import java.io.*;

public class Stock {

public static void main(String a[]) throws Exception {
if (a.length!=1) {
System.out.println("usage: java Stock <symbol> ");
System.exit(0);
}

String yahoo = "finance.yahoo.com";
final int httpd = 80;
Socket sock = new Socket(yahoo, httpd);

BufferedWriter out =
new BufferedWriter( new OutputStreamWriter( sock.getOutputStream() ) );

String cmd = "GET /q?" +"s=" +a[0] +"\n";
out.write(cmd);
out.flush();

   BufferedReader in =new BufferedReader(
    new InputStreamReader( sock.getInputStream() ) );
   String s=null;
int i, j;
   // pick out the stock price from the pile of HTML
   // it抯 in bold, so get the number following "<b>"
while ( (s=in.readLine()) != null) {
if (s.length()<25) continue;
if ((i=s.indexOf(a[0].toUpperCase())) < 0) continue;
s=s.substring(i);
if ((i=s.indexOf("<b>")) < 0) continue;
j = s.indexOf("</b>");
s=s.substring(i+3,j);
System.out.println(a[0] +" is at "+s);
break;
}
}
}

Posted by: floater Posted on: 2003-09-04 01:27 You can get what you get from browsers, no more. So if there is a chinese site where you can get the quotes from, then use http connection to get the data from there.

Posted by: ftang Posted on: 2003-09-04 10:52 floater, 问一下，你们公司是用哪一家公司的MARKET DATA SERVICE的啊，我们是用的THOMASON FINANCE的叫ILX，全SOCKET的，但是我看好像REDI的也不错,http的quote不行，没法支持streamer类型的application, 我做的一个MARKET DATA SERICE，结构还不是很好，有机会请你帮忙看一下

I am not sure, although I think it's directly from exchanges since we were part of NY exchange.

I think the connection is determined by the data provider/protocol.

http is good to pass firewalls, but the only http quote I know is from yahoo and it's end-of-day. The return is just a table, easy to parse the data.

I don't have a chance to work on streamers, but I would imagine streamers, like quote.com or others are different, they are more like a broadcast thing, even a loss of a pack is tolerant sometimes. But again, no real experience. It's one of a kind application, very interesting.

Posted by: hwx Posted on: 2003-09-06 18:08 This example cannot fetch the stock price now. Yahoo just changed its html layout, so the program needs modification to get the correct stock price result.

Posted by: floater Posted on: 2003-09-06 23:30 Yea, looks like they change it. So we need to modify the url.

Use the following url, it's still working(after 5 years)


public String getURL(KeyPairs quoteParams)
    {
        String startDate = quoteParams.getStringValue(START_DATE, "");
        String endDate   = quoteParams.getStringValue(END_DATE, "");
        String stockSymbol = quoteParams.getStringValue(STOCK_SYMBOL, "");
        String scale       = quoteParams.getStringValue(TIME_INTERVAL, "d"); //default to daily

        if (!checkDateFormat(startDate) || !checkDateFormat(endDate))
        {
            return WRONG_DATE_FORMAT;
        }
        StringTokenizer ssDate = new StringTokenizer(startDate, "/");
        StringTokenizer seDate = new StringTokenizer(endDate, "/");
        String sMonth = ssDate.nextToken();
        String sDay   = ssDate.nextToken();
        String sYear  = ssDate.nextToken();
        String eMonth = seDate.nextToken();
        String eDay   = seDate.nextToken();
        String eYear  = seDate.nextToken();

        String returnURL = new String("http://chart.yahoo.com/");
        returnURL += "table.csv?&s=" + stockSymbol;
        returnURL += "&a=" + sMonth + "&b=" + sDay + "&c=" + sYear;
        returnURL += "&d=" + eMonth + "&e=" + eDay + "&f=" + eYear;
        returnURL += "&g=" + scale + "&q=q&y=0&z=" + stockSymbol + "&x=.csv";

        return returnURL;

    }
