“Arnuk and Saluzzi, the principals of Themis Trading, have done more than anyone to explain and publicize the predation in the new stock market. They deserve more lines in this book than they receive but have written their own book on the subject, Broken Markets.”

“When the last history of high-frequency trading is written, Hunsader, like Joe Saluzzi and Sal Arnuk of Themis Trading, deserves a prominent place in it.”

-MICHAEL LEWIS, Flash Boys

BOSTON GLOBE: "Did you read something for Flash Boys you would recommend?"

LEWIS: "Scott Patterson’s Dark Pools, which overlaps with my own book some. What he does really well is tell the early history of automated electronic trading. I’d also recommend Broken Markets by Sal Arnuk and Joe Saluzzi and the 1923 novel Reminiscences of a Stock Operator by Edwin Lefèvre."
