Using calendar days (365) vs trading days (252) to calc IV makes a difference, especially as expiration date approaches. An empirical check to prove which is more efficacious exists. This check is called "Monday." Friday-to-Monday IV should be significantly higher if, indeed, calendar days is the better measure -- i.e. 3/365's vs 1/252'nd. This is not the case.
Is it good but way before earnings then sell when close to earning as price goes up
I’d buy you both a beer but instead ill just say thank you for this!
Thanks
