Of course they disagree with the ruling. The whole industry is set up to front run. If others are doing it each day (alot bigger than them) then why are they being singled out? lol. What a cess-pit. The more regulation the SEC apply, the easier the big traders find a loop-hole. If you are going to front run, you have to find out the intent of the big players who want to fill orders for as little cost to themselves as possible. Order baiting and spoofing is rampant. It's a riskless trade for them. No way is that ever going to stop.
