presentValue

public MultiCurrencyAmount presentValue(ResolvedIborCapFloorTrade trade,
                                        RatesProvider ratesProvider,
                                        IborCapletFloorletVolatilities volatilities)

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

The present value of the trade is the value on the valuation date.

The cap/floor leg and pay leg are typically in the same currency, thus the present value gamma is expressed as a single currency amount in most cases.

Parameters:

trade - the Ibor cap/floor trade

ratesProvider - the rates provider

volatilities - the volatilities

Returns:

the present value

presentValueCapletFloorletPeriods

public IborCapletFloorletPeriodCurrencyAmounts presentValueCapletFloorletPeriods(ResolvedIborCapFloorTrade trade,
                                                                                 RatesProvider ratesProvider,

Calculates the present value for each caplet/floorlet of the Ibor cap/floor trade.

The present value of each caplet/floorlet is the value on the valuation date. The result is returned using the payment currency of the leg.

The present value will not be calculated for the trade premium or for the pay leg if the cap/floor product has one.

Parameters:

trade - the Ibor cap/floor leg

ratesProvider - the rates provider

volatilities - the volatilities

Returns:

the present values
