About this data

Each contract's last price, volume, greeks, implied volatility and open interest belongs to the snapshot session shown in its details; unknown means the provider omitted the timestamp. This chain has mixed snapshot sessions · Jul 24, 2026–Aug 27, 2026; 26 unknown. Cross-contract positioning totals are shown only when every returned row has the same known session. Bid and ask are not included on this plan.

In-the-money strikes are tinted, deepening toward the money, and the bar beside each open-interest figure scales to the heaviest strike shown.
