Show me a market where such a restrictive view is mandated and I will show you a failed market. This notion that "trading should benefit the market" is complete and total nonsense propagated by people with no understanding of liquidity. Trading is adversarial by definition. 1987 was caused by portfolio insurance from major funds, not HFT (which didn't really exist then as it does now). HFT also didn't cause the mortgage crisis. That was long term consumer financing & Gov mortgage buyers & pension investors. HFT was definitely involved in the flash crash, but what were the long term implications of that? Zero. The most recent blip was caused my dissemination of bad news via a source that had been compromised. Again, not HFT. Want to hate HFT (I do!)? Hate it because it isn't profitable (which is why I left in 2010) and because it still sucks up engineering talent like a black hole of despair. These anti-HFT articles that occasionally come out are hilarious because the money that put HFT on the public radar simply isn't there anymore. Look at GETCO. The question I have is why is the public so willing to accept disinformation? Residual banker hate?
