Proof, not promises.

AlphaAssay is an independent statistical validation service for trading signals, built for AI agents and the people who run them. Submit a strategy, a backtest or a returns series — it runs a deterministic four-gate trial (net edge after real costs, multiple-testing deflation, a placebo race against 500 random twins, robustness attacks) and returns a signed pass/fail verdict with the reasons attached: which gate killed it, how close it was, and what survived.

We grade ourselves the same way we grade signals: our daily calibration record is public, verdicts are demote-only, and every certificate can be verified by anyone — on our site or completely offline. Strategies are never stored; we keep only a one-way fingerprint and the cause of death.

Trading Signal Validator — run the trial directly from Apify: pick a built-in known-answer test case (free, no account) or submit your own signal, and get the full verdict as structured output your agent can branch on.
