- Open the simulator and pick USD/JPY from the instrument list - or EUR/JPY, GBP/JPY, AUD/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.

The data
Sixteen years of dollar-yen, already loaded.
Tick-derived OHLC bars from the same archive our published research is computed on. Lower timeframes cover shorter windows because the underlying data is far denser - the table is exactly what you can replay today.

From 2019 to 2021 the typical dollar-yen day covered 50 to 56 pips. From 2022 to 2025 it covered 114 to 120 - more than double - as the rate gap between the Fed and the Bank of Japan reopened and the yen fell to multi-decade lows. A USD/JPY strategy built on 2019-2021 data has stops sized for a market that no longer exists. Test across the break, and read the two halves separately before you trust the total.
The hourly profile has a quirk the European pairs do not. The single busiest hour outside the London-New York overlap is 00:00 UTC - the Tokyo open at 09:00 local - at 24.3 pips, slightly above the London open at 07:00 UTC (21.9 pips). A breakout system that ignores the Asian session is skipping one of the yen's two real opens.

Questions
USD/JPY backtesting FAQ
Is USD/JPY backtesting really free here?
Yes. USD/JPY and all 105 instruments are unlocked on the free plan, with every timeframe, full trade execution and the session report. Nothing to download, no card. Paid plans add more saved sessions, more simultaneous indicators and deeper analytics - not the USD/JPY chart or its history.
How much USD/JPY history can I replay?
Daily and 4-hour bars from June 2010 and hourly from July 2010. 30-minute data starts in July 2018, 15-minute in July 2022, 5-minute in April 2025 and 1-minute in April 2026.
How volatile is USD/JPY now?
Far more than before 2022. The median day covered 50 to 56 pips from 2019 to 2021 and 114 to 120 pips from 2022 to 2025; so far in 2026 it is 82 pips.
Can I backtest other yen pairs?
Yes. EUR/JPY, GBP/JPY, AUD/JPY, CAD/JPY, CHF/JPY, NZD/JPY and ZAR/JPY are on the same free plan with the same replay engine and report - all listed on the backtest hub.
