01. Source ingestion
The production worker monitors covered issuers for SEC Form 4 and 4/A filings on a recurring schedule, preserving accession numbers and filing timestamps where available.
Public filings // documented transformations
FROM EDGAR FILING
TO AUDITABLE RESEARCH DATA.
InsiderAlpha turns public ownership filings into a searchable research layer while keeping source lineage, quality state and derived methodology visible. The goal is not to manufacture a trading prediction; it is to make the underlying evidence easier to inspect and analyze.
02. Canonical identity
Canonical transactions are identified by accession number, SEC transaction table and sequence. Amendments and overlapping historical representations are tracked explicitly.
03. Quality states
Deterministic validation rules assign quality, eligibility and source-verification states. Missing values remain visible; ambiguous records are not silently promoted.

Release changelog
Current public release: schema 2.0.0, generated from the documented commercial package with checksum and row-count integrity records.
Research use only
InsiderAlpha publishes normalized public-filing data and descriptive research fields. It does not provide investment advice, trading recommendations or return promises.
Evidence over certainty
Institutional presentation starts with disclosed limitations.
SEC filings are issuer- and owner-reported public records. They may contain amendments, footnotes, zero-price technical events, delayed submissions and corporate-action edge cases. InsiderAlpha normalizes and enriches those records, but does not claim perfect source data or causal investment signals.
