## About these numbers

Computed by GammaGrid from the NVDA options chain — dealer gamma exposure, max pain and the walls are GammaGrid's own arithmetic over open interest; the source data is delayed. Collected 2026-09-13T04:11:44.824639 UTC; this page follows the collection, roughly every fifteen minutes while the market is open.
