To make the two solutions equivalent you need to think of investing/borrowing $PnL_1$ at fee $r$ making sure that it stays during the method until eventually $t_2,.$ At that time your
I'm interested in figuring out the PnL among $t_0$ and $t_2$ of being long just one unit of dangerous asset. Even so I have two contradictory reasonings:
$begingroup$ You are proper that the overall P&L (or when you contact it The web P&L) need to be the same for the two procedures, so something went Incorrect.
Trader A has designed some significant PnL, In the meantime Trader B will come out with absolutely nothing at all and his missed out on volatility throughout the buying and selling day which he could've profited off of had he been consistently hedging as an alternative to just when a day.
In cases like this, once we measure vol in more compact thirty min increments, we will see it really is appreciably distinctive than vol measured on close to shut price ranges.

$begingroup$ @nbbo2 I'm using the precise price tag path in the instance for any motive, it disproves The premise of delta-hedging frequency not directly influencing PnL. And that i mean "predicted P&L" as the option high quality (PnL) replicated by delta-hedging a situation which can be calculated by subtracting realized volatility from implied volatility.
$begingroup$ Why does Gamma Pnl have publicity to realised volatility, but Vega Pnl only has publicity to implied volatility? I am puzzled regarding why gamma pnl is affected (extra) by IV and why vega pnl isnt impacted (extra) by RV?
The second time period is due to your change in fascination charge. $varepsilon$ is simply what You can not make clear. If every thing is neat, your $varepsilon$ really should not be way too higher. You may as well see that this is very close to a Taylor enlargement when every little thing is linear, Which is the reason You need to use your duration being an approximation for your 2nd time period.
