Syntax

fxForwardPricer(instrument, pricingDate, spot, domesticCurve, foreignCurve)

Details

Computes the Net Present Value (NPV) of an FX forward contract based on the given spot rate, domestic and foreign discount curves, and the pricing date.

Return value: A DOUBLE scalar.

Arguments

instrument An INSTRUMENT object of type FxForward, representing the FX forward to be priced. See Product Field Specifications for details.

pricingDate A DATE scalar specifying the pricing date.

spot A DOUBLE scalar representing the spot exchange rate.

domesticCurve A MKTDATA object of type IrYieldCurve representing the domestic discount curve. See Curve Field Specifications for details.

foreignCurve A MKTDATA object of type IrYieldCurve representing the foreign discount curve. See Curve Field Specifications for details.
