Vega p/l is by definition the p/l on account of moves in implied volatility. The next A part of the question you've got answered oneself. Brief dated choices have much more gamma publicity, long dated selections have much more vega exposure.
Vega and Theta are sensetivities to volatility and time, respectively, so their contribution can be:
$begingroup$ The theta PnL Here's the choice cost paid (for some time-value of the option); it is just a greek word for it with an extra feature exhibiting how the choice top quality continously declines Along with the passage of your time.
