View source: R/QFRM.R

Description

Compute option price via binomial option pricing model (recombining symmetric binomial tree). If no tree requested for European option, vectorized algorithm is used.

Usage

1
BOPM(o = OptPx(), IncBT = TRUE)

Arguments

o

An OptPx object

IncBT

Values TRUE or FALSE indicating whether to include a list of all option tree values (underlying and derivative prices) in the returned OptPx object.

Value

An original OptPx object with PxBT field as the binomial-tree-based price of an option and (an optional) the fullly-generated binomial tree in BT field.

Each matrix is a set of possible i outcomes at time step i columns: (underlying prices, option prices)
