"""催化事件、事件日字段与定价状态的离线单测（不连库）。2026-09-08《量价研判链吸收方案》3.4。
|
||
|
||
钉住四件事：
|
||
一，四类券商正向事件的定义各自成立：深度覆盖看前 365 天有无覆盖与评级；上调预测看同机构同预测期
|
||
180 天内的上一篇；超预期看标题；同一天多篇合并成一条并标复合；窗口之外的不算。
|
||
二，事件日字段：事件前涨幅、跳空、日内收益、收盘位置、量比、涨停各自算对；行情不够时留空不硬算；
|
||
没有事件的票按数据日算。
|
||
三，定价状态四情形的规则一次定死（台账 046），四种各有样例，缺字段时写明缺什么。
|
||
四，卡上的文字与表格短写法。
|
||
|
||
开发机没有 pandas 与数据库驱动时只给缺席的模块装最小桩（与 test_valuation.py 同一约定）。
|
||
跑法：python3 test_events_pricing.py 或 pytest test_events_pricing.py
