Test a strategy. Then let it run for you.

Choose it, test it, let it run

Your money stays in your own brokerage account. Tactfolio never holds it and never takes a cut of your trades.

1. 1 Choose

   Pick a strategy

   Start from one of 63 strategies from books and research papers, a strategy another member shared, or your own idea in plain blocks.

   Browse the strategies →
2. 2 Test

   See how it held up

   Every backtest runs on real daily prices next to simply holding the market. You see its growth, its worst drop and its bad years.

   What a backtest can’t tell you →
3. 3 Run

   Let it run for you

   Plus runs it every market day. Follow up to 25 strategies on paper and get an email of what each one holds and trades, or let one place its trades in your own Alpaca account.

Check our work, not our word

The Tactfolio Research Lab, the team behind Tactfolio, shows its sources, its assumptions and its numbers.

  classic strategies, each linked to where it was published, with every place our version differs written down.

  Read one →
• 107

  sources cited and linked, so you can read each rule where it came from.

  See an example →
• Every close

  charts and tables are recomputed on prices adjusted for splits and dividends, with a cost on every trade.

  Our methodology →
• Out of sample

  every published strategy marks the day its rules were fixed, so its live record is kept apart from its backtest.
