# SPX — Max Pain / GEX · GammaGrid demo **Gamma weather: Storm.** This chain has no gamma flip within 25% of the price, so only the sign of gamma is known — negative, hedging amplifies moves. *(next 30 days · 22 expiries)* | Level | Value | |---|---| | Price | 7,528.55 | | Call wall | 8,100.00 | | Put wall | 6,400.00 | | Gamma flip | — | | Net GEX | -298.9 M | ## Max pain and dealer gamma by expiry Nearest expiries first. Max pain is the strike where open interest would expire worth the least; the expected move is one standard deviation from at-the-money implied volatility; net GEX is the dealers' estimated gamma exposure for that expiry, positive damps moves and negative amplifies them. | Expiry | Max pain | Expected move | Range | Call wall | Put wall | Net GEX | Contracts | |---|---|---|---|---|---|---|---| | 2026-11-09 | 7,515.00 | ±0.4% | 7,499.82 – 7,557.28 | 7,550.00 | 6,400.00 | 181.3 M | 464 | | 2026-11-10 | 7,570.00 | ±1.1% | 7,446.15 – 7,610.95 | 7,805.00 | 6,950.00 | -21.6 M | 431 | | 2026-11-11 | 7,590.00 | ±1.5% | 7,417.06 – 7,640.04 | 7,850.00 | 6,200.00 | -79.5 M | 430 | | 2026-11-12 | 7,610.00 | ±1.8% | 7,395.18 – 7,661.92 | 8,000.00 | 6,200.00 | -15.3 M | 411 | | 2026-11-13 | 7,600.00 | ±2.0% | 7,374.99 – 7,682.11 | 7,850.00 | 6,400.00 | -45.1 M | 526 | | 2026-11-16 | 7,660.00 | ±2.3% | 7,355.36 – 7,701.74 | 7,930.00 | 6,000.00 | -18.5 M | 381 | 54 expiries in the chain; the page lists every one. ## About these numbers Computed by GammaGrid from the SPX options chain — dealer gamma exposure, max pain and the walls are GammaGrid's own arithmetic over open interest; the source data is delayed.
