divergence_detector.py — 跨市场背离监测器（no_agent）
|
|
|
|
每30分钟检测：
|
|
1. 科创50 vs 恒指 → 科技股超买/超卖信号
|
|
2. A/H 隐含溢价 → 内外资分歧度
|
|
3. 上证50 vs 创业板 → 风格轮动信号
|
|
4. 恒指 vs 国企指数 → 离岸市场情绪
|
|
5. 指数连涨/连跌天数 → 趋势延续/衰竭
|
|
|
|
输出：
|
|
- HIGH/medium divergence → 写入 signal_news (source=divergence_watch)
|
|
- 状态文件 macro_divergence_state.json
|
|
- no_agent: 有信号才出声
