FX Forward and FX Spot

An FX Forward is a financial instrument that represents the exchange of an equivalent amount in two different currencies between counterparties on a specific date in the future. An FX spot is a similar instrument where the payment date is the spot date. These two instruments are referred to as FX Single by Strata.

For example, an FX Single might represent the payment of USD 1,000 and the receipt of EUR 932 on a specific date.

Key classes

An FX Single is represented in Strata using the FxSingle class. The FxSingle class stores details of the product that was agreed. The trade details are stored in FxSingleTrade class.

An FxSingle can be created as follows:

FxSingle fx = FxSingle.of(CurrencyAmount.of(Currency.USD, 1000),
                          FxRate.of(EUR, USD, 1.115),
                          LocalDate.of(2015, 6, 15));

TIP: The strata-loader project provides the ability to load an FX Single from FpML and CSV.
