Best Backtesting Software in 2026: 9 Tools Compared
We sell backtesting software, so read this knowing that. Nine tools compared by market, coding, data and dated prices, plus who should skip ours.
Every "best backtesting software" list is written by someone selling backtesting software. This one is too. We built TestMax, so it's on the list, and you should read everything below knowing that.
Here's what we can offer instead of a neutral opinion: prices taken from each company's own page, the month we checked them, and a plain statement of who shouldn't use our product. If you trade stocks or options, skip our entry. We don't cover those markets.
The short answer: the best tool depends on two questions. Do you write code? What market do you trade?
| You are | Start with |
|---|---|
| A futures trader who won't code | TestMax or NinjaTrader's replay |
| A futures trader who codes | NinjaTrader or QuantConnect |
| A forex trader who won't code | FX Replay or Forex Tester Online |
| A forex trader running robots | MetaTrader 5 |
| A chart-first trader on any market | TradingView |
| A stock trader who wants no-code tests | TrendSpider |
| Someone who wants a journal first | TradeZella |

What backtesting software really does
Backtesting software shows you how a set of rules would have behaved on past prices. That's all. It doesn't prove a strategy works, and we have numbers on that below.
The tools split into two families:
- Replay tools hide future candles and let you trade by hand, one bar at a time.
- Automated testers run your written rules across years of data in seconds.
Neither is better. If your rules need judgment, code can't test them. If your rules are exact, doing them by hand is slow. Our how-to guide walks through the steps either way.
The tools, one by one
TradingView
TradingView is the chart most traders already have open. Bar Replay is good, and the Pine Script strategy tester turns a script into a performance report.
The limit is intraday replay. The free plan caps you at 5,000 bars and 2 indicators per chart, and its replay runs on daily charts and up. Minute data in replay starts on Essential ($12.95 a month billed yearly) with 180 days, per its pricing page.
Best for: traders who already live on TradingView and test swing ideas. Skip it if: you want years of 1-minute futures replay on a small budget.
NinjaTrader
NinjaTrader says its platform is free for charting and strategy backtesting, with no time limit. Strategy work means NinjaScript, and the software is a desktop install. Market Replay asks for a deposit in a NinjaTrader brokerage account, per its pricing page. Paid plans are $99 a month or $1,499 once, and those mostly lower commissions.
Best for: futures traders who code and may trade through NinjaTrader. Skip it if: you don't want to install software or learn NinjaScript.
MetaTrader 5
MT5's Strategy Tester has been the default for forex robots for years. It offers three test modes: every tick, 1-minute OHLC and open prices only. It also supports forward testing, which helps catch over-fitted settings.
The catch is that you test robots written in MQL5. Manual traders get far less from it.
Best for: forex traders running automated systems. Skip it if: you trade by hand or want a clean browser tool.
QuantConnect
QuantConnect is the serious option for programmers. You write Python or C#, and its free plan lists unlimited backtesting on one node across equities, indexes, forex, crypto, futures and options.
The price of that power is that you need to be comfortable writing and debugging code.
Best for: developers and quants. Skip it if: you don't code. There's no way around it.
FX Replay
FX Replay is a clean browser replay tool, and it's a real competitor of ours. The free Beginner plan gives you 2 sessions, 1 indicator and 1 week of data retention. Intermediate is $17.99 a month or $180 a year. Futures data needs Pro at $35 a month or $350 a year, per its pricing page.
Best for: forex traders who want simple replay. Skip it if: you need futures on a small budget.
Forex Tester
Forex Tester has been around for a long time, and Forex Tester Online brings it to the browser. It offers a free demo with no card. Forextester.com pages listed yearly plans from $159 to $299 in early November, some of them on promotion. Read the live price before you buy.
Best for: forex traders who want a mature manual tester. Skip it if: you want a lasting free plan.
TradeZella
TradeZella is a trading journal first, and backtesting lives inside it. All plans include bar-by-bar testing with 11+ years of data. Prices are $35, $59 and $99 a month, or $26, $44 and $74 billed yearly. We saw no free plan on that page.
Best for: traders who want their journal and backtests in one place. Skip it if: you only want to backtest and don't need the journal.
TrendSpider
TrendSpider tests rules with no code, and it covers stocks well. Testing depth depends on the plan: Standard tests at 2-hour bars, Premium at 5-minute, and Enhanced and Advanced at 1-minute. The 14-day trial costs $19, and futures data costs extra, per its pricing page.
The published prices ran on a Halloween promotion when we checked, so the numbers may have moved.
Best for: stock traders who want automated tests without code. Skip it if: you want cheap intraday testing, since that depth sits on the upper plans.
TestMax
This is ours. TestMax replays real historical market data in your browser, candle by candle, with simulated orders and a trade log. You can also write Python strategies in the Algo Playground on Pro.
The Free plan covers the latest 2 months of data on NQ, ES and other Free-enabled instruments, on a single chart with ads. Pro is $14.99 a month or $143.90 a year, and adds full history, MNQ, MES, GC, multi-chart layouts and Challenge Mode.
Now the part most vendor lists leave out:
- We don't have stocks or options.
- We don't offer CL futures.
- Orders fill against the bars of your chart timeframe. We don't simulate an order book.
- Replay doesn't charge commissions or slippage. You need to subtract them yourself.
- The chart needs a tablet or computer. A phone won't do.
Best for: NQ and ES traders who want hand-traded replay with no install. Skip it if: you trade stocks or options, or you need order book simulation.
What to check before you pay
Does it cover your exact market? "Futures" on a feature list can mean a paid add-on or a higher tier. Check the symbol you trade.
How far back on your timeframe? Ten years of daily bars won't help a scalper. Ask how much 1-minute history you get.
How does it decide your fill? This one matters more than people think. We ran a 16-year NQ test and changed only the assumed entry price. Filling at the next candle's open gave a small loss. Filling at the breakout line gave a large profit. Same rules, same data. Our cost worksheet covers the fees and slippage side of the same problem.
Can you hide the future? If the tool shows the full chart, you'll see the outcome before you decide. A replay mode fixes that.
What's the real yearly cost? Add data fees, add-ons and the plan you'd need for your timeframe. The entry price is rarely the price you'd pay.
Common questions
Is there free backtesting software? Yes. NinjaTrader, QuantConnect, MetaTrader 5, TradingView, FX Replay and TestMax all have a free way in. Each one has a catch: code, an install or a short history.
Is backtesting software worth paying for? Only once a free plan stops you. If you can't reach 100 trades of one setup, a paid plan is worth a look. If you haven't tried yet, more data won't help.
Can I backtest without coding? Yes. TradingView Bar Replay, FX Replay, Forex Tester, TradeZella, TrendSpider and TestMax replay all work with no code.
Does a good backtest mean a strategy will work? No. It means the rules survived one look at the past. In our 16-year NQ test, 2024 and 2025 were both strong years, on rules that lost money overall.
Which one would we pick?
If you trade NQ or ES and don't code, start with our Free plan. We'd say that, but it costs nothing to check, and you'll know in one session whether it suits you. Our free NQ walkthrough shows one full session.
If you code, QuantConnect or NinjaTrader will take you further than we will on pure automation. If you trade forex by hand, try FX Replay's free plan next to ours. If you want a free tool for daily charts, TradingView is fine and you probably have it already.
Try two tools on the same day of data, with the same rules. Compare what each one gave you. That one hour will teach you more than any list, including this one.
