This feature of planned growth places additional constraints on the design.
Because of its power and flexibility, an object-oriented language may present itself as the ideal development environment, and an in-house trading platform is likely to be deployed using an object-oriented language. The powerful features of OOP that are attractive include polymorphism (which allows us to handle disparate products on an equal footing), encapsulation (helping us maintain modularity and maintainability), inheritance (hierarchical structuring of the design), function overloading (reuse of intuitive function names and compile-time function lookup), etc.
For all its power, OOP suffers from certain handicaps that are, in fact, the basis of some of its features. Among them are statefulness (the property that the output from a piece of code depends on the state of the program, which is inherent in constructing an object and then using its methods) and the associated lack of functional purity (the inability to guarantee that the operation in one part of the program will not have undesired, global side effects).
