Forex Backtesting Software — Replay Real FX History, Free
A forex edge is a session-specific, pip-accurate thing — and most "backtesting" is just scrolling a chart and remembering the winners. Real forex backtesting software replays the market bar by bar so you can prove your edge instead of imagining it.
Why forex needs proper backtesting
Forex has a personality most tools ignore: the market has sessions. A setup that prints on the London open behaves nothing like the same setup in the dead Asian hours. Spreads, pip values and news windows all matter — and a backtest that doesn't respect them isn't telling you the truth about your edge.
Proper backtesting software lets you replay those sessions candle by candle, so you learn when your edge fires, not just whether it exists.
What to test on forex
Start with session behaviour — the classic Asian-range-into-London-expansion, and how price reacts through the London–New York overlap. Test one pair and one setup at a time: EURUSD for clean, liquid structure, GBPUSD for volatility, USDJPY for trend and the JPY pip quirk.
And size every test correctly. A pip is 0.0001 (0.01 on JPY pairs), and the right position depends on your stop distance — the position size calculator handles the pip math so your backtest reflects real risk.
