From Michael Lewis’ Flash Boys: A Wall Street Revolt... 
“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.” 

From Barron's, February 26, 2011, "Slow Go on High-Frequency Trades"
“Sal Arnuk and Joe Saluzzi…sounded a wake-up call about high- frequency trading…The regulators dismissed them…until May 6,      2010, when Saluzzi and Arnuk were vindicated by…one of the most unsettling events in stock-market history.”
