Method Detail

presentValueSensitivityRatesStickyModel

public PointSensitivities presentValueSensitivityRatesStickyModel(ResolvedIborCapFloorTrade trade,
                                                                  RatesProvider ratesProvider,
                                                                  SabrIborCapletFloorletVolatilities volatilities)

Calculates the present value rates sensitivity of the Ibor cap/floor trade.

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:

trade - the Ibor cap/floor trade

ratesProvider - the rates provider

volatilities - the volatilities

Returns:

the present value sensitivity

presentValueSensitivityModelParamsSabr

public PointSensitivityBuilder presentValueSensitivityModelParamsSabr(ResolvedIborCapFloorTrade trade,
                                                                      RatesProvider ratesProvider,
                                                                      SabrIborCapletFloorletVolatilities volatilities)

Calculates the present value volatility sensitivity of the Ibor cap/floor trade.

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

Parameters:

trade - the Ibor cap/floor trade

ratesProvider - the rates provider

volatilities - the volatilities

Returns:

the present value sensitivity
