I've got some C#/.NET skills I want to put to use. What are some free quote servers where you could scrape OHLC stock quotes during trading hours (and I don't mean End of Day data, but the day's OHLC as it is happening this day)? Thnx
I don't mind 15 min delayed quotes. I'm not looking to scan an html file for the relevant quotes, but to actually query servers that return a CSV file or string. Does nasdaq.com really have quote servers you can query with C#?
Scraping a web site and downloading a csv file are 2 different things. No site is going to make available a csv file for free. You're going to have to scrape. Find the right page, parse the html source, extract the data you want, and save it on your system. You're reinventing the wheel. Easier to find C# library code someone has made available.
That's not true. Yahoo used to have a quote server that returned just the stock info in a short string and it was FREE. Don't know if it's still running.
Yahoo will let you download a csv file historically for quotes, which is nice, and you can get intraday quote with the usual 15min delay along a lot of other info for free in a csv file.
