FDX (this component has restricted distribution): A simplified version of one of ART's
Finite Difference (FD) applications permitting multiple assets to be valued
and assessed for risk. This FREE version is restricted in a number
of ways, but does permit explicit and implicit calculations with
up-streaming, non-uniform grids, non-linear factors (e.g. transactions
costs), term-structure effects, etc. For example, use FD to value a
Convertible Bond with the bond component following a term-structure
model, and the equity component following a market convention model.
This component is also used in the ARTSchool Seminar: A Trader's Guide to PDE Methods
.

FuncU (Function Utility): A simplified version of one of ART's
function/formula analysers, permitting users to enter formulas in a
natural near "English language" format to produce data series
and graphics. For example, create data with different probability distributions, compare
options payouts with different distributions, compare Geometric Brownian
Motion to Arithmetic Brownian Motion, etc etc,
