irCrossCurrencyCurveBuilder

irCrossCurrencyCurveBuilder(referenceDate, currency, instNames, instTypes, terms, quotes, currencyPair, spot, dayCountConvention, discountCurve, [compounding='Continuous'], [frequency='Annual'], [curveName])

Builds a cross-currency interest rate swap yield curve.

Return value: A MKTDATA object.

referenceDate A DATE scalar specifying the reference date of the yield curve.

currency A STRING scalar specifying the currency code of the curve. Supported values: "CNY", "USD", "EUR", "GBP", "JPY", "HKD".

instNames A STRING vector indicating the instrument names.

instTypes A STRING vector indicating the instrument types.

Currently instTypes only supports "FxSwap", and instNames should be currency pairs, e.g., "USDCNY".

terms A vector of STRING or DURATION type, indicating the remaining maturity, e.g., "1M".

quotes A numeric vector indicating the market quotes.

currencyPair A STRING scalar specifying the currency pair, in the format "EURUSD", "EUR.USD", or "EUR/USD". Supported currency pairs include:

• "EURUSD": Euro to US Dollar

• "USDCNY": US Dollar to Chinese Yuan

• "EURCNY": Euro to Chinese Yuan

• "GBPCNY": British Pound to Chinese Yuan

• "JPYCNY": Japanese Yen to Chinese Yuan

• "HKDCNY": Hong Kong Dollar to Chinese Yuan

spot A DOUBLE scalar specifying the spot exchange rate on the reference date.

dayCountConvention is a STRING scalar or vector indicating the day count convention to use. It can be:

• "ActualActual": actual/actual

• "Actual360": actual/360

• "Actual365": actual/365

• "ActualActualISMA": actual/actual according to ISMA (International Securities Market Association) convention

• "ActualActualISDA": actual/actual according to ISDA (International Swaps and Derivatives Association) convention.

• "Thirty360EU": European 30/360

• "Thirty360US": US (NASD) 30/360

discountCurveA MKTDATA object of type IrYieldCurve, indicating discount curve for the other currency in the currency pair, which must be a yield curve built using the bootstrap method. See Curve Field Specifications for details.

compounding (optional) A STRING scalar defining the compounding method. Options:

• "Compounded": Discrete compounding

• "Simple": Simple interest

• "Continuous" (default): Continuous compounding

frequency (optional) A STRING scalar specifying the interest payment frequency. Supported values:

• "NoFrequency": No payment frequency

• "Annual": Annually

• "Semiannual": Semiannually

• "EveryFourthMonth": Every four months

• "Quarterly": Quarterly

• "BiMonthly": Every two months

• "Monthly": Monthly

• "EveryFourthWeek": Every four weeks

• "BiWeekly": Every two weeks

• "Weekly": Weekly

• "Daily": Daily

• "Other": Other frequencies

curveName (optional) A STRING scalar indicating the yield curve name. The default value is NULL.
