Insider Stock Trader

SEC Form 4, decoded

Insider buys,
minutes after filing.

When a CEO buys their own company's stock with their own money, the world finds out on SEC Form 4. Insider Stock Trader reads every filing the moment it lands and turns it into a clear feed and fast alerts.

The feed

Open-market buys and sales as they're filed, with value, role and filing time. Filter by buys, sales, $1M+, cluster buys and CEO or CFO trades.

Plain English

Each trade in one sentence: who, how much, at what price, and what they hold afterwards, linked to the original filing on SEC.gov.

Signal strength

A simple score for open-market buys: the insider's role, the size of the buy, the change in their stake, and whether other insiders are buying too.

Alerts that matter

CEO and CFO buys, cluster buys, large buys and your watchlist, with quiet hours and a daily digest.

How it works

  1. An insider trades. Officers, directors and 10% owners must report trades in their own company's stock on SEC Form 4, usually within two business days.
  2. SEC publishes the filing. We check EDGAR about every minute while it's open and read each new Form 4 in full.
  3. You see what matters. The trade appears in your feed in plain English, scored and filtered, and you get an alert if it matches your settings.

Questions

Is insider buying legal?

Yes. Officers, directors and 10% owners may trade their company's stock, but must report each trade on SEC Form 4. These filings are public records.

Where does the data come from?

Directly from the SEC's EDGAR system. We don't buy or resell third-party data, and every trade links to its original filing. See the Transparency page.

Can I trade in the app?

No. Insider Stock Trader is an information app: no brokerage, no order routing, no investment advice.

How much does it cost?

A yearly or monthly subscription through Google Play. The price is shown in Google Play before you subscribe, and you can cancel anytime there.

How do I delete my account?

In the app under Settings → Delete account, or by email. Step-by-step guidance is on the account deletion page.
