ores.trading.core

ores.trading.core is the primary component for trade booking and lifecycle management in ORE Studio. It implements the domain model for financial trades and instruments (rates, FX, equity, credit, scripted), the trade status FSM (see trade lifecycle for its states and transitions) enforced via ores.dq infrastructure, and a full persistence layer with temporal versioning and amendment history. Business logic is exposed as NATS message handlers in the 0x5000–0x5FFF range. The component also ships synthetic-data generators for test and development use.

• NATS request messages from peer services and UI clients (create/amend/cancel/ query operations on trades and instruments).
• PostgreSQL connections to ores_trading_* tables via the ores.dq ORM infrastructure.
• Reference-data lookups via ores.refdata.core (trade types, activity types, party roles).

• Trade and instrument records persisted to the ores_trading schema with full temporal history.
• NATS response messages returned to callers.
• Lifecycle events and activity records for P&L attribution.
