The four steps in detail

Step 1
You · 30 seconds

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
Step 2
You · 10 seconds

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
Step 3
Us · runs continuously

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
Step 4
Us · within seconds

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
