rabais est le montant devant être payé à l'échéance si la barrière est atteinte.

Mis_ou_appelé est une chaîne qui définit si l'option est mise ("p") ou appelée ("c").

InOut is a string that defines whether the option is knock-in (“i”) or knock-out (“o”).

BarrierMonitoring is a string that defines whether the barrier is monitored continuously (“c”) or only at the end / maturity (“e”).

Greek (optional) is a string argument. If omitted or set to “value”, “v”, “price”, or “p”, then the function simply returns the option price. If another valid string is entered, the function returns price sensitivities (Greeks) to one of the input parameters. The valid options in this case are as follows.

- “delta” or “d”.

- “gamma” or “g”.

- “theta” or “t”.

- “vega” or “e”.

- “volga” or “o”.

- “vanna” or “a”.

- “rho” or “r”.

- “rhof” or “f”.
