Sure, this is a joke and not a real trading.
MMs trying to literraly "make markets" buying and selling "couple
shares" here and there... -- they pay nothing for asking and bidding,
and they don't mind losing a few hundreds $$. (I would not be surprised
if they are buying and selling to/from themselves). Even if somebody
is OK paying 9.99 for small trades it still does not make any sense
to trade couple hundres shares! - waste of time, unless you have
agenda...
At this point all squeamish longs have been most probably shaken
out... -- so no real HTOG holder wants to sell, others are sitting
on the side waiting to see PPS drop to 0.0068 before they start
nibbling...
