High Frequency Trading Doesn't Harm Investors and Other Absurdities
From Nanex:
From the 1990's through the end of 2006, electronic trading increased transparency which

The graphic in this recent
New York Times article shows the steady reduction in trading costs

The benefits, but not the higher costs, are claimed by
High Frequency Trading (HFT) proponents, who paint

The choice is not between HFT and floor trading, the choice is between HFT and transparent
electronic trading.

market transparency has a long way to go. Consider:
Amazon gives you more information about a $20 order than your broker
gives you about a $20,000 stock trade.
And if you only knew where your stock order went....MORE
