight range, and the arrival of London traders can push price out of that range with momentum.

This page gives you a complete, written rule set you can backtest and practise on a demo account, plus an honest look at where it goes wrong.

The idea behind the strategy

The forex market trades around the clock, but activity isn’t evenly spread. The UK is the world’s largest centre for foreign exchange trading, with around 38% of global FX turnover according to the Bank for International Settlements’ 2025 survey (BIS). As London desks open, volume and volatility typically pick up compared with the overnight session.

The London breakout tries to catch that shift:

1. Mark the high and low of the Asian session – the overnight range.
2. Wait for price to break out of that range around the London open.
3. Enter in the direction of the break with a stop on the other side (or in the middle) of the range.
4. Take profit at a fixed multiple of your risk, or close by a set time.

It’s popular because the rules are objective. There’s no guessing whether a level is “strong” – the range is the range.

The catch: many breakouts fail. Price pokes above the range, triggers buy orders, then reverses. Your rules must accept that a good proportion of trades will lose, and keep each loss small.

The rules (a complete beginner version)

These are example rules for learning and backtesting. They aren’t the only way to trade a London breakout, and you should test any changes before using them.

1. Market and chart

• Pick one pair. GBP/USD is a natural choice for UK traders.
• Use a 15-minute chart set to UK time (check your platform’s time-zone setting).

2. Define the Asian range

• Mark the highest high and lowest low between 00:00 and 06:59 UK time.
• Draw horizontal lines at both. This is your range.

3. Range filter (skip bad days)

• Skip the day if the range is unusually wide. As a starting rule, skip if the range is more than half of the pair’s 14-day Average True Range (ATR) on the daily chart. A wide range means a wide stop and less room left to run.
• Skip the day if a major scheduled release for either currency is due between 07:00 and 10:00 UK time (check an economic calendar). Many UK data releases come out at 07:00.
• Skip UK and US bank holidays and the days between Christmas and New Year, when liquidity is thin.

4. Entry

• At 06:59, place:
• a buy stop order a few pips above the range high (a buffer for the spread – e.g. 2–3 pips on GBP/USD), and
• a sell stop order the same distance below the range low.
• Use a one-cancels-the-other (OCO) order if your platform has it. Otherwise, cancel the opposite order manually as soon as one is filled.
• Entry window: 07:00–10:00 UK. Cancel any unfilled orders at 10:00.

5. Stop-loss

Choose one method and stick to it in testing: – Option A (conservative): stop at the opposite side of the range. – Option B (tighter): stop at the midpoint of the range.

Option B means smaller losses per trade and a better risk-to-reward ratio, but you’ll be stopped out more often.

6. Take-profit and exit

• Target: 2R – twice the distance from entry to stop.
• Time exit: if neither stop nor target is hit, close the trade at 16:00 UK time. The idea is to trade the London move, not hold overnight.
• One trade per day. If you’re stopped out, you’re done for the day. No reversing, no re-entry.

7. Position size

• Risk a fixed 0.5–1% of your account per trade. Work out your stake from the stop distance (see “Risk management” below).

Worked example (hypothetical)

All prices are made up for teaching. This isn’t a real trade or a forecast.

Setup: Demo account of £10,000. Risk 1% = £100 maximum. GBP/USD, 15-minute chart, spread bet (stake per pip).

1. Asian range (00:00–06:59): high 1.3040, low 1.3010. Range = 30 pips.
2. Filter: 14-day ATR is 90 pips; half is 45. The range (30) is under 45, so the day is valid. No major GBP or USD news before 10:00.
3. Orders at 06:59: – Buy stop at 1.3043 (3 pips above the high) – Sell stop at 1.3007 (3 pips below the low)
4. Stop method: midpoint of the range = 1.3025. – For the long: entry 1.3043 → stop 1.3025 = 18 pips of risk.
5. Position size: £100 ÷ 18 pips = £5.55 per pip. Round down to £5 per pip. Actual risk = 18 × £5 = £90.
6. Target (2R): 2 × 18 = 36 pips above entry = 1.3079.
7. What happens: At 08:20 price breaks above 1.3043 and the buy stop fills. The sell stop is cancelled.

Outcome A – target hit: Price reaches 1.3079 at 11:40. Profit = 36 × £5 = +£180 (+2R).

Outcome B – fakeout: Price fills at 1.3043, stalls, then falls back into the range and hits 1.3025. Loss = 18 × £5 = −£90 (−1R). You stop for the day.

Outcome C – neither by 16:00: Price drifts to 1.3055. You close at 16:00 for +12 pips = +£60 (+0.67R).

Notice what keeps this manageable: the loss in Outcome B was decided before entry, and it’s only 0.9% of the account.

Risk management

Position sizing formula (spread bet):

Stake per pip = (account × risk %) ÷ stop distance in pips

Always round down. If the result is below your provider’s minimum stake, the trade is too big for your account – skip it.

