Frequently asked

Is the backtester really free?

Yes. Running a backtest here needs no account, no email, and no card. Every result gets a stable public URL you can share or embed.

Do I need an account?

Not to run or share a backtest. A free account adds saving runs, tweaking strategy parameters, and re-running on fresh data as new candles arrive.

What data does it use?

Real historical exchange price data, replayed bar by bar. The simulation executes the strategy's rules candle by candle — it is a replay of history, not a projection.

What does the robustness score mean?

It estimates how likely the result is a real edge rather than curve-fitting. It combines a deflated Sharpe ratio (corrects for luck and repeated trying) with a white-noise check (could random trading produce this?). A pretty equity curve with a bad robustness score means the strategy memorized the past.

Can I test my own strategy idea?

This page runs published strategies and house presets. To build and test your own rules — visually or in YAML, including TradingView Pine Script import — create a free account in the strategy studio.
