Abstract: This paper discusses the use of Model Driven Engineering (MDE) in finance for the purposes of defining a mathematical model and then translating it into executable code. The process involved in the formula-to-code translation provides traceable and transparent steps that are useful for educational and audit purposes. This is especially beneficial in the context of regulatory requirements, model transparency, and user understandability. The paper demonstrates the automated process constituents that transform the model firstly into MathOCL, OCL and finally into code. The stages involved in the derivation of the translation process are demonstrated by using a mathematical example of a bond and translating this into Python code.
