## Fibonacci Numbers

The Fibonacci sequence of numbers became popular in Europe thanks to an Italian mathematician Leonardo Pisano (Fibonacci), although, this sequence had been known in the East long before him. "The sequence presents a series of numbers, where each subsequent number is the sum of the previous two:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377……

The Fibonacci sequence of numbers extends to infinity and contains many unique mathematical properties.

• If any of the numbers of this sequence is divided into the previous number, then the result will be approximately 0.618 (13/21=0.619, 21/34=0.617, 34/55=0.618).
• If any of the numbers of this sequence is divided into the following number, then the result will be approximately 1.618 (21/13=1.6153, 34/21=1.6190, 55/34=1.6176).

Last sequence was used in the financial market by the famous trader Ralph Elliott. In his theory of waves, Ralph noticed that the ratio of the height of the next wave to the previous one is approximately equal to 1,618.

## How to Use Fibonacci Retracement

Practically, in any platform there is an instrument “Fibonacci Lines” with the help of which one can create correction levels - 0%, 23,6%, 38.2%, 50%, 61.8%, 76,4% and 100%. The Fibonacci lines also allow to determine the target of correction in case the trend continues – it is 161.8%, 261.8% and 423.6%. In case of an uptrend, the lines should be stretched from bottom to top, and in case of a downtrend – from top to bottom.
