Detailed Description

A class to calculate SIMM given a set of aggregated CRIF results for one or more portfolios.

Constructor & Destructor Documentation

◆ SimmCalculator()

SimmCalculator	(	const SimmNetSensitivities &	simmNetSensitivities,
		const boost::shared_ptr< SimmConfiguration > &	simmConfiguration,
		const std::string &	calculationCcy = `"USD"`,
		const std::string &	resultCcy = `""`,
		const boost::shared_ptr< ore::data::Market >	market = `nullptr`,
		const bool	determineWinningRegulations = `true`,
		const bool	enforceIMRegulations = `false`,
		const bool	quiet = `false`,
		const std::map< SimmSide, std::set< NettingSetDetails >> &	hasSEC = `std::map< SimmSide, std::set< NettingSetDetails >>()`,
		const std::map< SimmSide, std::set< NettingSetDetails >> &	hasCFTC = `std::map< SimmSide, std::set< NettingSetDetails >>()`
	)

Construct the SimmCalculator from a container of netted CRIF records and a SIMM configuration. The SIMM number is initially calculated in USD using the AmountUSD column. It can optionally be converted to a calculation currency other than USD by using the calculationCcy parameter. If the calculationCcy is not USD then the usdSpot parameter must be used to give the FX spot rate between USD and the calculationCcy. This spot rate is interpreted as the number of USD per unit of calculationCcy.

Member Function Documentation

◆ simmResults()

const std::map<ore::data::NettingSetDetails, std::map<std::string, SimmResults> >& simmResults ( const SimmSide & side ) const

Give back a map containing the SIMM results containers for every portfolio for the given SIMM side. The key is the portfolio ID and the value is the SIMM results container for that portfolio.

◆ finalSimmResults()

const std::map<ore::data::NettingSetDetails, std::pair<std::string, SimmResults> >& finalSimmResults ( const SimmSide & side ) const

Give back a map containing the SIMM results containers for every portfolio for the given SIMM side. The key is the portfolio ID and the value is a map, with regulation as the key, and the value is the SIMM results container for that portfolioId-regulation combination.

◆ populateFinalResults()

void populateFinalResults ( const std::map< SimmSide, std::map< ore::data::NettingSetDetails, std::string >> & winningRegulations )

Populate the finalSimmResults_ and finalAddMargins_ containers using the provided map of winning call/post regulations.
