Continuous Walk-Forward Optimizer Architecture with MVVM and Abstract Factories

Summary

This installment explains the internal design of an application for continuous walk-forward optimization. It uses the Model–View–ViewModel pattern to separate the graphical interface from application logic, with interfaces between the view model and model intended to keep those layers independent. UML diagrams are used to show the main objects, their relationships, and how they are created at startup.

The optimizer logic is exposed through an interface, and factory classes create particular optimizer implementations. This abstract factory approach lets the application select or replace optimization logic without binding the model to one implementation. The article also describes how optimizer settings connect to their own interface and model components. It focuses on software structure and object lifetimes, not on an optimization rule, trading strategy, or measured performance. The sequence diagram discussion is partly truncated, and the article defers the detailed optimizer algorithm and its connection to the graphics to later installments.

Key ideas

• MVVM separates the graphical interface, view model, and data model.
• Interfaces help keep the view model independent of a particular model or optimizer implementation.
• Abstract factories create optimizer instances and support changing optimization logic at runtime.
• The article uses UML class and sequence diagrams to explain object relationships and startup creation.
