from Zero Hedge:
While prosecuting the wrongdoers is clearly not part of the new normal (see Sokol et al.), what Nanex found this morning beggars belief – both in its method of manipulation and clarity that our regulators are clueless. As they note, the high frequency traders (HFT) are at it again. Contorting the spirit of the rules, because those who wrote the rules aren’t technically savvy. On January 4, 2013, we found another instance of HFT morphing their manipulative and illegal quote stuffing strategy in an effort to fly under the radar. Why they don’t just stop this manipulative practice altogether tells us a few things. First, this isn’t some coding error, this is sophisticated cheating. And second, because they are spending valuable programming time on this strategy, there must be some real economic advantage. Which mean a disadvantage to everyone trading against them.
