# @barfinex/types

**Shared TypeScript contracts** for the [Barfinex](https://barfinex.com) ecosystem — accounts, orders, positions, signals, connectors, and API boundaries in one place.

Every Barfinex component (Provider, Detector, Advisor, Inspector, connectors, plugins) uses these types. That means **one language** for trading entities, fewer mismatches between services, and better autocomplete and refactoring in your IDE.

---

## What it does

- **Domain models** — `Account`, `Order`, `Position`, `Candle`, `OrderBook`, `Trade`, `Signal`, and related enums (e.g. `OrderSide`, `MarketType`, `ConnectorType`).
- **Service contracts** — interfaces for detectors, advisors, inspectors, providers, and plugins so they can be composed and proxied.
- **Subscriptions & config** — types for market data subscriptions, detector config, and connector options.
- **Consistency** — same shapes in REST APIs, Redis events, and Studio; aligned with [Provider API](https://barfinex.com/docs/provider-api) and [Detector](https://barfinex.com/docs/installation-detector).
