Can somebody explain this thing that started 3 - 4 days ago ? Many NYSE stocks do not care anymore to update Bid or Offer while printing trades lower than Bid or Higher than Ask. These stocks are not those 5 that scheduled for pilot liquid quote. Today I have seen this behavior at least 10 - 15 times in relatively low volume stocks. Is this some sort of system glitch or a green light for specialists allowing to screw everybody in order to maintain "fair" market in the interest of screwed public ?
