the MMs built the perfect trap with the tightening bollis. traders know that they either break up or down when they get that tight. then all they had to do was dump shares premarket to panic retail sellers and down it went.
we'll see when the bottom is in when the large block trades reappear. i had noticed lately we weren't seeing quite as many blocks, so that just means the pps had gotten above their buy zones. now it's time for the MM to take it to them. jmho.
