About this data

Each contract's last price, day range and volume belong to the daily-bar session shown in its details; unknown means the source omitted that timestamp. Open interest has its own effective date shown separately; implied volatility and greeks are model values computed when fetched. This chain has mixed daily-bar sessions · May 15, 2026–Sep 4, 2026; 15 unknown. Positioning totals are shown only when every returned open-interest value has the same known effective date. Bid and ask are real-time consolidated OPRA readings.

In-the-money strikes are tinted, deepening toward the money, and the bar beside each open-interest figure scales to the heaviest strike shown. Max pain is the listed strike where the most open interest would expire worthless — a positioning reference, not a forecast.
