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
