Just wanted to say that 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 the effective spread you pay, and with that our total transaction cost for trading, diminish. For these reasons I support BOX. Thank you for your attention and consideration. Best Regards, Leland Stevenson
