Member Function Documentation

coefficient TreeProductEuropeanSeller::current_price	(	const PiecewiseLinear &	current,
		const Portfolio &	holdings = Portfolio(0, 0)
	)		const [inline, virtual]

Computes current price of option, given the holdings of the investor

Parameters:

current	Lower boundary of set of hedging portfolios
holdings	Current holdings of investor

Implements TreeProduct.

Reimplemented in TreeProductEuropeanBuyer.

coefficient TreeProduct::expiry

(

)

const [inline, inherited]

Expiry time.

PiecewiseLinear TreeProductEuropeanSeller::final_hedge

(

const Spot &

spot

)

const [inline, virtual]

Finds set of portfolios that hedges the option at its expiry time.

Parameters:

spot	Price of underlying asset

Returns:

Piecewise linear function that gives the lower boundary of set of hedging portfolios

Implements TreeProduct.

Reimplemented in TreeProductEuropeanBuyerOptional, and TreeProductEuropeanSellerOptional.

PiecewiseLinear TreeProductEuropean::interim_hedge	(	const coefficient	t,
		const Spot &	spot,
		const PiecewiseLinear &	future_hedge
	)		const [inline, virtual, inherited]

At an interim time step, finds set of portfolios that hedges the payoff of the option in the future

Parameters:

t	Time
spot	Price of underlying asset
future_hedge	Piecewise linear function whose epigraph consist of portfolios that hedge the option at all future time steps

Returns:

Piecewise linear function that gives the lower boundary of set of hedging portfolios

Implements TreeProduct.

Portfolio TreeProduct::next_portfolio	(	const coefficient	t,
		const Spot &	spot,
		const PiecewiseLinear &	future_hedge,
		const Portfolio &	current_portfolio
	)		const [inline, inherited]

Given a portfolio that hedges at the current time, computes a portfolio into which the trader can enter that hedges at all future times

Parameters:

t	Time
spot	Price of underlying asset
future_hedge	Piecewise linear function whose epigraph consist of portfolios that hedge the option at all future time steps
current_portfolio	Current portfolio. Must correspond to a point in the epigraph of interim_hedge(t, spot, future_hedge) (this is not checked).

Returns:

Portfolio that will hedge the product over the next time step.
