How it worksRun a test

Strategy Builder

Build a strategy with no code — pick indicators and conditions, backtest it honestly (costs on, no look-ahead, measured against buy & hold), then forward-test it on paper. Use the Form view for speed or the Canvas to drag blocks together — both build the same strategy. Building one is the easy part; the honest question is whether it actually beats buy & hold — most don't, and this is how you find the rare one that does.

Launch beta. The paid features — forward-testing, alerts, and the advanced-risk tools — are free for everyone right now, with generous limits. When the beta ends, anything you've set up is kept, but you'll need a plan to keep those running. I'll give you notice first.

This is the custom door — compose your own entry and exit rules. Just want to test a well-known strategy on a famous asset instead? Run a backtest →

Same engine, every mode — the verdict and reality-check never change; simpler views just show fewer panels.

Tweaking parameters until the curve looks great is overfitting — it rarely survives live. The honest test is out-of-sample: once it looks good, forward-test it on paper before trusting it with real money on your own broker.
