WASHINGTON (MarketWatch) — An organization of high-frequency traders is promoting a book it hopes will tame the scrutiny being placed on the practice.

Modern Markets Initiative, an organization made up of organizations that engage in high-frequency trading, is offering to buy readers a copy of a book written in response to Michael Lewis’s best-selling “Flash Boys: A Wall Street Revolt.”

The book’s author, Peter Kovac, a former chief operating officer at the trading firm EWT, said he was contacted by Modern Markets Initiative about promoting the book, titled “Flash Boys: Not So Fast.”

“In the book, there’s an email address and they sent an email,” he said. “Obviously I’m delighted. I just wanted to get the work out there.”

Bill Harts, CEO of Modern Markets Initiative, said that while the organization was not involved with the publication of the book, many at the organization thought it was an accurate rebuttal.

“After reading it, we thought it collected so much information that refuted the original book,” Harts said. “I think that overall what ‘Not So Fast’ does is it refutes so many of the misunderstandings.”

Kovac said he wrote the book in response to the increased scrutiny of high-frequency trading, including an FBI investigation and congressional hearings. In particular, Kovac said he wanted to refute Lewis’s claims of front-running. Lewis says firms are able effectively to pick off an order placed on one exchange and buy or sell the same security on another exchange.

“What I’m saying is Michael Lewis’s front-running scam is impossible, and I want to restore the debate,” Kovac said, adding that Lewis does not show how traders would know the quantities and price of orders. “If you don’t have the quantity and price, any front-running is impossible.”

The promotion is being advertised on the organization’s mailing list and on social-media accounts.

Harts and Kovac said that they were not sure of the specific figures but knew the book had sold in the triple digits. While an agent for Lewis declined to break out book sales, “Flash Boys” sold 135,000 copies in its first week after release.
