淘宝上的大智慧L2数据，月卡最便宜是8元钱，这个也可以获取BBD、DDX等数据！
Want：从顶牛股网上下载DDX数据。
1、下载历史DDE数据：获取最近120个交易日的DDE数据
#define SFURL_DNG_SINGLEL"http://www.dingniugu.com/ddedata/gegu_ddedata.php?&code="
strUrl.Format(L"%s%06d", SFURL_DNG_SINGLE, iStockCode);
OpenURL获取的数据如下：

解释：
最开始的var data=new Array(下面有20个[]字符串组，将他们分割出来。
他们依次是：收盘价、成交额、BBD金额、DDY、单数比、小单差、中单差、大单差、特大单差、涨跌幅、DDX、保留1、保留2、保留3、保留4、日期、开盘价、最高价、最低价、通吃率。
第二个var area=new Array(里面的[]对应的是出了价格、日期，其它项的Range。

只能一个Page一个Page去获取，初始根据"total":2343这个值，去计算有多少页吧，每页20项，起始Page为1。
老办法，分割，具体Item意义，见enum。
