Open Source C Data Modeling Software

A real-time financial derivatives calculator supporting 171+ models from QuantLib, Financial Numerical Recipes in C++ and MetaOptions. Matrices of prices are created with iterating strikes and/or months. A strike control system can produce any strike. A generalized date engine can calculate re-occuring distances to any industry used expiration into the future. Spread engine with spread views. Models Supported: Black-Scholes, Merton-73, Black-76, Roll Geske Whaley, Garman KohlHagen, Jump Diffusion, Quanto, Vasicek Bond Option, Turnbull Wakeman Asian, TimeSwitchOption, Look Barrier, Bachelier, PartialTimeBarrier, GapOption, Extreme Spread Option, Simple Chooser, ComplexChooser, PartialFixedLB, Executive, CashOrNothing, Extendible Writer, OptionsOnOptions, BAWAmericanApprox, BSAmericanApprox, AssetOrNothing, Bisection, BAWbisection, BSbisection, Gfrench, Gcarry, Swapoption, Complex Chooser, Super Share, EquityLinkedFXO, Spread Approximation, BinaryBarrier and more

LuaXLL is a lightweight Lua interpreter built into a Excel XLL. The XLL has extensions built into it which allow new Excel functions to be defined in a Lua script and exposed to the main application with the XLL marshalling data across the environments. Its primary use is for rapid modelling and development. And it could also serve as an interface to more advanced models built in C. It has built-in support for ODBC databases (via LuaSQL) and some generic modeling functions (added as I need them). The entire XLL is currently less than 600KB.
