1. Fibonacci series refers to such a series: 1, 1, 2, 3, 5, 8, 13, 2 1, ... This series starts from the third term, and each term is equal to the sum of the first two terms.

Second, application: it is usually not accurate in individual stocks, but usually useful in indexes. When the market is in an important key time zone, these figures can determine the specific time of change. When using Fibonacci series, we can calculate the future market from an important stage in the market, and the probability of changing direction when the market arrives is greater.

Application of Fibonacci numb in nature

Fibonacci numbers can also be found in the arrangement of leaves, branches and stems of plants. For example, choose a leaf from the branch of a tree, record it as 0, and then count the leaves in sequence (assuming there is no loss) until you reach the position directly opposite those leaves, then the number of leaves in the middle is mostly Fibonacci number.

The leaves from one position to the next are called a cycle. The number of times a leaf rotates in a cycle is also Fibonacci number. The ratio of the number of leaves to the number of leaves rotating in a period is called the leaf order ratio. Most leaf order ratios are the ratio of Fibonacci numbers.
