"""演示：从本地通达信目录读取股本变迁数据。
|
||
|
||
股本变迁文件（gbbq）包含分红、送股、配股、扩缩股等历史记录。
|
||
数据使用 XOR 加密存储，读取时会自动解密。
|
||
|
||
XOR 加密机制:
|
||
gbbq 文件使用 1072 字节的密钥进行 XOR 加密。
|
||
文件头 4 字节为记录数量（uint32 LE，明文）。
|
||
每条记录占 29 字节（3 轮 × 8 字节 + 5 字节尾部）。
|
||
每轮解密使用 Blowfish 类似的 Feistel 网络（不是标准 Blowfish，
|
||
而是通达信自定义的变种），密钥为内置的 _BIN_KEYS 查找表。
|
||
|
||
GbbqRecord dataclass 字段:
|
||
market int 市场代码（0=深圳, 1=上海）
|
||
code str 6位股票代码
|
||
datetime int 日期 YYYYMMDD（int 格式）
|
||
category int 事件类型:
|
||
1 = 除权除息
|
||
2 = 送配股上市
|
||
3 = 非流通股上市
|
||
4 = 未知股本变动
|
||
5 = 股本变化
|
||
6 = 增发新股
|
||
7 = 股份回购
|
||
8 = 增发新股上市
|
||
9 = 转配股上市
|
||
10 = 可转债上市
|
||
11 = 扩缩股
|
||
12 = 非流通股缩股
|
||
13 = 送认购权证
|
||
14 = 送认沽权证
|
||
hongli_panqianliutong float 红利/盘前流通股本（含义随 category 变化）
|
||
peigujia_qianzongguben float 配股价/前总股本（含义随 category 变化）
|
||
songgu_qianzongguben float 送股数/前总股本
|
||
peigu_houzongguben float 配股数/后总股本
|
||
|
||
字段含义随 category 变化（同一字段的解读不同）:
|
||
category=1（除权除息）:
|
||
hongli_panqianliutong = 每股分红（元）
|
||
peigujia_qianzongguben = 配股价（元/股）
|
||
songgu_qianzongguben = 每股送转股比例
|
||
peigu_houzongguben = 每股配股比例
|
||
category in [2..10]（股本变动类）:
|
||
字段单位为万股
|
||
|
||
文件位置:
|
||
TDX_HOME/T0002/hq_cache/gbbq 或 TDX_HOME/T0002/gbbq
|
||
