Sigma X, der Dark Pool von Goldman Sachs

Aus einem Offenen Brief von Tyler Durden von Zerohedge.com an Senator Charles Schumer, der sich für ein Verbot von sogenannten "Flash Trades" (die Millisekundenorder beim Hochfrequenztrading) ausgesprochen hatte:

"...Senator Schumer, while Zero Hedge applauds your initiative, the truth is that the wrongdoing in the context of potential investor market abuse runs far deeper and is much more pervasive than you realize. And while one can highlight the merits of the Op-Ed published in the New York Times earlier by quant titan Paul Wilmott entitled "Hurrying Into The Next Panic" (a recommended read for you and your staff), which notes numerous frightening implications brought about by the domination of Hiqh Frequency Trading, let us stick within the context of advance looks, which is at the basis of your letter seeking the ban of Flash-like behavior.
Zero Hedge would like to highlight that while your letter to Mary Schapiro indicated your concern with such market actors as DirectEdge, BATS and Nasdaq, the truth is there are substantially larger and more dangerous "fish" on which you should focus your attention.
As a primary example, I would like to refer you to Goldman Sachs' dark pool, SIGMA X..."
