InsiderTradingRadar watches SEC EDGAR for Form 4 insider filings and alerts you within minutes of a filing. Every trade is classified across 20 SEC transaction codes, so open-market purchases stand apart from option exercises, gifts and tax withholding. Pre-scheduled 10b5-1 sales and mechanical noise are filtered out, and every alert shows how that insider's past trades performed. Cluster detection flags when several insiders at the same company buy together.
