Getting real-time market/stock quotes in C#/Java
提问by David Menard
I would like to make an program that acts like a big filter for stocks. To do so, I need to have real-time (or delayed) quotes from the market. I started getting stock quotes by requesting pages from yahoo, accordingand parsing the html to the ticker, and parsing the html. I was wondering how to do this requesting and parsing html. Is there some way I can request only the stock quotes and its info? I know some applications do this, and I am very curious how they do it, because requesting web pages and parsing them is very time-consuming.
我想做一个程序，就像一个大的股票过滤器。为此，我需要从市场获得实时（或延迟）报价。我开始通过从 yahoo 请求页面来获取股票报价，根据并将 html 解析为股票代码，然后解析 html。我想知道如何请求和解析 html。有什么方法可以让我只请求股票报价及其信息？我知道有些应用程序会这样做，我很好奇它们是如何做到的，因为请求网页并解析它们非常耗时。
Thanks, Dave

Parsing the output of the webpage is a chump's game. It is always changing and unless you're willing to heavily invest in some sort of very resilient parser you're going to spend your life twiddling with it. Use a web service, google offers one http://googleblog.blogspot.com/2007/01/real-time-quotes-for-free.html
解析网页的输出是一个笨蛋的游戏。它总是在变化，除非您愿意大量投资于某种非常有弹性的解析器，否则您将一生都在玩弄它。使用网络服务，谷歌提供了一个http://googleblog.blogspot.com/2007/01/real-time-quotes-for-free.html

There is actually a yahoo web service that will return CSV file of stock quotes. So no HTML parsing needed
实际上有一个雅虎 Web 服务可以返回股票报价的 CSV 文件。所以不需要 HTML 解析

In the financial services industry, most banks will have a real time feed provided by Reuters or Bloomberg, but this, obviously, will cost a lot of money. If you Google for "stock price feed" or "market data feed" you will get some options, some free, some paid for.
在金融服务行业，大多数银行都会有路透社或彭博社提供的实时信息流，但这显然会花费很多钱。如果您在 Google 上搜索“股票价格提要”或“市场数据提要”，您将获得一些选项，有些是免费的，有些是付费的。
I would also recommend using a Complex Event Processing engine such as Esperfor doing this sort of real time processing, it will be substantially easier than writing the whole application stack from scratch.
我还建议使用诸如Esper 之类的复杂事件处理引擎来进行这种实时处理，这比从头开始编写整个应用程序堆栈要容易得多。

Try to look at this channel9presentation. It is a F# introduction but from 27:00 the presenter, Luca Bolognesi, creates an application that does some of the work you are asking for (in F# but very inspirational - to me at least).
试着看看这个channel9演示。这是一个 F# 介绍，但从 27:00 开始，演示者 Luca Bolognesi 创建了一个应用程序来完成您要求的一些工作（在 F# 中但非常鼓舞人心 - 至少对我而言）。
