Pine Script, a powerful programming language used on TradingView, offers various functions to manipulate numerical data, including rounding. Rounding is essential for simplifying outputs, preparing data for calculations, and ensuring that price levels align with market rules. In this article, we’ll delve into the math.round function and explore how to effectively use rounding in Pine Script.

Understanding the math.round Function​

The math.round function in Pine Script is used to round numbers to the nearest integer or to a specified decimal precision. Its syntax is straightforward:

math.round(number, precision)
  • number: The value you want to round.
  • precision: An optional argument specifying the decimal places to round to. If omitted, the function rounds to the nearest integer.

Example Use Case:

//@version=5
indicator("Rounded Close Price", overlay=true)
rounded_close = math.round(close, 2)
plot(rounded_close, linewidth=3)

This script rounds the closing price to two decimal places and plots it on the chart.

Advanced Rounding Techniques​

While math.round is useful for basic rounding, Pine Script lacks a built-in function for rounding to decimal places beyond integers. However, you can create custom functions to achieve this:

Custom Rounding Functions​

  1. roundn Function: Rounds values to a specified number of decimal places.
roundn(x, n) =>
    mult = 1
    if n != 0
        for i = 1 to abs(n)
            mult := mult * 10
        n >= 0 ? round(x * mult) / mult : round(x / mult) * mult

  1. roundtick Function: Rounds values to the symbol’s minimum tick size.
roundtick(x) =>
    round(x / syminfo.mintick) * syminfo.mintick

These functions provide flexibility in handling numerical data for various trading strategies.

Conclusion​

Mastering rounding functions in Pine Script can significantly enhance your trading scripts and strategies. Whether you’re a beginner or an experienced trader, understanding how to round numbers effectively can improve your data analysis and decision-making.
