20 contracts expiring August 21, 2026. Greeks, implied volatility, open interest and the last price come from the latest daily snapshot and are 15-minute delayed. In-the-money strikes are shaded and deepen toward the money; the strike nearest the underlying is highlighted, and the bar under each open-interest figure scales to the heaviest strike shown. Click any strike for its greeks, breakevens and to model it in the calculator on the market's own implied volatility. Max pain is the listed strike where the most open interest would expire worthless — a positioning reference, not a forecast.
