Thanks for clearing the volume truncation feature of the data services.  The data disk from Metastock is not truncated that's why the problem.  Anyway I will try to delete the data and update from Reuters from scratch.

 

Thanks Larry for the help.

Hi Avnish,

 

It is standard practice in financial data reporting that volume gets truncated by two digits.  For the 30 years I have been involved in the financial markets that was the "norm" even before the PC when we had the old Quotron Machines on every brokers desk.  Over the last several years with the evolution of the PC, a growing number of programs add the two zeros to the end of volume values for you.  My educated guess is that the exchanges still report only the truncated version of volume to their data vendors to save time and space in their data feed output (they are outputting a great deal of data and any little time saving adds up).  So it is up to your data vendor or program to add the zeros or not.  In my experience, most do not because most of the financial world is used to the truncated volume (old habits die hard in the financial community).  My best advice is to just use the truncated volume.  As long as your use of volume is consistently either truncated OR not truncated your results will be exactly the same.  If the issue really bothers you or you must use both kinds of volume figures then you will have to add "x 100" when you use volume from Reuters data.  There is no fix other than that.  Actually, Reuters is stating their volume correctly according to financial industry standard practices and your other data vendor is not when they add the two zeros back on.  Sometimes in trying to help users, they actually make things more confusing (case in point).

 

If you stick to one data feed and forget the issue you will have no complications.  If you must mix the two data feeds, it may (will) get confusing.

 

Wish I could be more help.

 

Best,

Thanks Larry for your response.  I am trying to use the Reuters Datalink but the Volume data is truncated by 2 digits by Datalink.

 

For example I have Apple data downloaded with other program which shows the correct EOD volume 9,234,456.

 

When I download data from Datalink the day after it shows Volume as 62,534.  It should be 6,253,400.

 

I called Reuters help but they say it can't be adjusted by them or the Downloader and that I have to write a formula to fix this problem

 

I think there should be some fix for this.

 

Did you face this problem, if so, how did you overcome it.

 

Your help will be appreciated.

 

Thanks

 

Avnish
