Detailed Description

Variance option.

Warning:
This class does not manage seasoned variance options.

Definition at line 39 of file varianceoption.hpp.

Constructor & Destructor Documentation

◆ VarianceOption()

VarianceOption ( ext::shared_ptr< Payoff payoff,
Real  notional,
const Date startDate,
const Date maturityDate 
)

Definition at line 26 of file varianceoption.cpp.

Member Function Documentation

◆ isExpired()

bool isExpired ( ) const
overridevirtual

returns whether the instrument might have value greater than zero.

Implements Instrument.

Definition at line 51 of file varianceoption.cpp.

+ Here is the call graph for this function:

◆ startDate()

Date startDate ( ) const

Definition at line 92 of file varianceoption.hpp.

◆ maturityDate()

Date maturityDate ( ) const

Definition at line 96 of file varianceoption.hpp.

◆ notional()

Real notional ( ) const

Definition at line 100 of file varianceoption.hpp.

◆ payoff()

ext::shared_ptr< Payoff > payoff ( ) const

Definition at line 104 of file varianceoption.hpp.

◆ setupArguments()

void setupArguments ( PricingEngine::arguments ) const
overridevirtual

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.

Definition at line 33 of file varianceoption.cpp.
