com.opengamma.strata.pricer.index.NormalIborFutureOptionMarginedProductPricer

public class NormalIborFutureOptionMarginedProductPricer
extends Object

Pricer of options on Ibor future with a normal model on the underlying future price.

This provides the ability to price an Ibor future option. The option must be based on daily margin.

Price

The price of an Ibor future option is based on the price of the underlying future, the volatility and the time to expiry. The price of the at-the-money option tends to zero as expiry approaches.

Strata uses decimal prices for Ibor future options in the trade model, pricers and market data. The decimal price is based on the decimal rate equivalent to the percentage. For example, an option price of 0.2 is related to a futures price of 99.32 that implies an interest rate of 0.68%. Strata represents the price of the future as 0.9932 and thus represents the price of the option as 0.002.

NormalIborFutureOptionMarginedProductPricer

public NormalIborFutureOptionMarginedProductPricer(DiscountingIborFutureProductPricer futurePricer)

Creates an instance.

Parameters:

futurePricer - the pricer for IborFutureOption

Method Detail

price

public double price(ResolvedIborFutureOption futureOption,
                    RatesProvider ratesProvider,
                    NormalIborFutureOptionVolatilities volatilities)

Calculates the price of the Ibor future option product.

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

This calculates the underlying future price using the future pricer.

Parameters:

futureOption - the option product

ratesProvider - the rates provider

volatilities - the volatilities

Returns:

the price of the product, in decimal form

public double price(ResolvedIborFutureOption futureOption,
                    RatesProvider ratesProvider,
                    NormalIborFutureOptionVolatilities volatilities,
                    double futurePrice)

Calculates the price of the Ibor future option product based on the price of the underlying future.

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

Parameters:

futureOption - the option product

ratesProvider - the rates provider

volatilities - the volatilities

futurePrice - the price of the underlying future, in decimal form

Returns:

the price of the product, in decimal form

deltaStickyStrike

public double deltaStickyStrike(ResolvedIborFutureOption futureOption,
                                RatesProvider ratesProvider,
                                NormalIborFutureOptionVolatilities volatilities)

Calculates the delta of the Ibor future option product.

The delta of the product is the sensitivity of the option price to the future price. The volatility is unchanged for a fixed strike in the sensitivity computation, hence the "StickyStrike" name.

This calculates the underlying future price using the future pricer.

Parameters:

futureOption - the option product

ratesProvider - the rates provider

volatilities - the volatilities

Returns:

the price curve sensitivity of the product
