Try your strategy

Pick a rule from the catalog, adjust its parameters and symbols, and in minutes you get a backtest over ten years of daily data: facts with their trade counts, robustness, and an estimate of how long the gate would take in paper. No account or card.

  • Facts, not a verdict. Net result, average per trade, maximum drawdown and concentration, each with its trade count.
  • "It can't be known yet" when that is the case. With fewer trades than the sample of its horizon there are no percentages and no money verdict.
  • Robustness. Trade reshuffle, a map of neighboring parameters, and the result by year against SPY and by symbol.
  • A private link. The report lives at an address with your code; whoever has it can see it. You can delete it whenever you want.

It is a backtest with historical data and assumed costs: it does not predict future results, recommend what to trade or give signals. The real gate is measured with trades in paper.

Set up the backtest

Up to 12 tickers separated by commas, for example SPY, QQQ. US stocks and ETFs with history loaded only.

Only so that you can ask us to delete your data. Without an email everything works the same with the report link.

Backtest over 10 years of Alpaca daily data, with 5 bp of slippage per trade and no commission; the report states whether prices are adjusted for dividends. These are facts, not a verdict: with fewer trades than the sample there are no percentages.

What we do with your data

  • We store the template, parameters and symbols you chose to generate the report and so you can see it again with the link. Your email and the irreversible summary of your IP are deleted after 7 days; the report, after 30.
  • We do not ask for broker keys or access to any account: the backtest uses our own historical prices.
  • You can delete everything at once with the "Delete my data" button on the result page, or by writing to [email protected]. More detail in privacy.
  • Already trading and have a history? The free CSV audit measures real trades instead of simulated ones.
