Ron Insana On HFT

"The programs jump in front of customer orders and gain a trading advantage. If that is indeed what is happening, it qualifies as "front-running," an illegal practice on Wall Street. If high-frequency traders are just faster than everyone else and not illegally jumping in front of others or paying off the exchanges to get preferential trading treatment, then this new area of technology-based trading is no less legitimate than the use of the telegraph, the telephone, the ticker, computers, handheld devices or older-style "black box" or "dark pool" programs that give sophisticated traders the ability to simply trade faster."
