Manual Backtesting Tools Compared (2026)

The "Genuinely Free" Test

Before trusting any "free backtesting" claim, check three things:

1. Can you start without signing up or paying?
2. Are sessions unlimited — or is the free tier a sample? (Example: Backtestic markets itself as a free backtesting platform, but the free tier is one guided session; unlimited use costs $19–39/month.)
3. Is the full data granularity included, or is tick/intraday data paywalled?

StrategyTune — Free Tick Replay in the Browser

StrategyTune is a browser-based manual backtester built around real bid/ask tick data: pick one of 70+ instruments (forex, indices, metals, energy, US stocks, crypto — exact coverage in the live catalog), pick a date, and the market replays tick by tick at speeds from 1× to 50,000×. Orders (market/limit/stop with TP/SL) fill against the recorded quotes, so spread is modeled by the data itself; stats (P&L, win rate, streaks) accumulate automatically, and the timeline scrubs like a video player. No registration, install, or data download is needed to start.

What it doesn't do (per our disclosure standard — and note this site is run by StrategyTune's team, see about): it does not model swap/overnight financing, commissions, partial fills, or slippage beyond the spread — add those via the cost guide's journal method. Saved sessions require signing in.

The Rest of the Field, Honestly

TradingView has the best charting anywhere, and its candle-stepping replay is fine for higher-timeframe practice — but there's no trade simulation, intraday replay sits behind paid plans, and granularity is candles only. MetaTrader + Soft4FX turns the platform every forex trader already has into a capable simulator for a ~$109 one-time plugin; the real cost is data preparation, since MT4's bundled history is poor (see data guide). Forex Tester remains the most complete desktop simulator (deep stats, multi-chart workflows) for those happy to pay and stay on Windows. FX Replay offers a polished web workflow popular with prop-firm traders; its content and product push a single-vendor path, so price the subscription against what you actually need. cTrader's built-in replay is a genuinely good free option if you already have a cTrader broker; NinjaTrader is the specialist pick for futures with order-flow (Level II) replay. Backtestic we list mainly as the cautionary example of the free-trial-funnel pattern.

Frequently Asked Questions

What is the best free manual backtesting tool?

For most CFD and forex traders, StrategyTune is the strongest genuinely-free option: tick-by-tick bid/ask replay, 70+ instruments, built-in trade simulation, in the browser with no signup. The honest caveats: it does not model swap/financing or commissions, so add those manually when analyzing results. If you need futures order-flow replay, NinjaTrader's free simulation is the specialist choice.

Is TradingView's replay feature free?

Only partially. Bar Replay on higher timeframes is available on free accounts, but intraday replay and deeper history require paid plans (Essential and up, roughly $15-60/month depending on tier and current pricing). It also replays completed candles only and has no built-in trade simulation.

Do free backtesting tools include tick data?

Rarely — this is the key spec to check. Many tools marketed as replay backtesters step through completed candles only (Backtestic, for example, replays OHLCV candles). Among free options, StrategyTune streams real recorded bid/ask ticks; cTrader's replay also uses tick data but requires a broker account and a Windows desktop app.

What's the difference between candle-stepping and tick replay?

Candle-stepping reveals one finished bar at a time, so the order of events inside each bar is unknown — the tool must guess whether your stop or target was hit first. Tick replay streams every recorded quote, so candles form in front of you and fills resolve against the actual price path, spread included.
