How It Works

Three steps between SEC filings and your dashboard.

1

We monitor 10,000+ Form 4 filings daily

Our poller checks the SEC EDGAR system every 30 minutes for new Form 4 insider transaction filings.

2

We filter out option exercises and grants

80% of filings are noise — routine compensation. We automatically discard them and keep only what matters.

3

You see only meaningful purchases

Open market buys where insiders spend their own cash. Filtered, sorted, and ready for analysis.

Frequently Asked Questions

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.
