Hello,
 
Just add
$VOLFACTOR 0.001
to your aqh.format file (inside Formats subdirectory)
and you will get volume expressed in thousands of shares
(or use $VOLFACTOR 0.01 for hundreds of shares) once you re-download the history.

Subject: [amibroker] Negative volume on downloaded data from Yahoo

I just notice that the negative volume on downloaded historical data
from Yahoo! is due to overflow data in Amibroker. (It's not Yahoo!
mistake which I've been thought so far. I'm sorry Yahoo! :-) )

So I convert the negative volume data, simply by using this formula to
my favourit volume indicator:
      2*2147483647+V
and it works as I expect.

However, lately on new version of Amibroker (or Amiquote?), it looks
like that it has been 'fixed' (I'm not sure which version it has been
started), so that the volume that is greater than 2147483647 is
interpreted as 2147483647, which I don't think it is not a good idea.

Hope Amibroker will rectify this on next version.
