We are shocked, shocked! that the nonsense shown below continues. Especially after the
recent fine a high
frequency trader received for sending less than a dozen "fake" quotes over several minutes
of time. Study the first chart - it shows over 1000 fake quotes sent in a 100 ms period
of time (1/10th of a second). Most of these fake quotes affected the NBBO.
