Group 1 - The financial option implied volatility index reflects the 30 - day implied volatility trend as of the previous trading day, and the commodity option implied volatility index is obtained by weighting the implied volatilities of the two - strike options above and below the at - the - money option of the main contract month, reflecting the implied volatility change trend of the main contract [3] - The difference between the implied volatility index and historical volatility: a larger difference indicates that the implied volatility is relatively higher than historical volatility, and a smaller difference means it is relatively lower [3] Group 2 - The implied volatility quantile represents the current level of a variety's implied volatility in history. A high quantile means the current implied volatility is high, and a low quantile means it is low [5] - The volatility spread is the implied volatility index minus the historical volatility [5]
