ores.trading.service

ores.trading.service is the NATS service entrypoint for the trading domain. It is a thin wiring layer: it reads configuration, opens database and NATS connections, registers all message handlers from ores.trading.core, and runs the event loop. All business logic lives in ores.trading.core; this component is responsible only for bootstrap, dependency injection, and graceful shutdown.

• Configuration file: NATS server URL, PostgreSQL connection string, logging settings, and environment name.
• NATS request messages from UI clients and peer services on the ores.trading.* subject hierarchy.

• A running NATS service handling all trading operations (0x5000–0x5FFF range).
• NATS response messages returned to callers.
• Structured logs to the configured log sink via ores.logging.

• src/main.cpp — process entry point; initialises logging and starts the application.
• src/application.cpp — bootstraps all subsystems and wires dependencies.
• src/host.cpp — manages the NATS connection and handler registration loop.
• src/config/ — configuration parsing and validation.

• ores.trading.core — all NATS handlers, repositories, and domain services.
• ores.trading.api — shared protocol types.
• ores.logging — structured logging infrastructure.
• nats.c — NATS client for connection management.

What the shared profile cannot know, declared here rather than hand-edited into the generated build file. Each block is spliced into its generated file after the profile's baseline.

The options this service takes beyond logging, NATS and the database. Codegen writes the member, its wire field, its command-line declaration and its assignment from each entry.

• ores.trading.core — all business logic for the trading domain.
