Modeling Financial Relationships with Category Theory Concepts in MQL5
Summary
The article continues an introduction to representing domains and relationships with category theory concepts in MQL5. It discusses identity and composition, uses everyday examples to illustrate mappings, and presents template-based classes for domains and morphisms. It also introduces ontology logs as a way to organize information about a process, with trade execution in forex offered as an example of a process that could be represented in structured form.
The stated motivation is to make relationships among financial concepts easier to represent and compare, potentially helping identify correspondences between apparently different systems. The article includes code-oriented demonstrations, but the supplied text is incomplete and provides no market study, trading method, or empirical evidence that the framework improves decisions or results. Some explanations of isomorphism and morphisms are mathematically imprecise, so readers should consult formal category theory references before relying on the definitions. The material is best treated as an exploratory programming illustration rather than a validated analytical tool.
Key ideas
- The article represents domains and mappings between them using category theory terminology and MQL5 templates.
- Identity and composition are presented as core properties for defining categories.
- Ontology logs are proposed as a structured way to describe processes such as forex trade execution.
- The examples suggest organizing relationships, but they do not demonstrate predictive or trading performance.
- Some mathematical explanations are imprecise and should be checked against formal references.
