Good luck with that. I'm pretty sure most exchanges operate now in such a way that if the physical locations of the buildings shut down, they can continue operations remotely. In fact, most corporations plan for such a thing in this day and age, but y'all have fun creating jobs for the street sweepers and janitorial staff of NY city. I'm sure they will appreciate the OT provided by what usually are the dirty scumbag protestors who leave their crap, sometimes quite literally, behind.
