The problem isn't trading fast, it's trading unfairly. Not following regulations. Heaping the costs of speed on others, while reaping the benefits. We have documented hundreds of examples of clear rule violations. http://www.nanex.net/aqck/aqckIndex.html

Did you know that in 1999, during the internet bull market, the system processed just 1000 quotes/second, and today it's 1.5 million/second? Guess who pays for that? Guess who benefits? http://www.nanex.net/aqck2/3528.html

Did you know that your orders to ETrade and other retail brokers are tagged as "dumb" and sold to the highest bidder like Knight, UBS, Citadel, who then internally match your order (it never goes to the exchange, except during the flash crash). They give you the price from the slower system, but buy/sell from the faster one. The incentive to skew the two is irresistible. http://www.nanex.net/aqck2/3519.html

When you get a price-improvement of a penny on a 100 share $60,000 apple trade, they steal 99 cents - and front run some other investor, who's order is left hanging (sometimes forever). It happens in Apple more than 2,000 times a day. http://www.nanex.net/aqck2/3520.html

When you offer to buy something at a price, then yank that price before the other party can see it (speed of light), is that fair? It happens millions of times a day. http://www.nanex.net/Research/bloodbot/bloodbot.html

I could go on and on.
