Detailed Description

Plain-vanilla swap: fix vs floating leg.

If no payment convention is passed, the convention of the floating-rate schedule is used.

Warning

if Settings::includeReferenceDateCashFlows() is set to true, payments occurring at the settlement date of the swap might be included in the NPV and therefore affect the fair-rate and fair-spread calculation. This might not be what you want.

Tests

*

the correctness of the returned value is tested by checking that the price of a swap paying the fair fixed rate is null.

*

the correctness of the returned value is tested by checking that the price of a swap receiving the fair floating-rate spread is null.

*

the correctness of the returned value is tested by checking that the price of a swap decreases with the paid fixed rate.

*

the correctness of the returned value is tested by checking that the price of a swap increases with the received floating-rate spread.

*

the correctness of the returned value is tested by checking it against a known good value.

Examples:

BermudanSwaption.cpp, and swapvaluation.cpp.

Member Function Documentation

void setupArguments (PricingEngine::arguments *) const [virtual]When a derived argument structure is defined for an instrument, this method should be overridden to fill it. This is mandatory in case a pricing engine is used.

Reimplemented from Swap.

void fetchResults (const PricingEngine::results * r) const [virtual]When a derived result structure is defined for an instrument, this method should be overridden to read from it. This is mandatory in case a pricing engine is used.

Reimplemented from Swap.
