FAQPage Schema

How do I validate trading data across multiple formats like Alpaca and yfinance?▼

Validation across trading data formats uses a unified domain model with DomainValidator to enforce consistent rules before processing trades, signals, or positions. The Skill applies SHACL-style validation rules to ensure data integrity regardless of source format.

What's the best way to ensure consistency when converting between trading data schemas?▼

A unified domain model standardizes conversion between formats by mapping entity relationships through DomainGraph and generating consistent schemas via SchemaGenerator. This eliminates format-specific inconsistencies for JSON, AVRO, SQL, and GraphQL outputs.

How do I generate API and database schemas from domain objects?▼

SchemaGenerator produces JSON, AVRO, SQL, and GraphQL schemas directly from validated domain objects. Combined with DomainValidator and DomainGraph, it ensures schema outputs reflect the same entity relationships and validation rules across all trading system components.

Can I use a domain model to enforce validation rules on trades before they're processed?▼

Yes, DomainValidator enforces validation rules on domain objects like trades before processing. The Skill integrates validation, relationships, and schema generation through a factory pattern, making consistent enforcement across all trading system components automatic.

Do I need to understand entity relationships to work with this approach?▼

Understanding entity relationships helps but isn't required to start. DomainGraph models those relationships for you; you apply DomainValidator to validate individual objects and use SchemaGenerator for outputs. The factory handles consistent object creation.
