Insider Trading Tracker: SEC Form 4 API — Insidewell
Pricing
Pay per event
See which insiders just bought or sold their own stock. SEC Form 4 insider trading tracker and API: open-market trades from EDGAR as clean JSON for your watchlist or the whole market, cluster-buy flags and daily new-trade alerts. Public data, not advice. $0.004 per trade.
US stock tickers to track (e.g. AAPL, TSLA). A purely numeric entry is treated as an SEC CIK (e.g. 320193 for Apple). Leave empty (or enable 'Track whole market' below) to get the latest Form 4 filings for every company instead of a watchlist.
[]If on, pulls the newest Form 4 filings across all US-listed issuers instead of only the tickers above. Good for a general insider-buying feed; use a watchlist instead if you only care about specific stocks.
Upper bound on how many Form 4 filings to download and parse in this run. The prefilled 5 gives a fast, cheap first try; the default when omitted is 200.
Stop after returning this many transactions (newest first); 0 = no limit. Useful to cap cost. In monitor mode, transactions over the cap are returned on the next run.
Only include filings whose transaction date is within this many days of today. Applies to watchlist mode; whole-market mode is naturally limited to the latest filings.
Skip option exercises, grants, gifts and other non-open-market transaction codes, keeping only code P (open-market purchase) and S (open-market sale) — the transactions most investors actually care about.
Drop transactions worth less than this (shares x price). Set to 0 to keep everything.
Mark a transaction as a cluster buy when 2 or more different insiders at the same company bought on the open market within the cluster window below — a signal some investors watch for.
Window used to detect cluster buying at the same company.
Remembers which transactions this watchlist already returned (by SEC accession number + transaction index) and only returns new ones, plus earlier trades that have just become part of a cluster buy (change: "changed"). Unchanged trades are not returned and not charged. The first monitor run returns everything as "new". Ideal for a daily schedule.
