How to collect stream tick stock data in IE by VBA

Dear Expert,

I get one stock software Java Applet application running in IE 7, and I know a little of
internet data extraction and Java Applet programming. Now I try to use VBA to
start my project to collect the live data in every minutes into excel file format.
In the market, there is a lot of company provide this kind of service such as the following website
http://www.analyzerxl.com/qtxl.htm, but its target data extraction website is assigned in certain or destinated website address only. It is not helping me at all. SO I try to write the VBA program instead.
First of above, I will  use nagviate to locate my website and activate the software application in
the IE instance or window and I found the difficuity to collect the data becase it is Java Script
for Java Applet  and it is not easier than collecting table or data from HTML document using
ie.document.getelementbytage or Webquery Excel table. Anyone is familar with the data
collection in IE  by VBA, please advise and help on it

Please advise

Sub loginonly()
Dim myIE As SHDocVw.InternetExplorer
Set myIE = Nothing
Set myIE = CreateObject("InternetExplorer.Application")
With myIE
 .Visible = True
.navigate "https://www.dowstock.com.hk/nfs/login.htm?lang=zh_US"
Call WAITING(myIE, 10)
.document.all("j_username").Value = "username"
.document.all("j_password").Value = "passwrod"
.document.all("login").Click
Call WAITING(myIE, 10)

.document.Links(50).Click  ' To activate the stock live Java Applet application in the same IE
Window

without seeing the source for that page i cannot be certain. but if the ticker data is shown by a java applet it's probably impossible to have ie retrieve it.

It is Java Applet application data , but why impossible , it should be okay if I can read the data in
my computer. Whether the protocol data format transmit in web by Java Applet is defined by
software company? It should be  same data format for client collect like IE could read
the data and shown it in IE windows no matter it is Java Applet or not

Please read the the source code of the web page and advise

Thanks

Yes, you are right, after talking to other experts, it is impossible to extract the Applet data except
we have the actual source code of Java Applet program from the data provider that will help to know
the data format to send to the client 's computer.

Thanks for allof you to reply
