Showing charts for a ticker symbol
The normal method of showing stock information for a selected
ticker symbol is pure numerical data , now this is fine but
on a lot of financial sites they are able to display charts
as well . This would be great if you could add this to our site
well stay tuned as I am going to show you how to .
Here is the script , copy and paste this on to a new page call
it something like stockchart.php and test it out .
<%
If Request.Form("ticker") = "" Then
%>
<html><body>
<form action = <%= Request.ServerVariables("SCRIPT_NAME")
%> method = post>
Enter your ticker symbol :<input type = text name = ticker
size = 6><br>
<input type = submit value = "show chart">
</form>
</body></html>
<%
else
%>
<html>
<head>
</head>
<img border="0" src="http://ichart.yahoo.com/t?s=<%=
Request.Form("ticker")%>">
</body>
</html>
<%
End If
%>
Pretty simple idea firstly we check if the user entered anything
in the text box , if not we simply display the form again .
If a user has entered a ticker symbol we then display this on
the screen .
