very odd I just kept getting a server 999 error with ^FTSE. So I tried all sorts of things. Eventually I changed the url of the server to
http://download.finance.yahoo.com/d/quotes.csv?s=^FTSE100&f=sl1d1t1c1ohgvnj1j3s1&e=.csv
and it worked?!

available symbols do , or may include any of the following:
a00,a50,b00,b20,b30,b60,c10,c60,c63,c64,c81,c82,c85,c86,g00,h00,l10,l84,l86,l90,l91,o40,o50,p20,p40,p41,p43,p44,t10,t50,t51,t53,t54,v00,z02,z08,z09

I haven’t figured out all the numbers yet, but here are a few of the letters:
a ask (a00)
b bid (b00)
c percent from previous day’s close
l last trade (l10)
t time of last trade (t10)
v day’s volume (v00)

I think downloading data for the FTSE shouldn’t be any different than the data in the sample (^GDAXI -> German Index). I tried the following in my command line and it worked right away:
curl -s -o – -N ‘http://streamerapi.finance.yahoo.com/streamer/1.0?s=^FTSE&k=l10&callback=parent.yfs_u1f&mktmcb=parent.yfs_mktmcb&gencallback=parent.yfs_gencb’

document.domain=’finance.yahoo.com’; try{parent.yfs_u1f({“^FTSE”:{l10:”4448.27″}});}catch(e){}try{parent.yfs_u1f({“^FTSE”:{l10:”4451.05″}});}catch(e){}

I’m using curl for this, just because, it is simpler to handle. A sample for curl can be found here.

Hi,
I am able to download the normal stock data. But I couldn’t able to download the FTSE data, I have been trying to solve this for age, couldn’t get it to work. I think the “^” symbol in front of FTSE mess things up. Have you got FTSE data to download? Do you have any ideas?

Thanks very much.

Hey,

basically this shouldn’t be difficult to implement in .NET. First of all use the framework given http-client and use that as input stream. In this stream you need to replace the non-JSON content with white-spaces and maybe put quotes around the API symbols (at least the C parser I use requires it). After that you can use any JSON Parser and get ordinary .NET objects from the parser.
That’s about it. If you combine these 3 steps you have your client.

Hi,

Your post seems quite impressive, I found that from Google while searching the same thing for .Net. Do you have any idea, how to implement such feature in .Net?

Your help will be highly appreciated.
