Hi Dick,

The problem is that nearly 50% of the stocks I am interested into are OB or PK...

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Also do a periodic "Clean UP" to eliminate stocks that are no longer
active.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).
