Ed, I ran into this problem with .csv import, too. I just divide the volume by 1,000 before I import it.
My .csv file breaks out up volume from down volume, but if all you want is total volume you can import it along with ^NYA historical data directly from Yahoo!, without the intermediate step of a .csv file. ^NYA, ^GSPC, ^DJI, ^DJT, and ^DJU all have the same volume(s). Here's Tomasz's post related to Yahoo! volume importing, hope it helps. S. SOLUTION TO NEGATIVE VOLUME REPORTED IN INDICES Yes it is possible to do that automatically. Open aqh.format (inside Formats directory) file with NOTEPAD and add the following line $VOLFACTOR 0.001 And re-import all downloaded data. The volume will be now reported in thousands of shares (alternatively you can use $VOLFACTOR 0.01 and then it will report volume in hundreds) Best regards, Tomasz Janeczko amibroker.com --- In [email protected], "Ed Hoopes" <[EMAIL PROTECTED]> wrote: > > I'm trying to import Yahoo! data for the symbol ^NYA - the NYSE > composite index. > > The *.csv Volume field has NYSE total volume that currently is running > around 2 billion shares/day.
