@EQUITY is a set of Microsoft® Excel add-in functions that values derivative instruments used in the equity markets. Typical users are corporations, investment funds, financial institutions, insurance companies, and individual investors.
The model supports a wide range of instruments, from simple European options to more complex quanto and basket structures. @EQUITY provides users with the ability to price instruments on equities with either a constant dividend or a proportional dividend for greater flexibility. The software library version of the product (see below) is used as the basis for trading systems by some of the world's leading exchanges.
@EQUITY is written completely in C and provides extremely fast calculations. It includes Excel add-in functions (XLL files), customizable Excel templates, and documentation. When installed, @EQUITY adds functions to Excel that are used like the built-in worksheet functions, so you can customize the @EQUITY templates or create new ones.
@EQUITY is also available as the EquiLib C Library for Unix and Windows programmers who want to incorporate @EQUITY functions into custom and third-party C, C++, Visual Basic, and SQL database applications.
