Group 1: Implied Volatility Index and Historical Volatility - The financial option implied volatility index reflects the 30 - day implied volatility (IV) trend as of the previous trading day. The commodity option implied volatility index is obtained by weighting the IV of the two - strike options above and below the at - the - money option of the main contract, reflecting the IV change trend of the main contract [2] - The difference between the IV index and historical volatility (HV) indicates the relative level of IV to HV. A larger difference means higher IV relative to HV, and a smaller difference means lower IV relative to HV [2] Group 2: Implied Volatility Index and Volatility Spread Quantile Ranking - Implied volatility quantile represents the current level of a variety's IV in history. A high quantile means the current IV is high, and a low quantile means the current IV is low. Volatility spread is IV minus HV [4] - The implied volatility quantile rankings of some varieties are as follows: 300 Index (0.83), China Securities (0.84), PTA (0.80), 5 - year (0.43), 50ETF (0.39), PVC (0.38), etc. The historical volatility quantile rankings of some varieties are also presented, such as PTA (0.27) [4][5]

Group 1: Implied Volatility Index and Its Calculation - The implied volatility index of financial options reflects the 30 - day implied volatility (IV) trend as of the previous trading day.
