The primary function of what they're wanting is to fleece the American public by frontrunning trades. The high frequency traders have been doing this for years by buying in front of know orders and reselling for as little as a fraction of a cent and making something on every order. It's been a well known fact that the distance from the exchange over the landline has a latentcy that puts one group of traders behind another in doing this illegal, but largely untraceable, practice. Do it enough times a day, it's big money, especially by using automated programs. Pretty much a no lose deal for the dealers, with the retail customers paying for it in (admitedly small) higher prices.
I'd attack it on that basis. It's not good for the average American investor.
Saying this from my experience as a general securities principal.
