Spot is trading 23.2 points above the Zero Gamma level (217.4), which puts dealers in net positive gamma: their hedging leans against price moves, and the baseline odds favor compression and mean-reversion over follow-through. The heaviest call-gamma strike (Call Wall) sits at 240 below spot, already breached, and the heaviest put-gamma strike (Put Wall) at 235 underneath; together they frame the band where dealer hedging is concentrated today. Net dealer gamma across all listed expirations totals 1.14 $Bn per 1% move (positive).
NVIDIA's options book has grown into one of the largest in the market by notional gamma, and its hedging flow visibly moves the stock — on big days, the whole index complex feels it. Earnings weeks reshape this map completely: the pre-earnings gamma bulge and the post-print unwind are among the cleanest recurring patterns in single-stock positioning.
These are the same structural levels the free GEX Metrix dashboard draws as charts: dealer hedging pressure, mapped to price. If the mechanics are new, start with what gamma exposure actually is, then the chart-reading walkthrough. Futures traders (ES, NQ) can map these levels directly — here is how.

The strike carrying the heaviest call gamma in the current window — right now 240. As price rallies toward it, dealer hedging leans against the move, which is why the level often behaves as resistance.
The price where net dealer gamma crosses zero — currently 217.4. Above it, hedging dampens moves; below it, hedging amplifies them.
Levels recompute every 15 minutes during US market hours from delayed options data, using expirations from today through the current monthly OpEx (2026-10-16) on the overnight open-interest base. The free dashboard applies our intraday OI model on top of the same base.
Levels on this page are computed from the latest 15-minute delayed snapshot: 582 option series expiring between today and the current monthly OpEx (2026-10-16) — the same default window the dashboard uses (1,453,653 call OI / 1,216,846 put OI). Open interest here is the overnight print, not an intraday estimate. The dashboard additionally runs our intraday OI model on top of this base, so its levels can differ from these raw ones during the session. GEX per option = gamma × OI × 100 × spot² × 0.01, puts negative; Zero Gamma from a Gaussian-weighted profile across ±15% of spot; Max Pain by the intrinsic-value method on the nearest expiration.
