Read the disclosure, then the context

Insider data covers the trailing 12 months on public tables. Congressional tables cover all saved disclosures. Neither is an exhaustive history. Form 4 filing dates and congressional disclosure dates may differ from trade dates. Congressional amounts are ranges, not estimated dollar totals. Disclosure activity alone does not establish intent or predict returns.
