# domain-model
|
|
|
|
## 목적 / 책임
|
|
|
|
ALT의 핵심 business vocabulary를 Go 타입으로 표현한다. market, instrument, price, bar, backtest run 같은 개념을 transport나 storage와 분리된 형태로 유지한다.
|
|
|
|
## 포함 경로
|
|
|
|
- `packages/domain/` - shared Go domain model module
|
|
- `packages/domain/market/` - market, venue, currency, instrument, OHLCV bar types
|
|
- `packages/domain/backtest/` - backtest run spec, run state, result types
|
|
|
|
## 제외 경로
|
|
|
|
- `packages/contracts/` - external protobuf schema representation
|
|
- `services/api/` - socket transport and API boundary
|
|
- `services/worker/` - execution and scheduled job boundary
|
|
|
|
## 주요 구성 요소
|
|
|
|
- `market.Instrument` - tradable instrument identity and provider symbol mapping
|
|
- `market.Bar` - timeframe OHLCV market data point
|
|
- `backtest.RunSpec` - strategy, market, timeframe, period inputs for a run
|
|
- `backtest.Run` - backtest lifecycle state
|
|
- `backtest.Result` - backtest financial summary
|
|
|
|
## 유지할 패턴
|
|
|
|
- Domain type names should stay concise and market-neutral unless a market-specific rule is unavoidable.
|
|
- Decimal values are represented as strings through `market.Decimal`; avoid float types for prices and quantities.
|
|
- Keep package dependencies inward: domain packages should not import API, worker, CLI, Flutter, protobuf generated code, database drivers, or proto-socket.
|
|
|
|
## 다른 도메인과의 경계
|
|
|
|
- **contracts**: domain-model owns internal Go vocabulary; contracts owns protobuf wire schema and compatibility.
|
|
- **worker**: domain-model defines the shapes; worker executes imports, normalization, and backtests.
|
|
- **api**: domain-model may be mapped to responses, but API transport details stay outside this module.
|
|
|
|
## 금지 사항
|
|
|
|
- Do not add persistence annotations, socket parser logic, or environment configuration here.
|
|
- Do not introduce generated protobuf code into this package.
|
|
- Do not use `float32` or `float64` for money, price, or quantity values.
