Yes, I use the Open Book too. Have 4 up, one for each level two box. But regardless of volume, you still need the level two box for execution purposes.
Quote from CoralReef:
I understand all of that, but he mentioned he trades stocks that do under a mill in volume. Wouldn't one want to be looking at NYSE's open book? What good is a level2 box, you might as well be looking at a level 1 NBBO quote box and save some space.
