Insider Trading Tracker monitors SEC EDGAR for Form 4 filings in real time and filters out the 80% of noise — routine option exercises, RSU vestings, and pre-planned sales. You see only open market purchases, where insiders spend their own cash to buy shares of their own company. Filter by market cap, sector, insider role, and trade size. Set email alerts, build watchlists, and use AI-powered context to understand why a trade stands out. Includes cluster buying detection to spot when multiple insiders at the same company are buying. Built for retail investors, traders, and analysts who want clean signal without the OpenInsider noise. Free tier available.
