SEC Form 4 Insider Trading, Decoded

Real insider conviction from SEC Form 4 filings. Classifies every transaction by its one-letter code, so an RSU vest is not reported as an insider buy and the automatic tax withholding that follows is not reported as a sale. Returns only codes P and S — the trades where someone chose to move money at the market price — plus cluster-buy detection when several insiders buy the same issuer within a window. Query by ticker or CIK.
