<DIV><FONT color=#000080 face="Franklin Gothic Book">I've just started 
downloading daily data from a new supplier (see sample below).</FONT></DIV>
<DIV><FONT color=#000080 face="Franklin Gothic Book">The data is fine except 
that when a security has not traded on the day and there is zero volume the 
supplier still provides the O/H/L/C which I assume&nbsp;are the most recent 
prices the security traded at. In the sample below, the security AAA hasn't 
traded since January this year. So having a data point on my chart when the 
stock has not traded to me is&nbsp;useless.</FONT></DIV>
<DIV><FONT color=#000080 face="Franklin Gothic Book">&nbsp;My previous data 
supplier only ever supplied data which <STRONG>ACTUALLY </STRONG>traded on each 
day. </FONT></DIV>

<DIV><FONT color=#000080 face="Franklin Gothic Book"><U>My question 
is:</U></FONT></DIV>
<DIV><FONT color=#000080 face="Franklin Gothic Book">Is there an easy way to 
"clean" this data and eliminate those securities from the file which have zero 
volume before I convert the file in the Downloader? I had a try in Excel without 
success and I thought maybe someone on the list might have&nbsp;a 
solution.</FONT></DIV>
