I don't know how the MM work or when they adjust their delta
hedges. I read somewhere that some square or adjust their
delta hedges at the end of the day, not that I believe it.
I would think they would have a big supercomputer plugged in
to adjust them dynamically, but it appears that's not how
it always works. Some don't care? It's a minor adjustment?
They keep things overall neutral, you know. -g-
