- Open the simulator and pick GBP/JPY from the instrument list - or GBP/USD, USD/JPY, EUR/JPY and the rest of the 105.
- Choose a start date and timeframe. The chart hides everything after it, so you read the same bars a trader had at the time rather than a chart you already know the answer to.
- Replay bar by bar and place trades with the mouse. Drag the stop and target on the chart and the lot size follows from your risk percent.
- Read the report. Win rate, expectancy, profit factor, Sharpe and drawdown across the session, saved to your trading journal so the sample accumulates.

4,237 GBP/JPY daily bars, 2010-06-29 to 2026-09-25, FxBacktest archive, weekend stubs excluded; the all-years row covers the whole archive.
The nickname is earned. The median GBP/JPY day covers 130.6 pips against 78.8 on EUR/USD, and in 2024 the gap reached 2.63 times - 145.7 pips a day against 55.4. A 30-pip stop that is reasonable on EUR/USD sits well inside a normal pound-yen hour. Size the stop from GBP/JPY's own range and let the lot size shrink to match, rather than keeping the lot and widening the risk.
The tails are where the pair earns its reputation. 35.4% of days range more than 1% of price, against 21% on EUR/USD, and 24 June 2016 covered 13.7% from high to low. A sample that includes the referendum week can be carried by it - check the result with and without that week.

Guide
Let the lot follow the stop
On a pair this wide, a fixed lot size turns into a variable risk. Size from the stop distance so each trade risks the same share of the account.

Where GBP/JPY sits against the majors and the other crosses, and what that means for stop and target sizing.
Read the guide GuideEnough trades per regime
Split the sample by year before you trust the total. Each regime needs enough trades on its own to mean something, or the headline win rate is mostly one good year.
