In addition to having said many things about HFT in general in the last year, over the past 12 months Zero Hedge has focused a lot of attention specifically on Goldman's dominance of the NYSE's Program Trading platform, where in addition to recent entrant GETCO, it has been to date an explicit monopolist of the so-called Supplementary Liquidity Provider program, a role which affords the company greater liquidity rebates for, well providing liquidity (more on this below), and generating who knows what other possible front market-looking, flow-prop integration (presumably legal) benefits. Yesterday, Goldman's SLP function was non-existent. One wonders - was the Goldman SLP team in fact liquidity taking, or to put it bluntly, among the main reasons for the market collapse. We are confident the SEC will aggressively pursue this line of questioning as they attempt to justify their $1 billion porn download budget. We are also confident, that should the SEC truly take its role of protectors of investor interest seriously for once, it will uncover such criminality and corruption at the level of trading integration of open exchange and ATS venues (and the "but it's so complicated - let's just leave it untouched because nobody understands it" excuse is not flying any more), that it will make Goldman's CDO criminal and civil case seems like a dimestore misdemeanor. We have written about 1,000 posts about this. Readers are welcome to go back through our archives and acquaint themselves with the NYSE's SLP program, with Goldman's domination of program trading, with Goldman's domination of dark trading venues via the Sigma X suite, with Goldman's domination of flow trading via Redi X, and with Goldman's domination of virtually every vertical of the capital markets, which would be terrific if monopolies were encouraged in the US. Alas (last time we checked with the DOJ), they are not. Which is why we ask, for the nth time, when will the anti-trust division of the DOJ finally dismantle the biggest market monopolist in the history of capital markets.
