A web-reading bot made millions on the options market
<i>"The trade occurred 19 seconds before the tweet, and one second after a headline appeared on the Dow Jones Newswire."</i><p>I don't understand the mystery here.  It would be trivial to write a bot that could interpret a headline and make a trade on it in under a second, and that's without any special high-speed links.  With API documentation for a brokerage house, I could write such a bot in probably half a day.  Given the astronomical sums of money involved, I have a hard time believing that this isn't occurring on a daily basis.
