Some of the people who oppose the FRR are trying to create a barrier to entry (and reduce competition) by requiring that people either 1) spend a lot of time manually entering offers, or 2) learn how to program a bot.
Excuse me, by your logic - your discount brokerage is creating barrier to entry by requiring that people to 1) enter their order from a computer or 2) enter their order via a mobile app or 3) call them to enter an ordrer
come on, something is just so fundamental - ie. entering your order, that you can actually complain about!
