Detailed Description

Discrete-averaging Asian option.

Constructor & Destructor Documentation

DiscreteAveragingAsianOption() [1/2]

DiscreteAveragingAsianOption	(	Average::Type	averageType,
		Real	runningAccumulator,
		Size	pastFixings,
		std::vector< Date >	fixingDates,
		const ext::shared_ptr< StrikedTypePayoff > &	payoff,
		const ext::shared_ptr< Exercise > &	exercise )

This constructor takes the running sum or product of past fixings, depending on the average type. The fixing dates passed here can be only the future ones.

DiscreteAveragingAsianOption() [2/2]

DiscreteAveragingAsianOption	(	Average::Type	averageType,
		std::vector< Date >	fixingDates,
		const ext::shared_ptr< StrikedTypePayoff > &	payoff,
		const ext::shared_ptr< Exercise > &	exercise,
		std::vector< Real >	allPastFixings = std::vector< Real >() )

This constructor takes past fixings as a vector, defaulting to an empty vector representing an unseasoned option. This constructor expects all fixing dates to be provided, including those in the past, and to be already sorted. During the calculations, the option will compare them to the evaluation date to determine which are historic; it will then take as many values from allPastFixings as needed and ignore the others. If not enough fixings are provided, it will raise an error.

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.
