What is Average True Range (ATR)?​

The Best Pine Script Generator

ATR is a measure of volatility that was developed by J. Welles Wilder Jr. It reflects the degree of price movement over a specified period, typically 14 days. Unlike other indicators that may focus solely on price direction, ATR provides insights into market volatility, which can be crucial for setting stop-loss orders and determining position sizing.

How ATR is Calculated​

The ATR is derived from the True Range (TR), which is calculated using the following formula:

Once the True Range values are calculated, the ATR is then computed as an exponential moving average of these values over a specified length.

Pine Script Syntax for ATR​

In Pine Script, you can easily access the ATR function using ta.atr(). The basic syntax is as follows:

ta.atr(length) → series float
  • length: This argument specifies the number of bars back to calculate the ATR.

Example of Using ATR in Pine Script​

Here’s a simple example demonstrating how to implement the ATR in your script:

length = input(14, title="ATR Length")
atrValue = ta.atr(length)
plot(atrValue, color=color.blue, title="ATR")

In this example:

  • We define an indicator named "Average True Range".
  • The user can set the length of the ATR calculation through an input field.
  • The calculated ATR value is plotted on the chart.

Practical Applications of ATR​

The ATR can be utilized in various trading strategies:

  • Volatility-Based Stop Losses: Traders often set stop losses at a multiple of the ATR below or above their entry point to account for volatility.
  • Position Sizing: By assessing volatility through the ATR, traders can adjust their position sizes accordingly to manage risk effectively.
  • Trailing Stops: The ATR can be used to create dynamic trailing stops that adapt to market conditions.

strategy("[Pineify - Best Pine Script Generator] ATR Trailing Stop", overlay=true)

// User Inputs
atrLength = input.int(14, title="ATR Length")
atrMultiplier = input.float(1.0, title="ATR Multiplier")
barLookback = input.int(10, title="Bar Lookback")

// Calculate ATR
atrValue = ta.atr(atrLength)

// Determine Stop Loss Levels
longStop = low - atrValue * atrMultiplier
shortStop = high + atrValue * atrMultiplier

// Entry Conditions

    strategy.entry("Long", strategy.long)

if (ta.crossunder(close, ta.sma(close, 14)))
    strategy.entry("Short", strategy.short)

// Exit Conditions with Trailing Stops
strategy.exit("Long Exit", "Long", stop=longStop)
strategy.exit("Short Exit", "Short", stop=shortStop)

In this example:

  • We calculate both long and short stop loss levels based on the current price and the ATR.
  • The script enters long or short positions based on moving average crossovers and exits based on the calculated trailing stops.

Conclusion​

The Average True Range is an essential tool for traders looking to gauge market volatility and manage risk effectively. By utilizing Pine Script to implement the ATR in your trading strategies, you can enhance your decision-making process and potentially improve your trading outcomes.
