Detailed Description

Simulation Market updated with discrete scenarios.

If useSpreadedTermStructures is true, spreaded term structures over the initMarket for supported risk factors will be generated. This is used by the SensitivityScenarioGenerator.

If cacheSimData is true, the scenario application is optimised. This requires that all scenarios are SimpleScenario instances with identical key structure in their data.

If allowPartialScenarios is true, the check that all simData_ is touched by a scenario is disabled.

Member Function Documentation

◆ preUpdate()

virtual void preUpdate ( )

overridevirtual

Update.

Implements SimMarket.

◆ updateScenario()

virtual void updateScenario ( const Date & )

overridevirtual

Retrieve next market scenario and apply this, but don't update date.

Implements SimMarket.

◆ updateDate()

virtual void updateDate ( const Date & )

overridevirtual

Update to the given date.

Implements SimMarket.

◆ postUpdate()

virtual void postUpdate	(	const Date &	d,
		bool	withFixings )

overridevirtual

Observable reset depending on selected mode, instrument updates.

Implements SimMarket.

◆ updateAsd()

virtual void updateAsd ( const Date & )

overridevirtual

Update aggregation scenario data.

Implements SimMarket.

◆ reset()

virtual void reset ( )

overridevirtual

Reset sim market to initial state.

Implements SimMarket.

◆ baseScenario()

virtual QuantLib::ext::shared_ptr< Scenario > baseScenario ( ) const

virtual

Scenario representing the initial state of the market. If useSpreadedTermStructures = false, this scenario contains absolute values for all risk factor keys. If useSpreadedTermStructures = true, this scenario contains spread values for all risk factor keys which support spreaded term structures and absolute values for the other risk factor keys. The spread values will typically be zero (e.g. for vol risk factors) or 1 (e.g. for rate curve risk factors, since we use discount factors there).

◆ baseScenarioAbsolute()

virtual QuantLib::ext::shared_ptr< Scenario > baseScenarioAbsolute ( ) const

virtual

Scenario representing the initial state of the market. This scenario contains absolute values for all risk factor types, no matter whether useSpreadedTermStructures is true or false.

◆ offsetScenario()

QuantLib::ext::shared_ptr< Scenario > offsetScenario ( ) const

Get offset scenario, or nullptr if none was set

◆ useSpreadedTermStructures()

bool useSpreadedTermStructures ( ) const

Return true if this instance uses spreaded term structures

◆ fixingManager()

const QuantLib::ext::shared_ptr< FixingManager > & fixingManager ( ) const

overridevirtual

Return the fixing manager.

Implements SimMarket.

◆ getYieldCurve()

QuantLib::Handle< QuantLib::YieldTermStructure > getYieldCurve	(	const std::string &	yieldSpecId,
		const ore::data::TodaysMarketParameters &	todaysMarketParams,
		const std::string &	configuration,
		const QuantLib::ext::shared_ptr< ore::data::Market > &	market = nullptr ) const

protected

Given a yield curve spec ID, yieldSpecId, return the corresponding yield term structure from the market. If market is nullptr, then the yield term structure is taken from this ScenarioSimMarket instance.

◆ addSwapIndexToSsm()

void addSwapIndexToSsm ( const std::string & indexName )

protected

add a single swap index to the market
