2007-11-29 12:06:10 / 个人分类：技术

日线文件以"代号"+"股票代码"+".day"命名，代号为"sh"或"sz"，股票代码6位，一个记录32个字节。
以深发展1997年1月2日的数据为例：
00000000h: 36 B8 30 01 72 06 00 00 86 06 00 00 60 06 00 00 ;
00000010h: 72 06 00 00 77 69 D4 4C 68 FE 66 00 74 06 00 00 ;
以下是分解
00000000h:|36 B8 30 01|72 06 00 00|86 06 00 00|60 06 00 00|;

[72 06 00 00] = 0x00000672 = 1650/100 = 16.50    开盘[unsigned long]
[86 06 00 00] = 0x00000686 = 1670/100 = 16.70    最高[unsigned long]
[60 06 00 00] = 0x00000660 = 1632/100 = 16.32    最低[unsigned long]
00000010h:|72 06 00 00|77 69 D4 4C|68 FE 66 00|74 06 00 00|;
[72 06 00 00] = 0x00000672 = 1650/100 = 16.50    收盘[unsigned long]
[77 69 D4 4C] = 0x4CD46977 = 111365048.0    成交额[float]
[68 FE 66 00] = 0x0066FE68 = 6749800        成交量[unsigned long]
[74 06 00 00] = 0x00000674 = 1652/100 = 16.52    上日收盘[unsigned long](保留)
