Here is my first accounting on this thread of trading marketable on the NBBO. Purely lifting offers and hitting the bids on NBBO, in real-time. There are no production fills to the date of post #96 on this thread as I was posting hypothetical worst-case fills.
I would NEVER lift 1400-wide markets. It was a proof of concept to show that you could trade at mkt on the COB and remain profitable.
