EQequibles
Options

One expiration's positioning, computed from the live chain: open interest and volume by side with put/call ratios, max pain, at-the-money implied volatility, the at-the-money straddle's mid as a market-implied expected move, 25-delta skew, unsigned gross gamma by strike, and the contracts trading heaviest against their open interest. Defaults to the nearest upcoming expiration. A figure that needs the whole chain or one open-interest date is null rather than computed over part of it. Nothing here is a forecast, and gamma carries no dealer sign. Pro reads real-time quotes and Plus delayed indicative quotes; the Free plan covers end-of-day data only and receives 403. US listings only.
