Leonardo Pisano, better known by his nickname, Fibonacci, was an Italian mathematician born in Pisa in the 12th century. He is known to have discovered the Fibonacci numbers, said to be based upon observations of the Great Pyramid of Gizeh in Egypt. Fibonacci Numbers are a sequence of numbers where each successive number is the sum of the two previous numbers.
e.g. 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, etc.
When used in technical analysis, the golden ratio is most often translated into three percentages: – 38.2%, 50%, and 61.8%. However, other multiples can be used, such as 23.6%, 161.8%, 423%, and so on. The Fibonacci sequence is applied to finance in several ways: retracements, extensions, arcs, fans, and time zones.
