NinjaTrader vs Zipline Reloaded (2026)
NinjaTrader (free futures-focused desktop platform with c# backtesting and a built-in brokerage) and Zipline Reloaded (maintained open-source fork of quantopian's event-driven python backtesting engine) solve backtesting differently. The table below compares them on verified specs and pricing; full details are in each review.
Side by side
| NinjaTrader | Zipline Reloaded | |
|---|---|---|
| Overall score | 7.7 / 10 | 6.7 / 10 |
| Engine type | event-driven | event-driven |
| Pricing model | freemium | open-source |
| Free tier | Yes | Yes |
| Entry price | $0 | $0 |
| Languages | C# (NinjaScript), no-code (Strategy Builder) | Python (3.9+, wheels through Python 3.13 as of v3.1.1) |
| Asset classes | futures (native brokerage), stocks (data/backtest via third-party feeds), forex (data/backtest via third-party feeds), crypto (data via Coinbase adapter) | US equities, ETFs, futures (continuous futures support), crypto/other via custom bundles and calendars (community workarounds) |
| Bundled data | Free real-time CME market data with a funded brokerage account, free end-of-day data via Kinetick for unfunded users, and historical tick/minute futures data downloadable in-platform. Without a funded account, Level 1/Level 2 CME data costs ~$12/$41 per month. Non-CME exchanges (e.g. Eurex, ICE) cost extra. | No usable current data ships with the library. The default Quandl/WIKI bundle (via NASDAQ Data Link) covers US equities only through March 2018, so you bring your own: either the csvdir bundle, which takes OHLCV CSVs with splits and dividends, or your own custom bundle ingest code. |
