$ In the "function situation" you liquidate the portfolio at $t_1$ realising its PnL (allow me to simplify the notation a tiny bit)
La PNL es un modelo que busca entender cómo las personas estructuran sus experiencias subjetivas y cómo pueden modificar sus patrones de pensamiento y comportamiento para alcanzar sus objetivos.
Or does it really not make any difference? I suggest the two can return different values so I have to question which price is a lot more exact. $endgroup$
so That which you shed on top quality payment you gain with your gamma investing account and you also crack even as you expect!
The online impact of all of that is the fact increased delta hedging frequency does just possess the smoothing impact on P/L over prolonged plenty of time horizons. But such as you indicate you happen to be subjected to a person-off or uncommon indicate reversion (or development) effects, but these dissipate above massive samples.

There might be no scientific solution to derive a "appropriate" process.
Two traders have bought a one hundred strike ATM straddle (very long gamma) that read more expires in per week on stock XYZ. The stock price tag is 100. These are both originally delta neutral. During expiry, Trader A delta-hedges each individual minute, and trader B hedges each conclusion of working day at industry near.
