From the Ted Talk by Kevin Slavin: How algorithms shape our world

Unscramble the Blue Letters


And he said, "It's funny you ask that, because it's actually called black box trading. And it's also sometimes called algo tarding, algorithmic trading." And algorithmic trading evolved in part because institutional traders have the same problems that the United States Air Force had, which is that they're mnvoig these positions — whether it's Proctor & Gamble or Accenture, whatever — they're moving a million srhaes of something through the market. And if they do that all at once, it's like playing poker and going all in right away. You just tip your hand. And so they have to find a way — and they use algorithms to do this — to break up that big thing into a million little transactions. And the magic and the horror of that is that the same math that you use to break up the big thing into a million little things can be used to find a milloin little things and sew them back together and figure out what's actually happening in the mkreat.
