What happens if DOW drops 300 points?

I remember back in 1998 time frame when emerging market was crashing, and the market dropped 300 points , they closed the market for an hour and after it was reopened and the market dropped 500 points, they closed the market for the day. I don't even remember that it was TSE (Toronto Stock Exchange) rule or US market rule. {I was in Canada in 1998}. Now my question is that do we have such rules in the US market? It has been a long time and I have forgot.

 

Um 300 DOW pts isnt that big of a deal, where have you been?

 

I am not dreaming. I was trading at that time in Canada. But I don't remember it was only a TSE rule or .......

300 points and people yawn and go to lunch

 

and 300 pts then is more the like 500 pts today

 

I believe a 5% move down in Dow, S&P 500, or Nasdaq futures will delay the opening.

 

Thanks you answered my question.

 

THEY PUT TRADING COLLARS ON THE DOW WHEN IT DROPS 350...like in february...but it still went -520 before it bounced a bit....forget what the collar restrictions are placed but they dont ever close the market here except for 911 disasters.

 

buying opportunity

 

Is there a 0 missing in the title?
