Ex-Insider Calls High-Frequency Trading ‘Cheating’

High-frequency trading — particularly the practice of “queue-jumping” —amounts to little more than cheating, former Wall Street insider Haim Bodek said Thursday in a CNBC exclusive television interview.

“I felt, I’m playing poker with a bunch of guys, and six months after I’m losing over and over and over, they say, ‘We’re cheating. Didn’t you know? Everyone knew.’ And my problem was after that, I thought that somehow, with my firm, that because I knew how these practices work, I could somehow trade around them. And I came to the conclusion that it is actually an unbeatable system right now,” he said on “Fast Money.”

“I don’t think anybody can compete that’s outside of this particular practice, and that’s why it’s 50 to 70 percent of U.S. market because the diversity of our algorhithmic trading tradition have been annihilated by this particular practice,” he added.

Bodek, formerly of Goldman Sachs and UBS, said he had approached the Securities and Exchange Commission last year to flag what he thought were abuses by high-frequency trading mechanisms — carried out with the help of the exchanges, possibly in violation of trading regulations.

“This abuse is called ‘queue-jumping.’ It allows a sophisticated trader to get ahead of, actually, typically institutional, primarily, who are resting on the order book. It happens during a price move.

“What I argue is that this is a corruption price-time priority rules on the exchanges, and that’ll be debated in terms of whether or not that’s fair or not, but I think it’s already pretty much admitted across the board that queue-jumping does happen.”

Bodek said that he decided to come forward after he discovered the trading technique in 2009.

“I’ve been banging my head against a particular trading strategy since 2009, and at some point you just want to win and move on in some way,” he said

“This class of HFT trading is predatory, it’s disruptive to markets, and it is actually unbeatable without regulatory change.”

Both the NASDAQ and the New York Stock Exchange declined to comment when contacted by CNBC.
