"""市场异动（0x1237）异动类型解析测试（Issue #62）。

背景实测（2026-09-01 午间，全市场 SH+SZ 共 12871 条）：

|

（0x02 拉升 / 0x03 下跌 / 0x01 平稳，±0.5% 分档），v2 为竞价尾段
|
||
价格变动（相对昨收，参考时刻收敛于 09:23:30~09:24:00），v3 为竞价

- 0x16 全天分布，v2 为触发时涨跌幅：09:25 的 49 条样本与当日开盘涨幅
|
||
（open/pre_close-1）49/49 精确一致；全时段与收盘涨跌幅符号一致率
|

97%~100%。v1 为带符号强弱等级（0x01~0x03 强势、0xFD~0xFF 弱势，
|

六组 v2 区间互不重叠且单调）。

- 0x1D / 0x1E 全天分布，v1 恒为 0x00 / 0x01（方向），v2 恒正 / 恒负
