AlphaAssay is a signal validation and overfitting forensics platform that statistically audits trading signals, backtests, and strategies — returning deterministic pass/fail verdicts with signed, replayable audit records.

Free tools

• assay_demo — Run a free demo to see the full output schema and known-verdict specimens.

• assay_graveyard — Look up anonymised falsification statistics for a signal family before investing time in an idea.

• assay_calibration — View AlphaAssay's own signed public calibration and verdict hit-rate.

• assay_certificate_verify — Offline Ed25519 signature verification of a signed verdict certificate.

• assay_provider_protocol — Get a machine-readable 7-test falsification checklist to audit any signal provider.

• assay_preflight — Lint a payload (DSL schema, OHLCV data, trade rows) before spending a paid check.

Signal & backtest validation

• assay_signal — Validate a trading strategy export with deflated Sharpe, multiple-testing correction, overfitting detection, look-ahead checks, and cost stress.

• assay_backtest — Run a deterministic DSL backtest with honest family-level trial accounting.

• assay_gauntlet — Full reality-check battery: validator, family deflation, placebo, capacity ceiling, and graveyard prior in one call.

• assay_falsify — Actively stress-test a signal with adversarial attacks (execution lag, cost stress, time jackknife, regime split, parameter perturbation).

Overfitting & forensics

• assay_forensics — Diagnose look-ahead leakage, front-loading, random timing comparison, and event independence.

• assay_pbo — Compute Probability of Backtest Overfitting (CSCV) over a full parameter payoff matrix.

• assay_survivors — Apply Romano-Wolf stepwise FWER control to disclose which variants survive family-wise error budgeting.

• assay_batch — Submit up to 25 parameter sweep variants in one call with cumulative deflation applied.

Reproducibility & pre-registration

• assay_reproduce — Independently recompute a claimed track record from trades + candles, grading metrics against disclosed tolerances.

• assay_register — Pre-register a hypothesis with a tamper-proof Merkle-anchored timestamp, making the later verdict immune to overfitting.

• assay_verdict — Fetch a post-cutoff verdict for a pre-registered signal, enforcing sealed hypothesis terms.
