Implementing Domain-Driven Design with Spring and vFabric
summary
Reference trading app NanoTrader (now Spring Trader) shows Domain-Driven Design applied with Spring MVC, Spring Integration, RabbitMQ, Hibernate over SQLFire/GemFire and Postgres to add an algorithmic trading core that calculates a VWAP analytic, aggregates quotes into bars every ~100 quotes or 2s across 100 symbols, and issues 100-share slice orders when price < VWAP for inbound orders ≥500 shares. Code is refactored into aggregates, immutable value objects (Money, QuoteBar), business IDs and published order placed event / order-filled events enabling eventual consistency — the demo executes real slices successfully.
