Leonardo Pisano, also called Fibonacci (Fibonacci stands for filius Bonacii) was born in Pisa during 1170. His father, Guglielmo dei Bonacci, a rich Pisan merchant and a representative of the merchants of the Republic of Pisa present in the area of Bugia in Cabilia (in modern north-eastern Algeria), after 1192, he took his son with him, because he wanted Leonardo to become a merchant like him.

So the solution to this problem is the famous “Fibonacci sequence” which is: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89… a sequence of numbers where each of them is the sum of the previous two numbers.

Let’s know what a fibonacci number is. A Fibonacci number is known to be a series of numbers where each of the Fibonacci numbers is found by adding the two preceding numbers. It also means that the next number in the series is the addition of the two previous numbers. Let us take the first two numbers in the series as 0 and 1. So by adding 0 and 1, we will get the third number as 1, and by adding the second and the third number which is 1 and 1, we get the fourth number to be 2, and likely, the process goes on and on.

So, we get the Fibonacci series as 0, 1, 1, 2, 3, 5, 8, ……. Therefore, the obtained series is called to be the Fibonacci number series. Now we know what the fibonacci number is.

We will discuss what is the Fibonacci series. The list of the numbers of Fibonacci Sequence is given below. This list is created by using the Fibonacci formula, which is also mentioned in the above definition.

The Fibonacci sequence is a set of the numbers that starts with a one or a zero, which are followed by a one, and then proceeds based on the rule that each of the numbers (called a Fibonacci number) equals to the sum of the preceding two numbers. If the Fibonacci sequence is put up as F (n), where n is the first term in the sequence, so the following equation obtains for n = 0, where the first two terms are put up as 0 and 1 by the convention:

F (0) equals 0, 1, 1, 2, 3, 5, 8, 13, 21, 34 ...

In some of the texts, it is mandatory to use n = 1. So, the first two terms are defined as 1 and 1 by default, and we see:

F (1) equals 1, 1, 2, 3, 5, 8, 13, 21, 34 …

The sequence of the Fibonacci numbers can be written as:

Fn = Fn-1 + Fn-2

Where Fn is the nth term or the number

Fn-1 is the (n-1)th term

Fn-2 is the (n-2)th term

From the equation above, we can also write up the definition as the next number in the sequence, and is the sum of the previous two numbers which are present in the sequence, starting from 0 and 1. So, let's make a table to find the next term of the Fibonacci sequence, using the above Fibonacci formula.

In the above table, we can see that the numbers in each of the columns are relational, and also diagonally the numbers are the same in all three columns.

The following points below are the properties for the Fibonacci numbers:

In the Fibonacci series, let us take any of the three consecutive numbers and add those numbers. When we divide the result by 2, we will get the three numbers. Example, let’s take 3 consecutive numbers like 1, 2, 3. when we add these numbers that are 1+ 2+ 3 = 6. When 6 is divided by 2, the result will be 3.

Take four of the consecutive numbers other than “0” in the Fibonacci series. Then multiply the outer number and also then multiply the inner number. When we subtract these numbers, we will get the difference “1”. For example, if we take 4 consecutive numbers like 2, 3, 5, 8. Multiply the outer numbers (i.e) 2(8) and then multiply the inner number which is 3(5). Now we subtract these two numbers 16-15 =1. So, the difference is 1.

Applications for the Fibonacci numbers will also include the computer algorithms like the Fibonacci search technique and then the Fibonacci heap data structure, and the graphs called as Fibonacci cubes which are used for interconnecting the parallel and distributed systems.

The usage of the Fibonacci studies is very subjective since the trader has to use the highs and the lows of their choice. Whichever highs and lows that are chosen will also affect the results the trader gets.

Another argument against the Fibonacci number trading methods is that there are also so many of these levels that the market has to bounce or to change the direction near one of them, making the indicator look significantly in hindsight. The problem is that it is very difficult to know which of the numbers or the level will be important in real-time or in the future.

FAQ (Frequently Asked Questions)

1. Is 613 a Fibonacci number?

Long Form Fibonacci Test shows that 613 is NOT a Fibonacci number because the sum for the last equation is way larger than the number 613 and the sum of the equation before it is very smaller than the number 613. It is just one way to find a Fibonacci number and it is also arguably the easiest to understand.

2. What are the first 10 Fibonacci numbers?

The first 10 Fibonacci numbers are as follows 1, 1, 2, 3, 5, 8, 13, 21, 34, 55.

3. What is the largest Fibonacci number?

2222

Fib(2222) (with 465 digits) is also the largest known Fibonacci number and with this property. There are also no others with N<5000, and it looks likely that Fib(2222) is actually the largest one. But, no proof exists for this"

4. What are the Fibonacci numbers used for?

The numbers also reflect how far the price can go following the other price move. Example, if a stock moves from ＄1 to ＄2, then the Fibonacci numbers can also be applied to that. A drop to ＄1.76 is also a 23.6% retracement for the ＄1 price move. Two of the common Fibonacci tools are the retracements and extensions.
