Unfortunately I have noticed this for the past few day's
They are some pumper's/unscrupulous people placing Bid's well in excess of the previous day's close in premarket to mimic a breakout, when in fact, in the finial minutes prior to market opening at 9:30 est, the Bid's are withdrawn and I am sure a few traders (without Level II acess) fallen victim prior to the pullback. Shame on you, you know who you are, you are using the "Annon" moniker so you and your broker will not be identified , as not only is this poor trading decorum, it is also highly "ILLEGAL" , "should I see this practice again tomorrow morning, SECAR will be contacted and your anonymity will no longer be conceived once your BROKER is faces charges and/or possible suspension of trading privileges.
