# What forex indicatrs use pi in the calculation?

Forex indicators are mathematical calculations that are used to analyze the forex market and predict future price movements. Some of these indicators use pi, which is an important mathematical constant, in their calculations. In this article, we will explore what forex indicators use pi in their calculation and how they work.

### What is Pi?

Pi is a mathematical constant that is represented by the Greek letter π. It is defined as the ratio of the circumference of a circle to its diameter. The value of pi is approximately 3.14159, although it is an irrational number that goes on infinitely without repeating.

### The use of Pi in Forex Indicators

Pi is used in various forex indicators to calculate certain values that are used to predict price movements. These indicators are based on the assumption that the forex market behaves in a cyclical manner and that certain patterns can be detected using mathematical calculations.

One of the most important forex indicators that use pi is the Fibonacci retracement. This indicator is based on the Fibonacci sequence, which is a series of numbers where each number is the sum of the two preceding numbers. The sequence starts with 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, and so on.

The Fibonacci retracement is calculated by dividing the vertical distance between a high and a low point by the key Fibonacci ratios, which are 23.6%, 38.2%, 50%, 61.8%, and 100%. These ratios are derived from the Fibonacci sequence and are used to identify potential support and resistance levels.

### – The square root of pi is used to calculate the natural logarithm of the key Fibonacci ratios.

– The natural logarithm is then multiplied by the square root of pi to get the decimal value of the key ratios.
– These decimal values are then multiplied by the vertical distance between the high and low points to get the retracement levels.

Another forex indicator that uses pi is the Gann fan. This indicator is based on the work of W.D. Gann, who was a trader and analyst in the early 20th century. The Gann fan is used to identify potential support and resistance levels based on the angle of price movements.

The Gann fan is created by drawing a series of lines that radiate from a high or low point in the chart. These lines are drawn at different angles, which are based on the value of pi. The angles used in the Gann fan are as follows:

### – 1×16: 3.576 degrees (1/64 of a circle)

The Gann fan is based on the assumption that price movements will follow these angles, which are related to the value of pi. Traders can use the Gann fan to identify potential support and resistance levels based on where the price intersects these lines.

### Conclusion

Pi is an important mathematical constant that is used in various forex indicators to predict future price movements. The Fibonacci retracement and the Gann fan are two of the most important indicators that use pi in their calculations. These indicators are based on the assumption that the forex market behaves in a cyclical manner and that certain patterns can be detected using mathematical calculations. By using these indicators, traders can identify potential support and resistance levels and make more informed trading decisions.
