I use this URL http://www.nse-india.com/marketinfo/equities/cmquote_tab.jsp This URL is the URL of a frame in the page that shows the prices. the parameters you need to set are.. key=EQN symbol=$scripCode flag=0 These could either be set in the query String for a GET or as name value pairs in POST e.g. http://www.nse-india.com/marketinfo/equities/cmquote_tab.jsp?key=EQN&symbol=SBI&flag=0 Here is my fetchPrice code In java. What i am essentially doing is fetching price, removing the newlines then matching a regex to find the price. public double fetchPrice(String scripCode) throws IOException { System.out.println("Fetching price for:" + scripCode); PostMethod method = new PostMethod(url); method.addParameter(new NameValuePair("key", scripCode + "EQN")); method.addParameter(new NameValuePair("symbol", scripCode)); method.addParameter(new NameValuePair("flag", "0")); if ("true".equalsIgnoreCase(ConfigReader.getString("useproxy"))) { HostConfiguration configuration = new HostConfiguration(); configuration.setProxy("proxy.url", 80); client.executeMethod(configuration, method); }else { client.executeMethod(method); } String response = new String(method.getResponseBody()); if (response.indexOf("Last Price") != -1) { System.out.println("Last Price Exists"); response = response.substring(response.indexOf("Last Price")) .trim().replaceAll("\n", " ").toLowerCase(); } else { System.err.println("Incorrect response:" + response); } Pattern p = Pattern.compile("^last.*?(\\d+\\.\\d+).*$"); Matcher m = p.matcher(response); double returnVal = 0.0; if (m.matches()) { System.err.println("Correct Response received"); returnVal = Double.parseDouble(m.group(1)); System.out.println("Last price:" + returnVal); } method.releaseConnection(); return returnVal; } I have a list of about 120-130 stock symbols that this site uses that you will need to pass in the symbol parameter. So if anyone wants it, I could send across those symbols.
