From SEC filing to your inbox, in under a minute.
Watch4Insider monitors every Form 4 the SEC publishes and emails you only the ones that match your rules. Here's the entire pipeline, end to end.
The four steps in detail
Build a screener
Pick the trades you care about. Screeners are queries — not ticker subscriptions — so they keep working as new companies file.
- →Transaction type (open-market buys, sales, gifts, exercises…)
- →Insider role (officer, director, 10% owner, other)
- →Dollar value range and share count
- →Time window — last N days of filings
Save it as an alert
Name the alert, add the destination email addresses, and switch it on. Each plan caps how many alerts and how many recipients per alert.
- →Basic: 5 alerts, 1 email per alert
- →Premium: 25 alerts, up to 5 emails per alert
- →Pause or delete an alert anytime from /alerts
We watch the SEC
A dedicated worker polls SEC EDGAR every few seconds and ingests every new Form 4. Each filing is parsed in memory and matched against every active alert across all users.
- →Form 4 covers 93% of all insider transactions
- →Matching runs in milliseconds — no queue backlog
- →We track the cursor so no filing is missed or duplicated
You get the email
On a match, a plain-text summary lands in your inbox: issuer, insider, transaction code, shares, price, and value — plus a direct link to the SEC filing for the full detail.
- →95% of alerts delivered under a minute from filing
- →Each rule fires once per matching transaction
- →Cancel any time; no contract
