You’re walking in Fibonacci angles

DeMark went to the Milwaukee airport to fetch him, and, after wandering around the terminal for a while, came across a man with a long white beard, who pointed at DeMark and said, “You know how I know you’re Tom DeMark? You’re walking in Fibonacci angles.” (The other doctor had told DeMark on the phone, “I’ve been married five times, I have eight children, and I take a vacation every thirteen days.”) At the meeting, the doctor took out a folder with graphs depicting the Dow Jones Industrial Average back to the inception of its precursor, in 1884.

“It embarrassed me,” DeMark recalled recently. “I thought I was going to lose my job.” He did not. The Fibonacci obsession spooked him, but it infected him all the same, because he began to see the numbers everywhere, too. Over the next decade, DeMark spent thousands of hours poring over old stock charts with a magnifying glass and a calculator, identifying patterns.
