Data Source

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.

Coverage: Form 4 filings indexed 2021-03-29 → 2026-07-14. Earlier history is backfilling; this window widens as it deepens.

Programmatic access via the Arkolith API & MCP server (insider.transactions, insider.company).
