As well as incremental PnL of an extended system among $t$ and $t+delta t$ is calculated because the profit produced by borrowing the money to purchase the risky belongings at $t$, then promoting out your position at $t+delta t$. So in my illustration:
$begingroup$ In case you have a time series of accrued/on going PnL figures, $X_t$, try to be thorough to convert these into a much more stationary information series of interval PnL variations (possibly each day modifications):
. y ahora escribo con la derecha pero uso la mano izquierda mejor a veces q la derecha,, cómo sería esto? por ejemplo me gusta el arte pero me doy cuenta q no logro realizarme en eso..puede tener que ver lo que me ha pasado de chica? Responder
