The markets continue even if there is no trading. You can not allow trading but speculation is still going on. If we suspend Wall Street for 2 weeks...oh brother watch at that first opening bell what happens. 1929 will be peanuts compared to that. The pressure cooker has to be allowed vent steam. I have 100k sitting in a money market right now. I was not in the market and am going to time this(with help from my broker). If you have a 401k, don't look at your account...you'll be looking for a ledge.