Other risk rules for this strategy: – Maximum one trade a day. Breakout days that fail often whipsaw both ways. Reversing after a loss doubles your exposure to a messy day. – Spread check. If the spread at 07:00 is much wider than normal, wait or skip. The spread is part of your risk. – Weekly loss limit. For example: stop for the week after three losing trades (−3R). Breakout strategies can lose several days in a row. – No moving stops further away. You can move a stop to break-even at +1R if your tested rules say so, but never widen it.

Learn the maths properly in Position sizing step by step and The 1% rule.

Using it in a prop firm challenge

If you’re considering a prop firm challenge, the London breakout has some useful features – and some traps.

What fits well: – One defined trade a day makes it easy to stay inside a daily loss limit. – Fixed risk per trade fits maximum drawdown rules. – Trades close the same day, which helps with firms that restrict holding positions overnight or at weekends.

What to watch: – News rules: some firms restrict trading around high-impact news. 07:00 UK releases can clash with your entry window. Check the firm’s rules. – Minimum trading days and consistency rules: a “skip the day” filter is good discipline but can slow you down. Don’t loosen your filter to hit day counts. – Losing streaks vs drawdown: if your challenge allows a 10% maximum drawdown and you risk 1% per trade, ten losses in a row ends the challenge. Losing runs of that length do happen with breakout strategies. Many traders risk less (e.g. 0.5%) in challenges for this reason.

Before paying for any challenge, run the strategy on a demo account under the firm’s exact rules. Use the True Cost Calculator to see what repeated attempts would cost, and compare firms’ rules – especially daily loss limits and whether drawdown is trailing or static.

Common mistakes

1. Trading every day regardless of conditions. The range filter and news filter are there to keep you out of poor setups.
2. Using the wrong time zone. If your platform runs on server time (often GMT+2/+3), your “Asian range” will be wrong. Check, and remember UK clocks change in March and October.
3. No buffer for the spread. Orders placed exactly at the range high get triggered by spread noise.
4. Chasing a missed breakout. If the move happened without you, let it go. Entering late means a worse price with the same stop.
5. Reversing after a fakeout. “It failed upward, so I’ll sell” is an untested strategy and often a revenge trade.
6. Widening the stop because the range was big. Wide range = skip the day, not bigger risk.
7. Changing the rules after two losses. You need a large sample before judging (see below).

How to backtest the London breakout

Backtesting means applying your exact rules to past charts and recording the results honestly. See What is backtesting? for the full method.

1. Use bar replay. In TradingView (or similar), go back at least 12 months and replay day by day so you can’t see what happens next.
2. Record every valid day, including the days the filter told you to skip (mark them “skipped” with the reason).
3. Log these columns: date, range high, range low, range size, ATR, direction, entry, stop, target, result in R, exit reason (target/stop/time), spread at entry (estimate), notes.
4. Aim for at least 100 trades before drawing conclusions. Twenty trades tells you almost nothing.
5. Include costs. Subtract a realistic spread from each trade. Breakout systems are sensitive to costs.
6. Track the longest losing streak. It’s as important as your average result, because it tells you how much drawdown to expect.
7. Test one change at a time – e.g. midpoint vs opposite-side stop – and record both versions separately.

Then move to demo forward testing for at least 60 days with the same rules. Record every trade in your trading journal.

Variations to test later (one at a time)

• Range window: 23:00–06:59 instead of 00:00–06:59.
• Frankfurt-only range: 07:00–08:00 as a “pre-London” range, entering on the break after 08:00.
• Target: 1.5R vs 2R vs a trailing stop.
• Trend filter: only take breakouts in the direction of the daily 50-period moving average (see Moving average pullback strategy).
• Other pairs: EUR/USD or EUR/GBP. Don’t trade several pairs at once until you’ve tested each – GBP pairs often move together, which multiplies risk (Correlation risk).

FAQ

What time is the London breakout in UK time? The London session is usually treated as starting at 08:00 UK time, though activity often picks up from around 07:00 as European markets open. The rules above use 07:00–10:00 as the entry window.

Which pair is best for the London breakout? There’s no “best”. GBP/USD and EUR/USD are commonly used because they’re liquid during London hours. Test one pair thoroughly rather than looking for the perfect one.

Does the London breakout strategy still work? We don’t publish performance claims. Results vary by market conditions, rules and costs, and past results don’t predict future ones. Backtest it yourself over at least 100 trades, including costs, and then forward test on demo.

Is this a good strategy for beginners? It’s beginner-friendly because the rules are objective and there’s only one trade a day. That doesn’t make it profitable or safe – false breakouts and losing streaks are common.

Can I automate it? The rules are simple enough to automate, but don’t run anything automated until you understand it fully and have tested it manually. Some prop firms restrict automated trading.
