Hi - You are correct, and the workaround is that Volume needs to be divided by 1000 (for example ) to make it smaller. I don't use Yahoo data but there is a keyword $VOLFACTOR that works with ( I think ) ASCII importer to accomplish this.. It is briefly mentioned in the user guide, try doing a search on on that term.
