Detailed Description

Cross Asset Model Builder.

CrossAssetModelBuilder takes a market snapshot, market conventions (the latter two passed to the constructor), and a model configuration (passed to the "build" member function) to build and calibrate a cross asset model.

Constructor & Destructor Documentation

CrossAssetModelBuilder()

CrossAssetModelBuilder	(	const ObservableValue< QuantLib::ext::shared_ptr< Market > > &	market,
		const QuantLib::ext::shared_ptr< CrossAssetModelData > &	config,
		const std::string &	configurationLgmCalibration = Market::defaultConfiguration,
		const std::string &	configurationFxCalibration = Market::defaultConfiguration,
		const std::string &	configurationEqCalibration = Market::defaultConfiguration,
		const std::string &	configurationInfCalibration = Market::defaultConfiguration,
		const std::string &	configurationCrCalibration = Market::defaultConfiguration,
		const std::string &	configurationFinalModel = Market::defaultConfiguration,
		const bool	dontCalibrate = false,
		const bool	continueOnError = false,
		const std::string &	referenceCalibrationGrid_ = "",
		const std::string &	id = "unknown",
		const bool	allowChangingFallbacksUnderScenarios = false,
		const bool	allowModelFallbacks = false )

The market for the calibration can possibly be different from the final market defining the curves attached to the marginal LGM models; for example domestic OIS curves may be used for the in currency swaption calibration while the global model is operated under FX basis consistent discounting curves relative to the collateral OIS curve.

Parameters

market	Market object
config	cam configuration
configurationLgmCalibration	Market configuration for interest rate model calibration
configurationFxCalibration	Market configuration for FX model calibration
configurationEqCalibration	Market configuration for EQ model calibration
configurationInfCalibration	Market configuration for INF model calibration
configurationCrCalibration	Market configuration for CR model calibration
configurationFinalModel	Market configuration for simulation
dontCalibrate	calibrate the model?
continueOnError	continue if bootstrap error exceeds tolerance
referenceCalibrationGrid_	reference calibration grid
id	id of the builder
allowChangingFallbacksUnderScenarios	allow changing fallbacks under scenarios in lgm sub builders
allowModelFallbacks	allow fallback during model build if market objects are missing (e.g. vol surfaces)
