IEX has used their specialized knowledge and technical expertise to present an opportunity for fair trading in the U.S. stock market, in contrast to those who have used their specialized knowledge and expertise to gain a clandestine advantage available only to a privileged few. IEX is the finest example of the market reforming itself. Please approve IEX's application to become a public exchange without delay. Sincerely, Ted Finley, retail investor
