Insider Trading Tracker FAQ

What is insider trading?

In this context, we're referring to legal insider trading — when company officers, directors, and large shareholders buy or sell their own company's stock. They're required to report these transactions to the SEC via Form 4 filings. This is completely legal and public information. We do NOT track or encourage illegal insider trading based on material non-public information.

How is this different from OpenInsider?

We filter out the noise by default. 80% of Form 4 filings are routine option exercises and compensation grants that mean nothing. We show only open market purchases — the trades where insiders put their own money on the line. Plus we offer smart alerts, AI context, and a modern mobile-friendly UI.

How often is the data updated?

Our EDGAR poller runs every 30 minutes, pulling the latest Form 4 filings from the SEC. Data typically appears in our system within an hour of being filed with the SEC.

Is this data legal to use?

Absolutely. All Form 4 filings are public records available through the SEC's EDGAR system. Anyone can access this data. We simply make it easier to find and filter the filings that matter.

What is a Form 4 filing?

Form 4 is a document filed with the SEC whenever a company insider (officer, director, or 10%+ shareholder) buys or sells their company's stock. It must be filed within two business days of the transaction.

What Is an Insider Trading Tracker and How Does It Work?

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.
