为什么没有活跃信号？
评分构成
活跃窗口内没有合资格买入，因此不计算分数。缺失的输入不会被当作零分或看空信号。
为什么没有分数？
- 没有合资格公开市场买入可提供聚集度、规模、角色、近期性或确信度输入。
- 卖出及其他 Form 4 活动继续作为背景显示，不会形成负分。
卖出和其他 Form 4 活动会单独显示，不会形成负面买入信号。没有买入不会被评分为看空。
买方广度与集中度
Roles in the peak window: CEO and Board Member. Concentration uses priced qualifying P lines only and does not change the saved score.
