My broker has provided a risk report that shows our options book shocked at various standard deviation moves of the underlying. Their report has the future at $66.64, ATM Vol at 23.74% with 2 days remaining (I believe they are using a 365 day calendar). How do I get to their 1 standard deviation move of $2.19?
