Some even want to be called “automated trading professionals,’’ rather than high-frequency traders.
“Once the spotlight was placed on them they looked at each other, and said, ‘Us, evil? Are you kidding?’ ’’ said James J. Angel, a finance professor at Georgetown University.

At stake are billions in profits for the high-frequency traders and investor confidence in the financial system.
Critics say traders with access to the fastest machines win at the expense of ordinary investors by seizing on the best deals and turning fast profits before other traders.
They also say the lightning-fast trading strategies may be making financial markets less stable because the speed and volume of trades distort prices.

High-frequency techniques are used by Wall Street banks and hedge funds, but it is the new independent firms that account for the bulk of this new kind of activity. Most of them were founded in the past 10 to 12 years. Many are still relatively small, employing a dozen to 100 people, though some have as many as 250.
