# System Context (Baseline)

> For the complete documentation index, see [llms.txt](https://deploy-preview-472--lucky-concha-f3599f.netlify.app/llms.txt).

TraderX is a distributed sample trading platform composed of REST services, a pub/sub feed, a database process, and an Angular UI.

Authoritative context sources:

*   `system/architecture.md` (state-specific architecture model)
*   `system/end-to-end-flows.md` (runtime sequence flows)
*   `README.md` and `docs/README.md` (component runtime expectations)

## Baseline Runtime Shape

*   Runtime style: pre-containerized local processes started in deterministic order.
*   Communication:
    *   REST for synchronous validation/query operations
    *   Socket.IO pub/sub for trade and position events
    *   H2 database over TCP/PG/Web ports for persistence and inspection
*   UI scope for this migration baseline: Angular frontend.

## Baseline Service Set

*   `database`
*   `reference-data`
*   `trade-feed`
*   `people-service`
*   `account-service`
*   `position-service`
*   `trade-processor`
*   `trade-service`
*   `web-front-end-angular`

Ingress is part of the broader platform model but is outside the baseline uncontainerized startup flow.
