iv implied volatility at 30 days interpolated
ivRank1m A measure of implied volatility vs its past 1 month values, but it looks only at the highest and lowest values. Formula is (Current IV - 1 month Low IV) / (1 month Max - 1 month Min)
ivPct1m A measure of implied volatility vs its past 1 month values. If IV percentile is 36% – It means that current IV value is higher than 36% of previous 1 month values (and lower than 64% of them).
ivRank1y A measure of implied volatility vs its 1 year past values, but it looks only at the highest and lowest values. Formula is (Current IV - 1 yr Low IV) / (1 yr Max - 1 yr Min)
ivPct1y A measure of implied volatility vs its past 1 year values. If IV percentile is 36% – It means that current IV value is higher than 36% of previous 1 year values (and lower than 64% of them).
