“Are there any free tools for backtesting, or do they all cost money?” is one of the most common questions new traders ask, and it usually gets answered with affiliate links to paid tools. The honest answer is that a few genuinely free options exist, each with sharp edges in a different place: caps on sessions, caps on retention, caps on markets, or simply a cost paid in your hours instead of your dollars.
This guide compares the realistic free options: TradingView’s built-in bar replay, FX Replay’s free tier, Secuora’s no-signup demo, and the $0 classic of a spreadsheet plus manual chart scrolling. Every cap quoted was verified in June 2026. Disclosure: Secuora is our product, and its limits are listed just as bluntly as everyone else’s.
Three kinds of “free”: read the fine print
Before comparing tools, separate three things that all get marketed as free. First, forever-free options with hard caps: FX Replay’s Beginner plan is this (no card, no expiry, limits by design), and so is Secuora’s live demo (no account at all, watch-and-study replay). Second, trials wearing a free costume: anything that takes your card and auto-converts is a purchase with a countdown, not a free tool. FX Replay’s paid-plan trial requires payment details and converts after five days unless cancelled (per its own support docs, June 2026), and Secuora’s own 3-day trial works the same way: card up front, auto-converts unless you cancel. If it needs your card, it is not a free tool; it is a calendar reminder to cancel.
Third, free-with-your-time: a spreadsheet and a chart cost nothing and cap nothing, but every hour of clerical work is the price. All three kinds can be the right answer; they are just not the same answer.
TradingView’s bar replay: fastest to start, thinnest to practise
If you already chart on TradingView, its built-in bar replay is the lowest-friction way to step a chart back in time: pick a date, hide the future, advance candle by candle. For quickly eyeballing how a setup looked across a few weeks of history, nothing beats a tool you already have open.
Its limits are about what it is, not bugs: it is a charting feature, not a practice environment. The order-simulation, session-statistics and journaling layer around replay is thin, and how far back you can replay (and on which timeframes) depends on your TradingView plan tier. It is great for asking “how did this setup look in March?” and thin for answering “am I actually profitable trading it?” For idea triage, start here; for deliberate practice, you will outgrow it.
FX Replay’s free Beginner tier: real workflow, one-week memory
FX Replay’s Beginner plan is genuinely free forever, with no card required, and it gives you the real product workflow: TradingView-powered charting, bar-by-bar replay with simulated orders, and the built-in journal. The verified caps as of June 2026:
- 2 backtesting sessions at a time
- 50 trades per session
- 1 indicator
- 1-month maximum session duration
- 1-week data retention
What those FX Replay caps mean in practice
Two sessions and 50 trades per session is enough to feel the workflow and run a small experiment. The cap that bites first is retention: your session data lives one week, so the longitudinal record (the growing sample that backtesting is supposed to build) evaporates unless you upgrade or export your conclusions elsewhere. One indicator also constrains most rule sets beyond pure price action.
Upgrades run $17.99/month (Intermediate) or $35/month (Pro) as of June 2026, with futures/CME data and seconds-level resolution sitting on Pro only. As a free tool, it is a high-quality taster deliberately sized to stay a taster.
Secuora: a no-signup demo, and a trial that takes a card
Ours, so check the claims against the live product: the genuinely free part is the demo at /backtest/demo, which requires no sign-up at all. It runs the real replay chart in your browser: pick a date, hide the future, step real historical price forward bar by bar. It is watch-and-study rather than full practice; the order ticket, session saving and journaling live in the full product.
The full product is covered by a 3-day free trial on every new account, and it deserves the same fine print as everyone else: it takes a card and auto-converts unless you cancel, so by this guide’s own definition it is a purchase with a countdown, not a free tool. During the trial everything except the AI backtester works: every market (crypto, forex, stocks, indices, metals and futures including NQ/ES), replay sessions with simulated orders, the journal, indicators and drawing tools. Pro afterwards is $29/month or $23/month billed yearly, and there is no broker auto-import on any plan. One more free thing worth taking even if you never sign up: our published backtest research at /strategy, 12 months of BTC/ETH with fees on, where every unfiltered mechanical baseline we tested lost money after costs. The numbers are not flattering, which is rather the point.
The $0 classic: a spreadsheet and manual chart scrolling
The original free backtesting stack: scroll a chart back in time keeping the future off-screen, mark your hypothetical entries and exits, and log each one in a spreadsheet with hand-built win-rate and expectancy formulas. It is truly unlimited and truly free, and building the formulas yourself teaches the metrics better than any dashboard.
The failure modes are equally real. Manual scrolling makes peeking free, and peeking quietly corrupts every number you produce, because you can never fully unsee the right edge of the chart. Sample-building is slow, order fills are honor-system, and the statistics only update if you maintain them. It works, and traders have used it for decades; just price in the hours and the discipline it demands.
Side by side
- TradingView replay: fastest start if you already chart there; a review tool more than a practice environment; replay depth tied to your plan tier.
- FX Replay free: real replay workflow with simulated orders; 2 sessions, 50 trades/session, 1 indicator, results retained one week (as of June 2026).
- Secuora: the demo needs no account and steps real history bar by bar (watch-and-study); the full product is a 3-day card-required trial, then $29/month or $23/month billed yearly (as of July 2026).
- Spreadsheet + scrolling: unlimited and $0; you pay in hours, look-ahead risk and hand-maintained stats.
When free is enough, and the honest upgrade triggers
A free tier has one job: prove that you will actually do the work. The habit, not the tool, is the usual bottleneck (plenty of paid backtesting subscriptions go unused after the first few weeks) so collect your first 50–100 replay trades on a free tier before paying anyone. Free is also exactly the right place to learn the most valuable lesson in backtesting: raw, unfiltered entries rarely survive costs (our own published research found none of the mechanical baselines we tested did), so the work is discovering which of your filters earns its keep.
Upgrade when a cap is blocking your learning, not because a sales page says serious traders pay. The honest triggers:
- Your market is not covered free: futures, forex or stocks rather than crypto.
- Retention or session caps keep deleting the sample you are trying to build.
- Your strategy genuinely needs more indicators or longer continuous sessions.
- You are spending more time maintaining spreadsheets than reviewing trades.
Frequently asked questions
Is there completely free backtesting software with no credit card?
Yes. FX Replay’s Beginner plan (2 sessions, 50 trades/session, 1 indicator, 1-week retention) requires no card, verified June 2026. Secuora’s demo at /backtest/demo needs no account at all: it is watch-and-study bar replay, while the full product runs on a 3-day trial that takes a card. TradingView’s bar replay is also included with its plans.
What are the limits of FX Replay’s free plan?
As of June 2026: 2 backtesting sessions, 50 trades per session, 1 indicator, a 1-month maximum session duration, and 1-week data retention, and no futures data (futures/CME requires the $35/month Pro plan).
Can I try backtesting without creating an account?
Yes. Secuora’s live demo at /backtest/demo runs the replay terminal in the browser with no sign-up and no card. It is the fastest way to find out whether bar-by-bar practice suits you before committing to anything, free or paid.
Is free backtesting accurate enough to trust?
The tool matters less than the method: hide the future, fix your risk, include costs, and take enough trades. A free tier run honestly beats a paid tool run with peeking and no commissions. The caps on free plans limit how much you can test, not how honest the test is.
