I believe that the sum of adv, decl, and unch is the number of stocks which
have opened/traded so far in the day. Thinly traded stocks may not open
till later in the day, or may not open at all. If you chart the intraday
sum, adv+decl+unch, you will see that it starts the day near zero and rises
in a fairly smooth curve gradually approaching a maximum value of about
3400.
