          Have you received a reply? I haven't seen one. I thought I had seen something on "candlestick" charts, but I could not find it now. I believe there is a capability like that, but perhaps under a different name. If you would still like help from this group, please submit another post with brief but internally complete example as outlined in the posting guide (www.R-project.org/posting-guide.html) describing what you've tried and how it is inadequate. For example, if you had provided the commands you used to download WIG20.txt, that would have made it easier for me to at least get the same data. I know there are procedures in Rmetrics for downloading data, but I don't remember how to do it just now, and I don't have time at the moment to research that.

	  Good Luck,
