“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 free plan, 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 free-tier 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 tiers with hard caps: FX Replay’s Beginner plan and Secuora’s free plan are this — no card, no expiry, limits by design. 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, for example, requires payment details and converts after five days unless cancelled (per its own support docs, June 2026). 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’s free plan — crypto replay plus a real journal
Ours, so check the claims against the live product — there is a demo at /backtest/demo that requires no sign-up at all, which is the fastest way to verify. The free plan needs no card and includes bar-by-bar 1-minute replay: 2 sessions, each covering up to 10 days of market time and 50 trades, on a 90-day crypto history window — and sessions never expire, so a replay you start in June is still there in December. It also includes a 20-trade journal with emotions, rules, screenshots and a P&L calendar, two indicators, and drawing tools.
The honest limits: 2 sessions with 10 market-days and 50 trades each; replay covers crypto (90-day window) plus a short 14-day window on five FX majors (EUR/USD, GBP/USD, USD/JPY, USD/CHF, gold) — full forex depth, stocks, indices, metals and futures (including NQ/ES) need Pro at $29/month or $23/month billed yearly — the journal caps at 20 trades, and two indicators is two indicators. There is also 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 free — 2 replay sessions (10 market-days, 50 trades each) on crypto plus five FX majors, never-expiring sessions, 20-trade journal, 2 indicators, drawing tools, no card; demo needs no account (as of June 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) and Secuora’s free plan (2 replay sessions of 10 market-days/50 trades each on crypto plus five FX majors, 20-trade journal, 2 indicators) both require no card, and Secuora’s sessions never expire — verified June 2026. 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.
