Question

我正在尝试使用YQL从Yahoo Finance检索选项数据。非常奇怪的问题是，我可以为其他符号下载所需的选项数据，例如AAPL（Apple）和MSFT（Microsoft），但不适用于GOOG（Google）。

这是我的查询和结果。显然，我可以检索AAPL和MSFT的数据，但很遗憾。这不仅发生在yahoo.finance.option_contracts上，还发生在所有其他与选项相关的表中，包括yahoo.finance.options。我很确定这不是与查询限制有关的事情，因为下面显示的查询预计只能检索不到10个结果。

select * from yahoo.finance.option_contracts where symbol in ( 'GOOG', 'AAPL', 'MSFT')

{

      "2014-10",

      "2016-01"
     ]
    },
    {
     "symbol": "MSFT",
     "contract": [
      "2014-03",

      "2015-01",
      "2016-01"
     ]
    }
   ]
  }
 }
}

总之，每当我尝试检索GOOG的期权数据时，我只会得到“读取超时”错误的空结果。对于其他选项符号，例如AAPL和MSFT，我得到了我想要的东西。

任何人都知道为什么会这样？

这必须与谷歌公司在 TWO 贴纸下交易（见http://finance.yahoo.com/news/google-trades-under-2-tickers-225300863.html）：GOOG和GOOGL。

YQL不承认GOOG，但会接受新的代码 GOOGL 。我怀疑YQL查询错误出乎意料地得到两个代码而不是一个寻找只是一个。

如果您在Yahoo！Finance上请求Google报价，则可以。

选项符号'GOOG'在YQL中不起作用
