Quote from KINGOFSHORTS:
Retail used to pay 40 and more dollars for a single trade. Now trades are 10 bucks or even less.
Quote from clearinghouse:
I am convinced that the internalization game is so critical that no market making operation out there can sustain long term success without securing their own source of retail flow. The public exchanges are so efficient that extracting a profit is like squeezing blood out of a rock, unless you have a very unique edge or forecasting algorithm.
