为什么有这个信号？
评分构成
每条进度条表示其对当前分数的贡献；权重和公式保持不变。
哪些因素限制了当前分数？
- ⚠ Cluster breadth is moderate · 1 insider(s), not 4+
- ⚠ Purchase size is modest relative to the model scale
- ⚠ Purchase activity is becoming less recent
- ⚠ Buying conviction is reduced by concurrent selling
- ✓ 角色得分高 · 买入者中职位最高的是：Director
Purchase-size comments are relative to the model scale. Average daily volume is a separate market-context diagnostic.
US-v1.2 按当前 180 天规则给合资格的股票买入打分。分数只表示研究的先后，不是收益预测或概率。回测没有显示美国分数越高、之后的表现越好。
买方广度与集中度
Roles in the peak window: Director. Concentration uses priced qualifying P lines only and does not change the saved score.
