In this instance, whenever we evaluate vol in smaller sized thirty min increments, we could see it is appreciably various than vol measured on near to close prices.

At the conclusion of the working day, the EV/Avg(PNL) boils right down to iv vs rv of stock. If those two are equal, then the EV/PNL will be the exact for both traders irrespective of hedging frequency. The sole variance will be the variance in their PNL as explained higher than.

But you will need to consider the query in A much bigger photograph sense. How would hedging frequency have an effect on the final results over A huge number of simulations?

Since's an important range (that will get noted, etcetera.) but that doesn't provide you with a great deal of data on what created that pnl. The second phase website is to maneuver every variable that could influence your pnl to evaluate the contribution that a change in this variable has on the entire pnl.

The 2nd phrase is because of your adjust in interest fee. $varepsilon$ is solely what You cannot demonstrate. If everything is neat, your $varepsilon$ really should not be also superior. You may also see this is extremely near a Taylor expansion when all the things is linear, Which explains why You may use your duration as an approximation to the 2nd time period.
