I look forward to using the IEX exchange.

Please take up the cause of the investors that need protection from loss generated by exchanges that benefit high speed trading. Give us the option of IEX.

Please listen to the needs of the public for a an option with clear price quotes. Discern and ignore self-serving claims from companies and exchanges that want to block the IEX application.

Please consider the history and ethics of those who will run the IEX exchange. They serve (not exploit) their customer. Give us the option of IEX.

Thank you from a retired public school teacher,
William E. Pierce
