Insider Trading History — Form 4 SEC Filings Tracker — Probabli.AI
Look up years of Form 4 SEC insider trading filings for any publicly traded company. Track open-market buys, sells, and awards by executives and directors — with cluster buy signal detection.
The Insider Trading History tool lets you look up years of Form 4 SEC filings for any publicly traded company. See every open-market buy, sell, and award reported by executives, directors, and other corporate insiders — visualized as a monthly bar chart alongside a filterable transaction table. Cluster buy signals highlight when three or more insiders purchase shares on the open market within a 14-day window, a historically bullish pattern.

Enter a ticker symbol and click 'Analyze.' The tool fetches up to several years of Form 4 data directly from SEC EDGAR. Use the date-range buttons (1Y / 2Y / 3Y / All) to zoom the chart and filter the table. Use the type filter to focus on open-market buys, sells, or stock awards.

Frequently Asked Questions
What is a Form 4 and why does it matter?
Form 4 is an SEC-required disclosure filed within two business days whenever a corporate insider — a director, officer, or 10%+ shareholder — buys or sells company stock. Because insiders know their company better than anyone, large open-market purchases are often interpreted as a bullish signal.
What is the cluster buy signal?
A cluster buy is detected when three or more different insiders make open-market purchases (transaction code P) within any 14-day window. Academic research has found cluster buys to be among the most reliable insider trading signals.
What is the difference between a buy, sell, and award?
A buy (code P) is an open-market purchase — the insider spent their own money to acquire shares. A sell (code S) is an open-market sale. An award covers stock grants, restricted stock units (RSUs), and option exercises (codes A, M, R, U). Awards are compensation and are generally not considered as meaningful a signal as open-market buys or sells.
What does 'Scheduled Sale' mean?
A scheduled sale (Rule 10b5-1) means the insider set up an automatic selling plan in advance, usually months before the trades execute. These are less meaningful as bearish signals because the insider was contractually obligated to sell regardless of their current view on the stock.
How far back does the data go?
The tool fetches up to 100 Form 4 filings across the most recent 5 years. For smaller companies with fewer filings, the history may extend further back. For very active companies, the visible history may cover fewer years within that 5-year window.
