SEC is a joke. Look at FB. Its all a mirage and so volatile today because of HFT's, time means nothing to them, one second, one year, as long as they have the lead tick. My LULU is making money, I bet Tradeworx is not over there today, I don't see any scalping, just normal trades.
We're on the same wavelength. High-frequency trading is causing immeasurable losses to ordinary retail investors. The high volatility creates uncertainty and erodes confidence in one's ability to gauge intraday highs and lows. Additionally, the flash crashes in individual stocks are causing retail investors to such suffer horrific losses. With low volumes, it's very easy for these gangsters to cause significant moves in either direction.
