  1. what exactly are they and what do they mean? i looked it up but its a bit vague.
  2. This is what happens when the NYSE invokes.

    The CME has a different set of criteria for S&P futures moves as well.

    Basically, they stop allowing automated program trading until the index moves back above the limit down territory.

    If S&P futures are down limit, they stop trading for 15 minutes, then reopen, if they are down limit again, the stop again.
