Backtest USDJPY — Candle by Candle, Free
USDJPY is the trend-follower's pair — it can run for weeks on rate differentials, then reverse violently when the Bank of Japan steps in. Backtesting it on real historical price is how you learn to ride the trend without getting caught by the shock.

Why backtest USDJPY?
The yen trends more cleanly than most majors, which makes trend and continuation setups genuinely testable on it. But it also carries intervention risk — the BoJ can spike it hundreds of pips in minutes. Backtesting shows you both sides: how your setup performs in the trend, and how badly the outlier days hurt.
Knowing your real drawdown on USDJPY before you trade it means the violent days don't surprise you — you've already seen what they do to your equity curve in replay.
What makes USDJPY different to backtest
USDJPY is driven by interest-rate differentials, risk sentiment and carry — when the dollar is strong and risk is on, it tends to grind higher steadily. It's most active across the Asian and New York sessions, and it moves on both Fed and Bank of Japan policy.
There's a quirk that trips up a lot of traders: on JPY pairs a pip is 0.01 (the second decimal), not 0.0001, and the pip value drifts with the exchange rate. The position size calculator adjusts for that automatically, so your USDJPY backtests reflect the right dollar risk.
