This capability is especially valuable for traders who rely on volatility-based signals or want to add an extra layer of analysis to their existing setups.

In the following sections, we will explore the fundamentals of ATR, how it is calculated, and the essential steps to plot it using Pine Script. Whether you’re a beginner eager to enhance your scripting skills or an experienced trader looking to customize your tools, mastering ATR plotting will empower you to make smarter, data-driven trading decisions.

Calculating the Average True Range (ATR) in Pine Script

The Average True Range (ATR) is a popular technical indicator used to measure market volatility. In Pine Script, ATR can be calculated using the built-in `ta.atr()` function, which simplifies the process and ensures accuracy. However, understanding the underlying calculation is essential for customization or troubleshooting.

The True Range (TR) is the greatest of the following three values for each bar:

Current high minus current low
Absolute value of the current high minus the previous close
Absolute value of the current low minus the previous close

The ATR is then computed as the moving average of the True Range over a specified period, typically 14 bars.

Here is a basic example of how to calculate ATR manually and using the built-in function in Pine Script:

“`pinescript
//@version=5
indicator(“ATR Calculation Example”)

// Calculate True Range manually
tr = math.max(high – low, math.max(math.abs(high – close[1]), math.abs(low – close[1])))

// Calculate ATR manually using a simple moving average
atr_manual = ta.sma(tr, 14)

// Calculate ATR using built-in function
atr_builtin = ta.atr(14)

// Plot both ATR lines for comparison
plot(atr_manual, color=color.blue, title=”Manual ATR”)
plot(atr_builtin, color=color.orange, title=”Built-in ATR”)
“`

This script calculates the True Range manually, then applies a simple moving average to compute the ATR, and finally overlays the built-in ATR for reference. The two should closely match, though the built-in version uses Wilder’s smoothing method by default.

Plotting the ATR with Custom Styling

Visualizing the ATR on a chart helps traders quickly assess volatility changes. Pine Script allows comprehensive customization of plot appearance, including line color, width, style, and transparency.

To enhance readability and integrate ATR into your trading strategy, consider these styling options:

Line color: Use contrasting colors to distinguish ATR from other indicators.
Line width: Thicker lines improve visibility on high-resolution displays.
Line style: Dotted or dashed lines can differentiate ATR from price data.
Transparency: Adjust opacity to prevent cluttering the chart.

Example of plotting ATR with custom styles:

“`pinescript
//@version=5
indicator(“Styled ATR Plot”)

atrValue = ta.atr(14)

plot(atrValue, title=”ATR”, color=color.new(color.red, 0), linewidth=2, style=plot.style_line)
“`

You can further customize the plot by adding conditions to change colors dynamically based on ATR values, such as highlighting periods of high volatility.

Using ATR for Dynamic Stop Loss and Take Profit Levels

Traders often use ATR as a volatility-based measure to set dynamic stop loss and take profit levels. This approach adapts the risk management parameters to market conditions rather than using fixed price points.

The general formula for ATR-based stops:

Stop Loss = Entry Price ± (ATR × Multiplier)
Take Profit = Entry Price ± (ATR × Multiplier)

Where the multiplier is a user-defined factor reflecting risk tolerance.

In Pine Script, you can implement this as follows:

“`pinescript
//@version=5
indicator(“ATR-based Stops”)

atrLength = input.int(14, “ATR Length”)
atrMultiplier = input.float(1.5, “ATR Multiplier”)

atrValue = ta.atr(atrLength)

longEntry = ta.crossover(ta.sma(close, 10), ta.sma(close, 30))
shortEntry = ta.crossunder(ta.sma(close, 10), ta.sma(close, 30))

var float longStop = na
var float shortStop = na

if (longEntry)
longStop := close – (atrValue * atrMultiplier)

if (shortEntry)
shortStop := close + (atrValue * atrMultiplier)

plot(longStop, color=color.green, title=”Long Stop Loss”, linewidth=2)
plot(shortStop, color=color.red, title=”Short Stop Loss”, linewidth=2)
“`

This example demonstrates setting stop loss levels dynamically when a crossover or crossunder occurs, using ATR to adjust the stop distance.

