Class HullWhiteIborFutureProductPricer


  • public class HullWhiteIborFutureProductPricer
    extends Object
    Pricer for for Ibor future products.

    This function provides the ability to price a IborFuture based on Hull-White one-factor model with piecewise constant volatility.

    Price

    The price of an Ibor future is based on the interest rate of the underlying index. It is defined as (100 - percentRate).

    Strata uses decimal prices for Ibor futures in the trade model, pricers and market data. The decimal price is based on the decimal rate equivalent to the percentage. For example, a price of 99.32 implies an interest rate of 0.68% which is represented in Strata by 0.9932.

      • price

        public double price​(ResolvedIborFuture future,
                            RatesProvider ratesProvider,
                            HullWhiteOneFactorPiecewiseConstantParametersProvider hwProvider)
        Calculates the price of the Ibor future product.

        The price of the product is the price on the valuation date.

        Parameters:
        future - the future
        ratesProvider - the rates provider
        hwProvider - the Hull-White model parameter provider
        Returns:
        the price of the product, in decimal form
      • convexityAdjustment

        public double convexityAdjustment​(ResolvedIborFuture future,
                                          RatesProvider ratesProvider,
                                          HullWhiteOneFactorPiecewiseConstantParametersProvider hwProvider)
        Calculates the convexity adjustment (to the price) of the Ibor future product.

        The convexity adjustment of the product is the value on the valuation date.

        Parameters:
        future - the future
        ratesProvider - the rates provider
        hwProvider - the Hull-White model parameter provider
        Returns:
        the convexity adjustment, in decimal form
      • parRate

        public double parRate​(ResolvedIborFuture future,
                              RatesProvider ratesProvider,
                              HullWhiteOneFactorPiecewiseConstantParametersProvider hwProvider)
        Calculates the par rate of the Ibor future product.

        The par rate is given by (1 - price). The par rate of the product is the value on the valuation date.

        Parameters:
        future - the future
        ratesProvider - the rates provider
        hwProvider - the Hull-White model parameter provider
        Returns:
        the par rate of the product, in decimal form

        Calculates the price sensitivity of the Ibor future product.

        The price sensitivity of the product is the sensitivity of the price to the underlying curves.

        Parameters:
        future - the future
        ratesProvider - the rates provider
        hwProvider - the Hull-White model parameter provider
        Returns:
        the price curve sensitivity of the product
