Insider Trading Data API

Corporate insiders — officers, directors, and beneficial owners of more than 10% of a company’s stock — must report their transactions to the SEC within two business days. Datastream parses Forms 3, 4, and 5 and exposes structured transaction data through a REST API.

​
What you get

  • Transaction details: Insider name, title, transaction type, shares, price, and value
  • Filtering: By ticker, insider name, transaction type (purchase/sale), and date range
  • Historical data: Form 4 transactions going back to 2004
  • Real-time updates: New filings indexed within minutes

Use cases

​
Insider buying signals

Insider purchases are widely studied as a bullish signal. Insiders sell for many reasons (diversification, taxes, liquidity), but they typically buy for only one: they think the stock is undervalued.

​
Cluster buying detection

When multiple insiders at the same company or across a sector start buying simultaneously, it can indicate strong conviction. Scan groups of tickers for coordinated activity.

​
Compliance monitoring

Track insider activity across your portfolio for regulatory compliance and conflict-of-interest checks.

​
Executive compensation analysis

Combine insider transaction data with compensation data to understand total executive ownership and trading behavior.
