I think that the introduction of BOX will be of great benefit to public 
customers because there will be price improvement over NBBO. Also, because 
customers may participate on both sides of a PIP, there will be more 
customer-to-customer trades. I believe that all of this will make a more 
competitive, fair, accessible marketplace

I would like to express my support for BOX and would ask that the SEC 
consider approving it promptly.

Yours sincerely,
Michael Bock
