Calculates the present value of the trade.

The present value of the product is based on the valuation date.

This method can calculate the clean or dirty present value, see PriceType. If calculating the clean value, the accrued interest is calculated based on the step-in date.

Parameters:

trade - the trade

ratesProvider - the rates provider

priceType - the price type

refData - the reference data

presentValueOnSettleSensitivity

public PointSensitivities presentValueOnSettleSensitivity(ResolvedCdsTrade trade,

                                    PriceType priceType,
                                    ReferenceData refData)

Calculates the risky PV01 of the underlying product.

RPV01 is defined as minus of the present value sensitivity to coupon rate.

This is computed based on the settlement date rather than the valuation date.

Parameters:

recovery01OnSettle

public CurrencyAmount recovery01OnSettle(ResolvedCdsTrade trade,

Calculates the recovery01 of the underlying product.

The recovery01 is defined as the present value sensitivity to the recovery rate. Since the ISDA standard model requires the recovery rate to be constant throughout the lifetime of the CDS, one currency amount is returned by this method.

This is computed based on the settlement date rather than the valuation date.

Parameters:

trade - the trade

ratesProvider - the rates provider

refData - the reference data

Returns:

the recovery01

The jump-to-default is the value of the product in case of immediate default.

Parameters:

trade - the trade

ratesProvider - the rates provider

refData - the reference data

ratesProvider - the rates provider

Returns:

the expected loss
