The traditional stock exchanges in the USA are rigged in favor of high-frequency traders. It is inexcusable that high-frequency traders are being sold advance pricing information to front-run individual investors such as myself. It is inexcusable that the markets are making more money selling rapid information to the high frequency traders, who server absolutely no economic purpose other to enrich themselves at the expense of actual investors.

I hope that the SEC will make sure that the IEX has no regulatory obstacles to ending the present unacceptable situation.

Personally, I would prefer that my trades be executed on that IEX. The SEC has not ensured that the stock exchanges are a fair market, and it's about time that the IEX is allowed to do so.
