I personally feel.

If payment for order flow \"could\" be used as a vehicle by a motivated party to set aside majority of incoming orders on any stock, choose to go through that majority group and in any way dissect them BUY/SELL then decide if an order is executed on NYSE vs off exchange in any way that affect NYSE share price is used in conjunction with ability to create short position with little risk due to ability to cover FTD at Clearing House with a new exempt potentially synthetic share and fee. again avoiding nyse price influence. It would appear to this Retail investor that those abilities especially if used with any other not publicly known vehicles or ability could be used to decide what the share price is of mentioned stock with some margin of error of course.

As a retail investor, I only have basic public information and I may be very wrong about any or all above stated. I am very concerned the above is possible and in use.

Thank you for taking comments on this matter. I very much appreciate this.
