In the intra-day quote (CQ) file, I see quotes from
various exchanges.
It is my understanding that in order to obtain a national
best bid and offer (NBBO), one would have to determine the
most recent bids and offers from all exchanges and take the highest bid and lowest ask from among the exchanges.
Yet I also see on the file "best bid" and "best offer" fields.
Are these the NBBO's? Has someone already gone through the
above comparison?
Also, there is a National BBO Indicator field whose description
on the NYSE web site is incomprehensible. Can anyone explain
the meaning of this field?
Much thanks.
Bruce
