Thanks a lot. Graham. Your code does work!!
The reason I use a mized database is that I have 5 yr of EOD data but
only one week of 5 min data. When I want to compare volume vs 3 mon
avg volume, i need the EOD data.
Two questions:
1) Can I work in two databases? For example, in 5-min database, call
the avg volume in EOD database???
2) where can i buy the database that have 5-min data for 3 yrs or
longer?
