需要注意的这个只是获取单只股票

代码的用处，通过这个代码有炒股的朋友就可以写出简单的自动止损和按一定价格入场的程序了。（国内正规券商不支持这种功能，可能是为了防止一些东西。）

我们先来看一下股票信息的类

   3：”26.91″，当前价格；//时间结束后也就是收盘价了
   4：”27.55″，今日最高价；
   5：”26.20″，今日最低价；
   6：”26.91″，竞买价，即“买一”报价；
   7：”26.92″，竞卖价，即“卖一”报价；
   8：”22114263″，成交的股票数，由于股票交易以一百股为基本单位，所以在使用时，通常把该值除以一百；
   9：”589824680″，成交金额，单位为“元”，为了一目了然，通常以“万元”为成交金额的单位，所以通常把该值除以一万；
   10：”4695″，“买一”申请4695股，即47手；
   11：”26.91″，“买一”报价；
   12：”57590″，“买二”
   13：”26.90″，“买二”

   20：”3100″，“卖一”申报3100股，即31手；
   21：”26.92″，“卖一”报价
   (22, 23), (24, 25), (26,27), (28, 29)分别为“卖二”至“卖四的情况”
