This article delves into the syntax, application, and nuances of using math.pow() in Pine Script.

Syntax and Overloads

The math.pow() function in Pine Script is designed to compute the power of a given base raised to a specified exponent. The function is versatile, supporting various data types as inputs and returning a float value. It is defined as follows:

math.pow(base, exponent) → const float
math.pow(base, exponent) → input float
math.pow(base, exponent) → simple float
math.pow(base, exponent) → series float


  • base (const int/float): This argument specifies the base value for the calculation. It can be a constant integer or float.
  • exponent (const int/float): This specifies the exponent to which the base is raised. Like the base, it can be a constant integer or float.


The function returns the result of raising the base to the power of the exponent. The return type varies depending on the input types but generally results in a float. If the base is a series (e.g., a time series of prices), the operation is performed element-wise for each value in the series.


To illustrate how math.pow() is used in Pine Script, let’s consider a simple example where we plot the square of the closing prices of a security:

indicator("Exponential Power Example", overlay=true)
plot(math.pow(close, 2), "Squared Close Prices")

In this example, the math.pow() function is used to square the closing price of the security (close) for each bar. The squared values are then plotted on the chart, providing a visual representation of the closing prices raised to the power of 2.


  1. Indicator Declaration: The script begins with the indicator function, naming the custom indicator “Exponential Power Example” and setting it to overlay on the main chart.
  2. Plot Function: The plot function is used to draw the squared closing prices on the chart. math.pow(close, 2) computes the square of each closing price, and “Squared Close Prices” is the label given to this plot line.

Key Features and Takeaways

  • Versatility: math.pow() can handle both constant and series data types for the base and exponent, making it suitable for a wide range of mathematical computations in technical analysis.
  • Element-wise Calculation: For series inputs, calculations are performed element-wise, allowing for dynamic analysis over time series data.
  • Floating Point Results: Regardless of the input type, the function returns a float, ensuring precision in the resulting calculations.

In summary, the math.pow() function is a powerful tool in Pine Script for performing exponential calculations. Whether you’re adjusting indicator values, applying transformations to price data, or conducting complex mathematical analyses, math.pow() provides a straightforward syntax for raising numbers to a power, enhancing the analytical capabilities of your custom scripts.
