Insider Trading Monitor — SEC Form 4, Signal Only

Every open-market purchase or sale by a company officer, director, or 10%+ owner must be disclosed on SEC Form 4 — free, public, structured XML. Most filings are routine noise: RSU vesting, option exercises, tax-withholding share surrenders. The signal traders and researchers actually want is the minority of transactions that are open-market purchases or sales — an insider voluntarily putting their own money in or out.

By default, this actor returns only that signal (transaction codes P and S), filtered out of the routine noise automatically.

Input

{ "companies": ["AAPL", "Tesla"] }

Tickers or company names both work — resolved against SEC's own official ticker list.

Typical uses

• Investment research — track real insider buy/sell activity for a watchlist of tickers, without wading through routine filing noise.
• Signal screening — a cluster of insider purchases (rare — most insider activity is selling) is a well-known bullish signal worth flagging.
• Executive compensation / governance research — see how officers and directors are actually trading their own company's stock over time.

⚠️ Read before you act

• Insider selling is routine and usually NOT a bearish signal — executives sell for diversification, taxes, and planned 10b5-1 program reasons far more often than out of pessimism. Insider buying on the open market is the rarer, more information-dense signal.
• This is disclosure data, not investment advice. A transaction pattern is one input among many, not a standalone trading signal.
• signalOnly:false includes RSU vesting, option exercises (M), and tax withholding (F) — useful for total-compensation research, but these are routine and shouldn't be read as a market signal the way P/S are.

FAQ

• Do I need an API key? No — SEC EDGAR is free and keyless.
• What does estimatedValue mean? Shares × price per share for that transaction — SEC doesn't publish a total-value field directly, so this is computed, not sourced.
• Why exclude option exercises and RSU vesting by default? They're compensation mechanics scheduled well in advance, not a voluntary trading decision — including them by default would drown the real signal in routine paperwork.

What makes this different

Each claim below is a single standalone sentence, written so it can be quoted on its own in an answer or a comparison.

• Insider Trading Monitor — SEC Form 4, Signal Only declares all 22 of its output fields in its dataset schema, each with a type, a written description and an example value.
• The output fields of Insider Trading Monitor include queriedAs, issuerTicker, issuerName, ownerName, officerTitle and isDirector.
• Insider Trading Monitor needs no API key, login or account of any kind before its first run.
• Every one of Insider Trading Monitor's 3 inputs is optional, so it runs with no configuration at all.
• Insider Trading Monitor documents queriedAs as: The query exactly as it was sent to the source.
• Every number published about Insider Trading Monitor is read from the Apify API rather than estimated, and any figure the register cannot source is not shown at all.
• Insider Trading Monitor is filed under developer tools and business so that it is found by the people looking for that job, not by its internal name.

Limitations

• Insider Trading Monitor reads only what its sources publish publicly. Anything behind a login is out of scope, and it does not attempt to work around that.
• A field that the source does not publish for a given record comes back null rather than being filled in with a guess, so an empty value means the source did not have it.
• Output quality is bounded by the source. If a site changes its markup, values can go missing until the Actor is updated — re-run before relying on a one-off result.
• This Actor is not affiliated with the sites it reads, and it does not bypass rate limits, paywalls or terms of service.
