Just out of curiousity...at what level would they close the markets, if it came to that? Thanks.

Good point - I believe they close down for an hour at -250 DJI, then again if down another 100 pts or so.

Thanks, Tuco. It doesn't look as if it's reached that level yet, although it's only be open for a few minutes, so who knows. :-)

Those are the old numbers. I'm not sure of the new ones, but I think the first pause is at about -500, there may be a freeze on automated trading at a smaller loss.
