Re: [amibroker] Re: Index Volume Issue - Yahoo Data

["David Fitch" <davidfitch@xxxxxxxxxxx>]

I have been using TJs suggestion to preclude large volume indexes from being cut off or at least looking that way.  But the results for some composites as well as thinly traded stocks is less than satisfying. I notice in the help files that format factors can be imbedded in data files but I'm not sure how to do this.  Here's the link

I'd like to use $VOLFACTOR 0.001, imbed in certain index files.
How do I do this?

Thanks
Dave

  Hello,

  Go to your aqh.format file (it is in "formats" subdir), edit it with Notepad and
  add
  $VOLFACTOR 0.001

  Then re-download your data.

    This is particularly peculiar, though.  A screenshot is shown at http://members.cox.net/~ramdom2/indexvol.bmp . What also confuses me is that the yahoo page showing the historical price info for this symbol has what seem to be accurate volumes but shown in amibroker is this mess of equal volume days for the most part and the exact number for the volume is repeated not only in ^GSPC but also ^IXIC,^RUT, and ^DJI.  There are no volumes greater than this number almost like whatever actually culls the data cannot handle numbers larger than this number.  Anyone with a similar problem?
