# 投资风险指标 (empyrical-risk-metrics)

> 计算投资组合风险指标，包括年化收益率、夏普比率、索提诺比率、最大回撤和卡玛比率，支持滚动窗口统计和 NaN 数据处理，适用于多市场数据。

## Pipeline

`data_collection -> data_storage -> factor_computation -> target_selection -> trading_execution -> visualization`

## Top Use Cases (3 total)

### Sphinx Documentation Build Configuration (`UC-101`)
Configuring Sphinx to automatically generate API documentation from docstrings and source code comments for the empyrical library
**Triggers**: sphinx configuration, documentation build, autodoc setup

### Documentation Deployment Automation (`UC-102`)
Automating the process of cleaning, building, and deploying Sphinx documentation to a hosting platform for the empyrical project
**Triggers**: documentation deployment, automated deployment, CI/CD documentation

### Advanced Sphinx Documentation Source Setup (`UC-103`)
Configuring advanced Sphinx extensions including autodoc filtering, numpydoc integration, and markdown support for comprehensive documentation generat
**Triggers**: sphinx extensions, numpydoc, autodoc filtering

**Execute trigger**: `When user intent matches intent_router.uc_entries[].positive_terms AND user uses action verb (run/execute/跑/执行/backtest/fetch/collect)`

## What I'll Ask You

- Target market: A-share (default), HK, or crypto? (US stocks in ZVT are half-baked — stockus_nasdaq_AAPL exists but coverage is thin)
- Data source / provider: eastmoney (free, no account), joinquant (account+paid), baostock (free, good history), akshare, or qmt (broker)?
- Strategy type: MACD golden-cross, MA crossover, volume breakout, fundamental screen, or custom factor?
- Time range: start_timestamp and end_timestamp for backtest period
- Target entity IDs: specific stocks (stock_sh_600000) or index components (SZ1000)?

## Semantic Locks (Fatal)

| ID | Rule | On Violation |
|---|---|---|
| `SL-01` | Execute sell orders before buy orders in every trading cycle | halt |
| `SL-02` | Trading signals MUST use next-bar execution (no look-ahead) | halt |
| `SL-03` | Entity IDs MUST follow format entity_type_exchange_code | halt |
| `SL-04` | DataFrame index MUST be MultiIndex (entity_id, timestamp) | halt |
| `SL-05` | TradingSignal MUST have EXACTLY ONE of: position_pct, order_money, order_amount | halt |
| `SL-06` | filter_result column semantics: True=BUY, False=SELL, None/NaN=NO ACTION | halt |
| `SL-07` | Transformer MUST run BEFORE Accumulator in factor pipeline | halt |
| `SL-08` | MACD parameters locked: fast=12, slow=26, signal=9 | halt |

## Top Anti-Patterns (25 total)

- **`AP-ZVT-183`**: 除权因子为 inf/NaN 时直接参与乘法导致复权静默失败
- **`AP-ZVT-179`**: 第三方数据接口超限后异常被吞噬，数据静默缺失
- **`AP-ZVT-183B`**: HFQ（后复权）与 QFQ（前复权）K 线表使用错误导致因子计算漂移
