Louis,
I have no problems with Yahoo EOD.  Stay away from "OB" and "PK"
(delete them from Database you got from Jim Swindle).  Then delete low
price stocks (ie below $2.00) and those with volume less than 100,000.
 Also do a periodic "Clean UP" to eliminate stocks that are no longer
active.  All databases require this even those that with high monthly
fees. Yes, there are a few (very few)that have  to be download
"current" or you can get from another source (Google or MSN).
