Method
IV30 is the at-the-money implied volatility of the expiration nearest 30 days (call and put averaged), solved from closing option prices and stored once per session for every ticker in the universe since July 2025. HV30 is 30-trading-day close-to-close realized volatility. Month start and end are each ticker's first and last stored session in the month. Dealer gamma sessions come from the nightly capture of the full SPY and QQQ chains. Names with fewer than 30 stored tickers in a month produce no IV section.
