问题描述

没有人知道谷歌或雅虎如何获取股票报价为纳斯达克或纽约证券交易所不提供任何的API？事实上，我们可以复制他们做了什么？他们使用的抓取方法本身或者更确切地说，是爬行实际上可能得​​到这样的数据实时？

does anyone know how Google or Yahoo get the stock quotes as NASDAQ or NYSE is not providing any APIs? Can we actually replicate what they do? are they using the crawl method itself or rather is crawling actually possible to get such data realtime?

推荐答案

工作@financial软件公司，我可以建议你这些服务支付。我不
知道实际数字，但我从来没有遇到过实时行情免费提供的。

Working @financial software company I can advice you that these services are paid for. I don't know actual figures, but I never encountered realtime quotes available free of charge.

要得到这些实时的反馈您正在使用的凭证与放给出;您将使用连接到提供商的服务器（超过FIX或propietary协议）连接参数。因此，有根本没有免费的来源，只支付的。

To get those real-time feeds you are given with credentials & connection parameters which you will use to connect to provider's server (over FIX or propietary protocol). So, there's simply no 'free' source, only paid ones.

报价供应商，反过来，花钱买饲料的最终来源 - 交流。您可以随时联系NYSE谈判获得报价。如果你会做，请张贴在这里议价（或者，至少，它的幅度）。

Quote providers, in turn, are paying to ultimate source of feeds -- exchanges. You can always contact NYSE to negotiate getting quotes. If you will do, please, post here negotiated price (or, at least, it's magnitude).
