Now I am confused, seems easy to confuse me. My apologies.
I use the QT plugin for intraday. It was my understanding that with the
local data storage ticked in the 'preferences-data' then the "number of bars
to load" box does not apply. At least that is what I understand from the
help files. Maybe I am just confusing what is being discussed in the first
place.
On a side issue, it seems chuck receives my emails with a lot of extra
information and stuff added in the email text. Is this email clear from me?
Cheers,
Graham

Graham,
What Ken said is true FOR PLUGIN-DRIVEN databases.
I think you were thinking about local database with NO plugin.
Things are different when you do NOT use plugin.
(then File->Database Settings "Number of bars to load" setting does not
apply)
