SEC Form 4 Insider Transaction Data

Hedge-fund and equity-research analysts get every SEC Form 4 transaction line already pulled out of the filing's own XML, with shares, price and code, not just the fact a filing exists.

Pick a window and get one row for every insider stock transaction line SEC Form 4 filings reported in it: who traded, at what company, how many shares, at what price, bought or sold, and under which SEC transaction code.

Introduction

Every officer, director, and 10%-or-more owner of a US public company has to report a change in their own holding within two business days, on SEC Form 4. Because that filing is made by an insider trading their own company's stock, it is one of the oldest and most widely watched signals in public markets: several officers buying in the open market with their own money in the same week is a different fact than one officer receiving a routine stock grant.

The filing itself is a structured XML document naming the company, the insider, their role, and a table of transactions. EDGAR's own search index lists which filings exist, but not what is inside them — no share count, no price, no code. This Actor lists Form 4 filings for your window from SEC EDGAR's public full-text search API, then opens each filing's own XML document and reads the transaction table out of it, live, on every run.

Tutorial

1. Set Days back to how many days of filings to search, from 1 to 30.
2. Set Maximum rows to your spend cap. Every row bills, so this is also the most a single run can cost.
3. Optionally set Stock symbol (e.g. AAPL) to restrict to one company's insiders, looked up in the SEC's own published company/ticker list.
4. Leave Include derivative-security transactions on for everything (options, RSUs, and plan-related lines included), or turn it off for ordinary-stock transaction lines only.
5. Optionally set Transaction codes to only the SEC codes you want, e.g. ["P","S"] for open-market purchases and sales only, skipping grants, gifts, and plan mechanics.
6. Put your own address in Contact email. The SEC asks every automated reader to name a contact in its request headers.
7. Click Start. Results land in the dataset.

Pricing

$0.01 per row. No start fee.

A row here is not just "a filing happened" — it is one priced, dated trade line read out of that filing's own transaction table, which means opening and parsing the underlying XML document, not just its index entry. A run that finds 60 qualifying transaction lines costs $0.24. A run that finds none because the window held only a quiet weekend costs nothing.

Maximum rows is the spend cap: the run cannot cost more than that number multiplied by $0.01, whatever the window holds.

Recommendations

Run daily with Days back set to 2, the same overlap sec-8k-auditor-officer-changes in this same store uses, so a filing that lands late in EDGAR's day is never missed. Set Transaction codes to ["P","S"] to isolate open-market buys and sells — the two codes that most trading and research use actually acts on — and drop the rest.

Limitations

Only what the filing states. No trade is inferred and no price is estimated. A code this Actor does not carry a plain-English label for is still returned with its raw SEC letter rather than skipped.

A busy window is capped. To keep one run bounded, this Actor opens at most 400 individual filings per run regardless of Maximum rows. A run that hits that cap before reaching your row target says so in its OUTPUT record; narrow the window or add a Stock symbol to cover a busy period fully.

A filing that cannot be opened is skipped, not guessed at. If EDGAR briefly cannot serve one filing's document, that filing is left out and noted in OUTPUT.warnings; every other row in the run is unaffected.

FAQ

Where does the data come from? SEC EDGAR: the full-text search API at efts.sec.gov lists the filings, and each filing's own XML document at www.sec.gov/Archives/edgar/data supplies the transaction table. Both are documented at the SEC's own "Accessing EDGAR Data" developer page, which states scripted access is allowed.

Does it need an API key or a login? No. The only thing the SEC asks for is a contact address in the request, which is the Contact email input.

Why did I get fewer rows than Maximum rows? Either the window held that many transactions and no more, or this Actor's 400-filing safety cap was hit first — check OUTPUT.warnings.

What happens if EDGAR is down? The run pushes no rows, costs nothing, and writes a status of UNKNOWN with the error to OUTPUT. It never fills the gap with made-up rows.

Is there support? Issues can be raised through the Apify Store issues tab for this actor. No response time is promised.
