Insider Trading Tracker — See What Insiders Are Actually Buying

An insider trading tracker is a tool that monitors SEC EDGAR for Form 4 filings — the documents that corporate insiders are legally required to file whenever they buy or sell shares of their own company. Insiders include officers (CEOs, CFOs, COOs), directors, and any shareholder who owns more than 10% of a company's stock. Because insiders have deep knowledge of their company's operations and outlook, their open market purchases are often viewed as a strong bullish signal by investors and analysts.

The challenge is that most Form 4 filings are noise. The majority of insider transactions are routine stock option exercises, restricted stock unit (RSU) vestings, and pre-planned sales under 10b5-1 trading plans — none of which reflect a genuine conviction about the company's future. A good insider trading tracker separates signal from noise by filtering for open market purchases only: transactions where insiders spend their own cash to buy shares on the open market at prevailing prices.

Our tracker pulls insider trading data directly from SEC EDGAR's EFTS system every 30 minutes. We parse each Form 4 XML filing and extract only transactions with a transaction code of “P” (open market purchase). You can then filter by trade size, market cap, sector, and insider role to find the signals that match your investment thesis. Features like cluster buying detection — spotting when multiple insiders at the same company are buying within a short window — add another layer of insight. Whether you're researching insider buying trends, tracking specific executives, or looking for conviction signals in small-cap stocks, our insider trading tracker gives you clean, actionable data without the noise.
