Front running is at most a grey area, and what is front running to you, the trader, is different than what the legally malicious definition is. Don't get me wrong: These firms do provide liquidity, which is great for anyone trading in the markets, but if you are going to try to play these firms' game of running liquidity providing strategies or even stat-arb style strategies, on their home court you just aren't going to be very effective. That is unless you are running something totally new. (Side note: I knew a guy trading MBS based off of an obscure NY state housing law. The strategy was totally unique, and ran like clock work. If you have something like that, than you could be marginally successful. He was making like 300k a year off of 60k in capital).
