Detailed Description

Base class for cap-like instruments.

Tests

*

the correctness of the returned value is tested by checking that the price of a cap (resp. floor) decreases (resp. increases) with the strike rate.

*

the relationship between the values of caps, floors and the resulting collars is checked.

*

the put-call parity between the values of caps, floors and swaps is checked.

*

the correctness of the returned implied volatility is tested by using it for reproducing the target value.

*

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

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 Instrument.
