Why are there triggers to halt the market one way? With a ten thousand DOW 500 points is 5%. If the market wants to shoot up the regulations allow it to go to the sky, why? If they only allow the market to move so fast downward then halt the market it's really not a true free market. Let it rise and fall equally.

Please try to keep your terms consistent. "Wall Street", what is that? Is it the same as the New York Stock Exchange, a building that is located on Wall Street? "Largest one day drop in stock market history" means what--which stock market? Drop in what? You should inject "drop in the DJIA". "Drop in the DJIA" means simply an average in a small range of stocks of 30 (since 1928) large companies and the mix of companies has changed radically over the decades. We would do far better to consider the NYSE index or the S&P 500.
