It would be an incredible let down for the public if the SEC does not approve IEX's application to become an exchange.

I would lose all faith in the SEC which I already blame for letting the Payment For Orderflow business model get as far as it has.

Allowing IEX to become an exchange will get the integrity of our markets going back in the right direction again.  Ultimately it will help mitigate future flash crashes as well which will only get worse and more frequent otherwise.

Very Concerned Investor,
