Where can I see SPRO max pain, open interest, and implied volatility in detail?

OptiView publishes dedicated SPRO pages for implied volatility, max pain, open interest, gamma exposure, options volume, and the most active contracts — each with charts, history, and a plain-English explanation of what the numbers mean.

Methodology. IV rank compares the current 30-day at-the-money implied volatility with its highest and lowest values over the past 52 weeks. Max pain is the strike that minimizes the total payout to option holders at expiration. The call and put walls are the strikes carrying the largest call and put open interest across all expirations. Net gamma exposure (GEX) is measured from the dealer perspective. All statistics are derived from delayed OPRA options data.
