Insider transactions sourced from SEC EDGAR Form 4 filings, normalized within minutes of acceptance. "Buy"/"Sell" mark open-market transactions (codes P/S), the tradeable signal. Awards, option exercises and tax-withholding are shown with their raw code. All data is public domain.
Issuer: Oil States International, Inc, SEC CIK 0001121484. The symbol on a Form 4 is typed by the filer, so this page follows the issuer with the newest filing under OIS and shows every filing by that issuer.
Coverage: Form 4 filings indexed 2006-01-02 → 2026-09-11. Earlier history is backfilling; this window widens as it deepens.
Programmatic access via the Arkolith API & MCP server (insider.transactions, insider.company).