Comparing ATR Calculation Methods

There are multiple ways to calculate and smooth the ATR, each with different implications for responsiveness and noise reduction. The most common methods include:

Wilder’s Moving Average (WMA): The default method in Pine Script’s `ta.atr()`, which uses an exponential smoothing technique.
Simple Moving Average (SMA): A straightforward average which may be less responsive.
Exponential Moving Average (EMA): Gives more weight to recent values, increasing sensitivity.

The table below compares these methods:

Method	Smoothing Type	Responsiveness	Typical Use
Wilder’s Moving Average	Exponential smoothing with specific weighting	Moderate	Standard ATR calculation, commonly used in volatility indicators
Simple Moving Average (SMA)	Equal weighting	Less responsive	Basic smoothing, useful for steady trends
Exponential Moving Average (EMA)	Exponential weighting	More responsive	Captures recent volatility spikes faster

You can implement these variations in Pine Script by replacing the smoothing function applied to the True Range values.

To enhance ATR plots, conditional coloring can visually indicate rising or falling

Implementing and Plotting ATR in Pine Script

The Average True Range (ATR) is a popular technical indicator used to measure market volatility. In Pine Script, ATR can be computed easily using built-in functions, and the resulting values can be plotted on the chart for real-time analysis. Below is a detailed explanation and example on how to plot ATR in Pine Script.

The core steps to plot ATR involve:

Calculating the ATR value for a specified period.
Customizing the ATR plot appearance such as color, line width, and style.
Optionally adding the ATR plot to a separate pane or the main chart.

Using Built-in ATR Function

Pine Script provides the ta.atr() function to calculate ATR values directly. This function simplifies the process and ensures accuracy.

Parameter	Description	Type	Default
length	Number of bars used to calculate the ATR	integer	14

Example code snippet to calculate and plot ATR with a 14-bar period:

“`pinescript
//@version=5
indicator(“Average True Range (ATR)”, overlay=)
atrLength = input.int(14, minval=1, title=”ATR Length”)
atrValue = ta.atr(atrLength)
plot(atrValue, title=”ATR”, color=color.orange, linewidth=2)
“`

indicator() defines the script’s metadata.
input.int() allows the user to modify the ATR period dynamically.
ta.atr() calculates the ATR based on the specified length.
plot() renders the ATR line on a separate pane below the price chart.

Customizing the ATR Plot Appearance

Adjusting visual properties enhances readability and helps emphasize important volatility changes. Common customizations include:

Line Color: Use contrasting colors like orange or blue to distinguish the ATR line.
Line Width: Increase line thickness for better visibility.
Plot Style: Choose between line, histogram, or area plots depending on preference.
Background Highlight: Add background color changes to signal high or low volatility zones.

Example of a customized ATR plot with background color indicating high volatility:

“`pinescript
//@version=5
indicator(“ATR with Volatility Highlight”, overlay=)
atrLen = input.int(14, title=”ATR Period”)
atr = ta.atr(atrLen)
highVolThreshold = input.float(atrLen * 0.5, title=”High Volatility Threshold”)

plot(atr, title=”ATR”, color=color.new(color.blue, 0), linewidth=2)

bgcolor(atr > highVolThreshold ? color.new(color.red, 90) : na)
“`

Plotting ATR on the Main Chart

By default, ATR is plotted in its own pane. However, users may prefer to overlay it on the price chart for direct comparison with price action.

To plot ATR on the main chart, set the overlay parameter in the indicator() function to true. Since ATR values are volatility measures and typically smaller than price levels, you may need to scale or normalize the ATR for meaningful visualization.

Example code snippet that plots ATR on the price chart scaled by a multiplier:

“`pinescript
//@version=5
indicator(“ATR Overlay on Price”, overlay=true)
atrPeriod = input.int(14, title=”ATR Period”)
scaleFactor = input.float(1.0, title=”Scale Factor”)

atrValue = ta.atr(atrPeriod)
scaledATR = atrValue * scaleFactor

plot(scaledATR, title=”Scaled ATR”, color=color.purple, linewidth=2)
“`

overlay=true ensures the ATR is drawn over the price chart.
scaleFactor lets the user adjust the ATR magnitude to align visually with price levels.
This approach is useful when combining ATR with other price-related indicators.
