$begingroup$ When you have a time number of gathered/on going PnL figures, $X_t$, you need to be mindful to convert these into a more stationary data number of interval PnL improvements (possibly day-to-day adjustments):

Nivel Egres: In the perspective of gamma pnl, the only thing that issues is definitely the improve in the asset value. Frequency is irrelevant - you are able to rebalance at distinct time periods or when delta exceeds a threshold or all kinds of other matters - it remains to be an approximation of ongoing integral along with your anticipated P&L could be the same.

So if I invest in a possibility and delta hedge then I earn money on gamma but drop on theta and these two offset one another. Then how can I Get well possibility price from delta hedging i.e. shouldn't my pnl be equal to the option cost paid?

Now, in the above mentioned clarification, we assumed the inventory was undertaking on some regular vol in the slightest degree times in time.
