com.opengamma.strata.market.curve.node.FraCurveNode

All Implemented Interfaces:

CurveNode, Serializable, org.joda.beans.Bean, org.joda.beans.ImmutableBean

public final class FraCurveNode
extends Object
implements CurveNode, org.joda.beans.ImmutableBean, Serializable

A curve node whose instrument is a Forward Rate Agreement (FRA).

The trade produced by the node will be a fixed rate receiver (SELL) for a positive quantity and a payer (BUY) for a negative quantity. This convention is line with other nodes where a positive quantity is similar to long a bond or deposit.

Determines the market data that is required by the node.

This returns the market data needed to build the trade that the node represents.

Specified by:

requirements in interface CurveNode

Returns:

requirements for the market data needed to build a trade representing the instrument at the node

date

public LocalDate date(LocalDate valuationDate,
                      ReferenceData refData)

Description copied from interface: CurveNode

Calculates the date associated with the node.

Each curve node has an associated date which defines the x-value in the curve. This date is visible in the parameter metadata.

Specified by:

date in interface CurveNode

Parameters:

valuationDate - the valuation date used when calibrating the curve

refData - the reference data to use to resolve the trade

Returns:

the date associated with the node

metadata

public DatedParameterMetadata metadata(LocalDate valuationDate,
                                       ReferenceData refData)

Description copied from interface: CurveNode

Returns metadata for the node.

This provides curve metadata for the node at the specified valuation date.

Specified by:

metadata in interface CurveNode

Parameters:

valuationDate - the valuation date used when calibrating the curve

refData - the reference data to use to resolve the trade

Returns:

metadata for the node

trade

public FraTrade trade(double quantity,
                      MarketData marketData,
                      ReferenceData refData)

Description copied from interface: CurveNode

Creates a trade representing the instrument at the node.

This uses the observed market data to build the trade that the node represents. The reference data is typically used to find the start date of the trade from the valuation date. The resulting trade is not resolved. The notional of the trade is taken from the 'quantity' variable. The quantity is signed and will affect whether the trade is Buy or Sell. The valuation date is defined by the market data.

Specified by:

trade in interface CurveNode

Parameters:

quantity - the quantity or notional of the trade

marketData - the market data required to build a trade for the instrument, including the valuation date

refData - the reference data, used to resolve the trade dates

Returns:

a trade representing the instrument at the node

resolvedTrade

public ResolvedFraTrade resolvedTrade(double quantity,
                                      MarketData marketData,
                                      ReferenceData refData)

Description copied from interface: CurveNode

Creates a resolved trade representing the instrument at the node.

This uses the observed market data to build the trade that the node represents. The trade is then resolved using the specified reference data if necessary. The valuation date is defined by the market data.

Resolved objects may be bound to data that changes over time, such as holiday calendars. If the data changes, such as the addition of a new holiday, the resolved form will not be updated. Care must be taken when placing the resolved form in a cache or persistence layer.

Specified by:

resolvedTrade in interface CurveNode

Parameters:

quantity - the quantity or notional of the trade

marketData - the market data required to build a trade for the instrument, including the valuation date

refData - the reference data, used to resolve the trade

Returns:

a trade representing the instrument at the node

sampleResolvedTrade

public ResolvedFraTrade sampleResolvedTrade(LocalDate valuationDate,
                                            FxRateProvider fxProvider,
                                            ReferenceData refData)

Description copied from interface: CurveNode

Creates a resolved trade representing the instrument at the node.

This uses an arbitrary quantity, typically 1, and an arbitrary market data quote, typically 0, to create a trade. This is useful when the trade is to be used to calculate the current par value. The FX provider is typically only used for cross-currency trades. In many cases, FxRateProvider.minimal() can be passed in.

Resolved objects may be bound to data that changes over time, such as holiday calendars. If the data changes, such as the addition of a new holiday, the resolved form will not be updated. Care must be taken when placing the resolved form in a cache or persistence layer.

Specified by:

sampleResolvedTrade in interface CurveNode

Parameters:

valuationDate - the valuation date

fxProvider - the FX rate provider

refData - the reference data, used to resolve the trade

Returns:

a trade representing the instrument at the node

initialGuess

public double initialGuess(MarketData marketData,
                           ValueType valueType)

Description copied from interface: CurveNode

Gets the initial guess used for calibrating the node.

This uses the observed market data to select a suitable initial guess. For example, a Fixed-Ibor swap would return the market quote, which is the fixed rate, providing that the value type is 'ZeroRate'. The valuation date is defined by the market data.

This is primarily used as a performance hint. Since the guess is refined by calibration, in most cases any suitable number can be returned, such as zero.

Specified by:

initialGuess in interface CurveNode

Parameters:

marketData - the market data required to build a trade for the instrument, including the valuation date

valueType - the type of y-value that the curve will contain

Returns:

the initial guess of the calibrated value
