Yes. This doesn't happen when viewing charts in the daily time frame,only weekly and monthly. If I stay in the daily mode and click the zoom-out icon until 30 yrs of data are showing on the chart,it will display fine.But if I then switch to weekly or monthly,a lot of the volume bars will be displayed under the zero line.
Also,I don't use the volume which displays on the bottom of the price chart itself.I have vol. displayed as a seperate indicator in a different frame below the price frame.I don't know if that makes any difference or not. --- In [email protected], "wavemechanic" <[EMAIL PROTECTED]> wrote: > > Are you saying that the daily charts are OK? > > ----- Original Message ----- > From: "triangle702000" <[EMAIL PROTECTED]> > To: <[email protected]> > Sent: Saturday, April 12, 2008 1:53 PM > Subject: [amibroker] long term volume > > > > I use Yahoo EOD data,and I've downloaded historical data starting > > in > > 1970.
