Made for index and futures-style traders

Real index history

Years of genuine US30, US100 and SP500 price data from 1-minute to monthly candles, with custom timeframes for your exact style.

Session tools for NY killzones

Session boxes and timezone-aware charts help you isolate the New York open, London session or any killzone your strategy needs.

Realistic order simulation

Entries, stops and targets fill with gap awareness — critical on indices, where opening gaps punish naive backtests.

Prop-firm challenge mode

Trade your replay under FTMO-style rules: profit target, daily loss limit, max drawdown and consistency — see if you would pass before paying for a real challenge.

Journal and stats

Automatic trade logging with win rate, R-multiples, drawdown and per-setup breakdowns.

Frequently asked questions

Is index backtesting free here?

Yes — US30, US100 and SP500 replay, orders, journal and challenge mode are all free. The project is community-supported.

Can I practice prop-firm challenges on indices?

Yes. Enable challenge mode and set profit target, daily loss and max drawdown rules (FTMO-style defaults included), then trade the replay under those constraints.

Do the charts handle sessions and timezones?

Yes — you can set the chart timezone per session and draw session boxes, which matters for NY-open and killzone strategies on indices.

Is this a free alternative to paid index replay tools?

Yes: web-based bar replay for indices with realistic order simulation, at no cost. See our comparison pages for details.
