Form 144 API — Planned Insider Sales Before They Happen

See which executives, directors and major holders plan to sell their stock — the day they file the notice, often before the sale shows up anywhere else.

Before an insider or affiliate sells restricted or control stock, they must file SEC Form 144: a notice of proposed sale. Form 4 tells you about a sale after it happened; Form 144 is the early warning. This Actor turns the raw EDGAR notices into clean rows: who is selling, how many shares, the dollar value, the planned sale date, the broker, and whether the sale runs under a pre-scheduled Rule 10b5-1 plan.

FAQ

Does a Form 144 mean the insider will definitely sell? No. It's a notice of a proposed sale. Most are followed by a sale, but some aren't. Pair it with the Insider Trades Tracker to see the Form 4 that confirms the sale.

Who has to file Form 144? Affiliates of the company (officers, directors, large holders) and anyone selling restricted stock, when they plan to sell more than 5,000 shares or $50,000 in any 3-month period.

What is a 10b5-1 plan? A pre-arranged trading plan adopted in advance, often months earlier. Plan sales are usually routine. Sales without a plan are discretionary, so set planFilter to noPlan to see only those.

How far back does the data go? Form 144 became electronic on EDGAR in April 2023. Earlier notices were filed on paper and aren't available as data; they're skipped and counted in SUMMARY.nonXmlFilingsSkipped.

Why is ticker empty for some rows? A few issuers (e.g. delisted or non-US-listed companies) have no ticker in the SEC's list. Issuer name and CIK are always present.

Is this legal to use? Yes. Form 144 notices are public filings published by the US Securities and Exchange Commission.
