Graph from DDE link in EXCEL-Help

[Johan Labuschagne <johan@xxxxxxxxxxx>]

Hi 
I am a newbie in a country where Omega does not allow their file format for
intra day (any) downloading.

As a solution I now can get a data feed with a DDE link into Excel.

The DDE link is in one exel cell and I want to draw a graph with time and
price as the two axis.

My Question:
How do you get this DDE link cell be date and time  stamped  and copy it to
another line (all the time) to build a database to plot say every 20
minutes in EXCEL??

Any VB trick, macro or anything that can help is welcome!

Thank you very much for your time!
