When used in Technical Analysis, the golden ratio is translated into three percentages: 38.2%, 50% and 61.8%. However, more multiples can be used when needed such as 23.6%, 161.8%, 423% and so on. The Fibonacci number series is as follows: 0,1,1,2,3,8,13,21,34,55, etc. Each number is the sum of the two previous numbers and the sequence continues infinitely. The key fibonacci ratio 61.8% is referred as golden mean.
Fibonacci retracements are considered to be hidden levels of support and resistance in the market. They are derived from the Fibonacci sequence of numbers.
