tell me about it..you don't need some nanex feed to spot those fuckers. it's all over the place and been like this for a very long time.
looks like SEC is care less about it..same for market centers. cause they been paid for it. they should implement something similar to what IB have-calculate fill ratio. orders placed vs orders executed. and penalize or ban those fuckers,who place a shit load of orders without any intention to buy or sell anything.
