You are watching a stock on level2.You put in your order at a price no one else is using.Two seconds later a MM order appears in front of your order and exactly matching your size.They obviously have a puter program that does this.The government and the SEC think they can restore investor confidence while allowing this kind of chicanery?
Another thing.I think it is quite possible these crooks have hacked the ECN puters so they can read the stop loses there.
