I am familiar with IEX through articles in the NY Times and other news outlets. I am a supporter of what IEX stands for and would like to see their application approved by the SEC as soon as possible. The IEX would provide an option for those who want a fair and level playing field for stock exchanges. As one who will be relying on 401K s for retirement I would appreciate a straight forward honest option, the IEX. I would hope the SEC would approve this application and be an advocate for transparency and honesty in efforts to restore our faith in the financial markets.
