SEC is owned by Wallstreet. They regulate competition out of existence for larger investment banks and look the other way when the Big Guys are caught with their hands in the jar. It's obvious who owns who. This strikes me as a fishing expedition for Goldman to dominate the HFT world. Competition is a sin, after all. What's next? Regulators force disclosure of EVERY algorithm?? SEC already investigates funds that outperform the S&P to "prevent another Madoff". If you ask me, this is disconcerting...
