com.opengamma.strata.pricer.capfloor.SabrIborCapletFloorletPeriodPricer

public class SabrIborCapletFloorletPeriodPricer
extends VolatilityIborCapletFloorletPeriodPricer

Pricer for caplet/floorlet in SABR model.

The value of the caplet/floorlet after expiry is a fixed payoff amount. The value is zero if valuation date is after payment date of the caplet/floorlet.

Method Detail

validate

protected void validate(IborCapletFloorletVolatilities volatilities)

Description copied from class: VolatilityIborCapletFloorletPeriodPricer

Validate the volatilities provider.

This validate method should be overridden such that a correct implementation of IborCapletFloorletVolatilities is used for pricing.

Overrides:

validate in class VolatilityIborCapletFloorletPeriodPricer

Parameters:

volatilities - the volatilities

presentValueSensitivityRatesStickyModel

public PointSensitivityBuilder presentValueSensitivityRatesStickyModel(IborCapletFloorletPeriod period,
                                                                       RatesProvider ratesProvider,
                                                                       SabrIborCapletFloorletVolatilities volatilities)

Calculates the present value sensitivity of the Ibor caplet/floorlet to the rate curves.

The present value sensitivity is computed in a "sticky model parameter" style, i.e. the sensitivity to the curve nodes with the SABR model parameters unchanged. This sensitivity does not include a potential re-calibration of the model parameters to the raw market data.

Parameters:

period - the Ibor caplet/floorlet period

ratesProvider - the rates provider

volatilities - the volatilities

Returns:

the point sensitivity to the rate curves

presentValueSensitivityModelParamsSabr

public PointSensitivityBuilder presentValueSensitivityModelParamsSabr(IborCapletFloorletPeriod period,
                                                                      RatesProvider ratesProvider,
                                                                      SabrIborCapletFloorletVolatilities volatilities)

Calculates the present value sensitivity to the SABR model parameters of the Ibor caplet/floorlet.

The sensitivity of the present value to the SABR model parameters, alpha, beta, rho and nu.

Parameters:

period - the Ibor caplet/floorlet period

ratesProvider - the rates provider

volatilities - the volatilities

Returns:

the point sensitivity to the SABR model parameters
