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: ZeroStack Corp., SEC CIK 0001790169. The symbol on a Form 4 is typed by the filer, so this page follows the issuer with the newest filing under ZSTK and shows every filing by that issuer (also filed as FLGC).
Coverage: Form 4 filings indexed 2006-01-02 → 2026-09-15. Earlier history is backfilling; this window widens as it deepens.
