Question regarding the market disruption

[Kelvin Mace]

7. People like you and I generally don't care about

the exchanges being down an hour or two. The people who care are flash traders and other financial parasites who thrive on churning the market, conducting thousands of trades a second, and skimming fractions of a penny each time. Wall Street's major profit center is "volatility". But, when markets get closed globally, their little games can come unglued and major train wrecks will occur.

Imagine the guy on the stage spinning ten plates on poles. Now imagine that thanks to computers he can spin a thousand. But when the markets shut down, he can't get to the poles.

Now imagine there are 100,000 guys spinning a thousand plates each.

That is today's financial market.
