Java Forum / General / November 2005SOAP finance requests?
I'm trying to get historic stock returns for a web-app I want to put together. Does anyone know of a source of such data? I see some SOAP sites that offer quotes but I need the previous 30 months of returns to generate my graphs. Thanks! -Robert I get mine from "finance.yahoo.com" > I'm trying to get historic stock returns for a web-app I want > to put [quoted text clipped - 5 lines] > Thanks! > -Robert What is the SOAP protocol for that?

Don't know about soap, your original request was: "I'm trying to get historic stock returns for a web-app I want to put together. Does anyone know of a source of such data?" Ok, forget the SOAP. How does your web-app retrieve the data from finance.yahoo.com? -Robert > Ok, forget the SOAP. How does your web-app retrieve the data from > finance.yahoo.com? > -Robert In a nutshell you generate a url For testing you can paste the url into your browser // coTick is the ticker symbol like "IBM" // a=month, b=day, c=year of the older date // d=month, e=day, e=year of the newer date u = "http://ichart.finance.yahoo.com/table.csv?s=" + coTick + "&a=" + ya + "&b=" + yb + "&c=" + yc + "&d=" + yd + "&e=" + ye + "&f=" + yf + "&g=" + yg; try { url = new URL(u); // then you download the url Cool. That should work. I'll get back an html that I can use to scrape out the data and apply the numbers to my formulas. -Robert > Cool. That should work.

Awesome! That's great to know! BTW: How do you come across this type of information? I didn't see anything advertised by yahoo about this? Is there a directory of these types of resources? Is there a limited number of queries that can come from an IP? Should I use an applet to keep it from looking like all the requests are coming from my web page :) ? > BTW: How do you come across this type of information?

I think you can request as often as you like, but have not tested it. >Even better, you get a text file in the csv format so you can use >split >on each line to get the data. or use a CSVReader.
