volatility

default double volatility(ZonedDateTime expiryDateTime,
                          double strike,
                          double forward)

Calculates the volatility at the specified expiry.

Parameters:

expiryDateTime - the option expiry

strike - the option strike rate

forward - the forward rate

Returns:

the volatility

Throws:

RuntimeException - if the value cannot be obtained

volatility

double volatility(double expiry,
                  double strike,
                  double forward)

Calculates the volatility at the specified expiry.

This relies on expiry supplied by relativeTime(ZonedDateTime).

Parameters:

expiry - the time to expiry as a year fraction

strike - the option strike rate

forward - the forward rate

Returns:

the volatility

Throws:

RuntimeException - if the value cannot be obtained

parameterSensitivity

default CurrencyParameterSensitivities parameterSensitivity(PointSensitivity... pointSensitivities)

Calculates the parameter sensitivity.

This computes the CurrencyParameterSensitivities associated with the PointSensitivities. This corresponds to the projection of the point sensitivity to the internal parameters representation.

Parameters:

pointSensitivities - the point sensitivities

Returns:

the sensitivity to the underlying parameters

parameterSensitivity

CurrencyParameterSensitivities parameterSensitivity(PointSensitivities pointSensitivities)

Calculates the parameter sensitivity.

This computes the CurrencyParameterSensitivities associated with the PointSensitivities. This corresponds to the projection of the point sensitivity to the internal parameters representation.

Parameters:

pointSensitivities - the point sensitivities

Returns:

the sensitivity to the underlying parameters

price

double price(double expiry,
             PutCall putCall,
             double strike,
             double forward,
             double volatility)

Calculates the price.

This relies on expiry supplied by relativeTime(ZonedDateTime). This relies on volatility supplied by volatility(double, double, double).

Parameters:

expiry - the time to expiry as a year fraction

putCall - whether the option is put or call

strike - the option strike rate

forward - the forward rate

volatility - the volatility

Returns:
