Fibonacci Numbers

A sequence of numbers in which each number is the sum of the two previous numbers (1, 1, 2 and so on). Some technical analysts use Fibonacci numbers to determine which securities are bullish or bearish. Some of the ways they use Fibonacci numbers are Fibonacci time zones, Fibonacci retracement, Fibonacci fans, and Fibonacci arcs.
