Detailed Description

Swaption class

Tests

*
the correctness of the returned value is tested by checking that the price of a payer (resp. receiver) swaption decreases (resp. increases) with the strike.
*
the correctness of the returned value is tested by checking that the price of a payer (resp. receiver) swaption increases (resp. decreases) with the spread.
*
the correctness of the returned value is tested by checking it against that of a swaption on a swap with no spread and a correspondingly adjusted fixed rate.
*
the correctness of the returned value is tested by checking it against a known good value.
*
the correctness of the returned value of cash settled swaptions is tested by checking the modified annuity against a value calculated without using the Swaption class.

Possible enhancements

add greeks and explicit exercise lag

Examples:

BermudanSwaption.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 Option.
