# CLAUDE-factors.md — 因子引擎 + 情绪因子
|
||||
|
||||
## FactorEngine (`finance/factors/engine.py`)
|
||||
|
||||
```python
|
||||
from factors.registry import get_factor, list_factors
|
||||
from factors.engine import FactorEngine
|
||||
|
||||
fe = FactorEngine(dm, sentiment_engine=sent)
|
||||
factor_df = fe.compute("000001.SZ", [get_factor("momentum_20"), get_factor("rsi_14")])
|
||||
# → DataFrame: index=trade_date, columns=[momentum_20, rsi_14]
|
||||
cross = fe.compute_universe(factors, date="20250630", ts_codes=[...])
|
||||
```
|
||||
|
||||
因子路由:`factor.category == "sentiment"` → SentimentEngine;`isinstance(f, FUNDAMENTAL_FACTOR_TYPES)` → 注入财务数据。
|
||||
|
||||
## 因子注册表 (`finance/factors/registry.py`)
|
||||
|
||||
34 因子 / 12 分类:动量、RSI、MACD、量价、布林、ATR、均线、波动率、换手率、振幅、基本面、情绪。
|
||||
|
||||
```python
|
||||
list_factors("动量") # → ['momentum_5','momentum_10','momentum_20','momentum_60']
|
||||
get_factor("rsi_14") # → RSIFactor(period=14)
|
||||
```
|
||||
|
||||
## 技术因子 (`finance/factors/technical/`)
|
||||
|
||||
10 类。每个继承 `BaseFactor`,实现 `calculate(df) → pd.Series`。停牌跳过,新股不足 N 日返回 NaN。
|
||||
|
||||
## 基本面因子 (`finance/factors/fundamental/`)
|
||||
|
||||
- `roe.py` — ROEFactor(同花顺 `stock_financial_abstract_ths`)
|
||||
- `pe_pb.py` — PEFactor/PBFactor/EPFactor(close + 财务 EPS/BVPS map to daily)
|
||||
|
||||
## 情绪因子 (`finance/factors/sentiment/`)
|
||||
|
||||
### SentimentEngine (`sentiment_engine.py`)
|
||||
```python
|
||||
sent = SentimentEngine(dm, qwen_client=client, news_source=news_src)
|
||||
sent_df = sent.compute("000001.SZ", max_news=30)
|
||||
# → DataFrame: news_sent_5, news_conf_5, sent_delta_5
|
||||
```
|
||||
|
||||
### 新闻源 (`news_source.py`)
|
||||
三数据源聚合:AkShare `stock_news_em` + DB `xwlb_daily_ext` + MCP `trendradar-news`。
|
||||
xwlb 日期处理:DB `news_date +1day`(晚间播出→次日影响)→ `align_news_to_trading_days`。
|
||||
AkShare 限频 → 自动 fallback。LIMIT 按日期跨度动态计算。
|
||||
|
||||
### Qwen 客户端 (`qwen_client.py`)
|
||||
双后端:DashScope API + 本地 Ollama。金融情绪专家 prompt,返回 `{sentiment_score, confidence, impact_duration, key_topics}`。配置:`.env` 中的 `QWEN_API_KEY` 或 `QWEN_LOCAL_BASE_URL`。
|
||||
|
||||
### 情绪因子 (`sentiment_factor.py`)
|
||||
- `NewsSentimentFactor(window, decay)` — 时间衰减加权情绪
|
||||
- `SentimentConfidenceFactor(window)` — score × confidence 加权
|
||||
- `SentimentMomentumFactor(period)` — 情绪变化方向
