Ask minus bid: the positive numbers represent more transactions occurring

to the tape several seconds later, thus invalidating the relationship
between
bid/ask
and
actual
trade prices.
IMPORTANT:
These are temporary, short-term stats - they cover ONLY trades displayed in
the T&S window since the opening of the window or
resetting stats.
You can reset statistics using the right-click menu: "Reset Stats"
