CompoundLT: Compound option valuation via lattice tree (LT) model

Description

CompoundLT prices a compound option using the binomial tree (BT) method. The inputs it takes are two OptPx objects. It pulls the S from the o2 input which should be the option with the greater time to maturity.

Usage

CompoundLT(o1 = OptPx(Opt(Style = "Compound")), o2 = OptPx(Opt(Style = "Compound")))

Arguments

o1

The OptPx object with the shorter time to maturity

o2

The OptPx object with the longer time to maturity

Value

User-supplied o1 option with fields o2 and PxLT, as the second option and calculated price, respectively.
