Class DsfTradeCalculations

java.lang.Object

com.opengamma.strata.measure.dsf.DsfTradeCalculations

public class DsfTradeCalculations
extends Object

Calculates pricing and risk measures for Deliverable Swap Future (DSF) trades.

This provides a high-level entry point for DSF pricing and risk measures.

Each method takes a ResolvedDsfTrade, whereas application code will typically work with DsfTrade. Call DsfTrade::resolve(ReferenceData) to convert DsfTrade to ResolvedDsfTrade.

Price

The price of a DSF is based on the present value (NPV) of the underlying swap on the delivery date. For example, a price of 100.182 represents a present value of $100,182.00, if the notional is $100,000. This price can also be viewed as a percentage present value - (100 + percentPv), or 0.182% in this example.

Strata uses decimal prices for DSFs in the trade model, pricers and market data. The decimal price is based on the decimal multiplier equivalent to the implied percentage. Thus the market price of 100.182 is represented in Strata by 1.00182.
