Backtest like it's live. Pass the evaluation in practice first.

CME futures such as NQ, ES, MNQ, MES, YM, RTY, CL and GC through your own Databento account (continuous contracts, with the roll dates marked); forex pairs, gold, silver, index CFDs and bitcoin through Dukascopy's free data; or any market you have 1-minute candles for as a CSV file.

Forex and CFD data is free and downloads inside the app. Futures data comes from your own Databento account, which charges per download (new Databento accounts get free credit to start); the app shows the price first and keeps everything you download, so you pay for each month only once.

It can read your real trades, but it never places an order. MetaTrader 5 and cTrader connect through the free Replaybook Bridge add-on, which writes your trades to a file on your PC; TopstepX connects with your own API key, which stays on your PC; other brokers work through their trade files. Live charts use prices from one of those accounts, or clearly labelled demo prices: Replaybook doesn't sell market data. In replay, every fill is simulated and the smallest timeframe is 1 minute.

Yes. Without a subscription, the Windows app lets you play the Daily challenge on free forex and index markets, and anyone can look around an example backtest (made-up prices, 30 trades already journaled), also in the browser. No card needed. The 7-day trial unlocks everything else.

Futures data is traded prices: market orders, stop entries, stop losses and manual closes fill your slippage setting worse (1 tick by default); limit orders and targets fill at their price. Forex data is bid prices, so buys fill at the ask (the bid plus your spread). Inside each 1-minute candle, price is assumed to go open → low → high → close on a green candle and open → high → low → close on a red one, so when a stop and a target are in the same minute you always know which fills first. A stop the market gaps past fills at the open.

Yes, with Pro. Pick Prop-firm challenge in the New backtest window and set the rules: profit target, max loss (static or trailing), daily loss, minimum days, consistency, max contracts and more. Or start from a preset that copies a firm's published rules, with the date they were checked and a link to the firm's own page. Time only moves forward, like a real evaluation, and the limits stay on screen. Firms change their rules, so compare with your firm's current rules. Results are simulated and don't guarantee a pass, and Replaybook is not affiliated with any prop firm.

One trading day from the past, the same for everyone that day; a new one starts at 00:00 UTC. The date stays hidden, you trade 07:00 to 16:00 New York with one trade at a time and 1% risk, and there's no going back. At the end you see the real date, your result and your streak. It's free, even without a subscription, one attempt a day, and it doesn't count toward the Replay plan's 3 backtests.

Start a plan and use everything free for 7 days. If you keep it, you're charged the plan price at the end of the trial; the first 100 members on a monthly plan pay $5 for that first month instead. Cancel anytime from your account page.

Yes, anytime, from Account → Manage subscription in the app or the link in your receipt. Switching from Replay to Pro takes effect right away. When you cancel, you keep your plan until the end of the period you paid for.

Nothing is deleted. Your backtests, charts, journal, notes and pictures stay on your PC and still open. The replay stops where you left off until you subscribe again.

No. All payments are final, including unused time, which is why every plan starts with 7 days free. Cancel before the trial ends and you pay nothing. If you were charged by mistake, email us and we'll fix it. See the Refund policy.

A Windows 10 or 11 PC (64-bit). The installer sets Replaybook up for your Windows user, no admin password needed. Until our installer is code-signed, Windows may say "Windows protected your PC" the first time: click More info, then Run anyway.

Replaybook is a Windows app first. A Mac app is planned; tell us if you want it and we'll let you know when it's ready. Until then, the example backtest runs in your browser on a Mac too.

Yes. The app, your data and your journal are on your PC. It checks your subscription online once a day and keeps working for 7 days without internet.

Two, for example a desktop and a laptop. Sign in with the email you paid with and a 6-digit code we email you; there's no password. On a third PC you can sign out one of the other two right there, once every 30 days.

Replaybook updates itself. It downloads a new version in the background and shows Restart to update; your backtest is saved first. Updates are included while your subscription is active.

Yes. In Appearance → Feel, choose Calm to keep the screens still (it also follows your computer's reduce-motion setting), and set sounds to Off, Quiet, Normal or Loud. The Classic look has no animations, and its sounds start off.

No. Replaybook is a practice and journaling tool. Results in replay, in the Daily challenge and in prop-firm challenge mode are simulated and don't guarantee results in live trading or in a real evaluation.
