To compute Average True Range (ATR) using Java, you can use the following code snippet:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 |
public class ATRCalculator { public double calculateATR(double[] highs, double[] lows, double[] closes, int period) { double[] trueRanges = new double[highs.length]; // Calculate True Range for each period for (int i = 1; i < highs.length; i++) { double trueRange = Math.max(highs[i] - lows[i], Math.max(Math.abs(highs[i] - closes[i - 1]), Math.abs(lows[i] - closes[i - 1]))); trueRanges[i] = trueRange; } // Calculate Average True Range using Exponential Moving Average (EMA) double atr = 0; double multiplier = 2.0 / (period + 1); for (int i = 0; i < period; i++) { atr += trueRanges[i]; } atr /= period; for (int i = period; i < highs.length; i++) { atr = ((trueRanges[i] - atr) * multiplier) + atr; } return atr; } public static void main(String[] args) { double[] highs = {10, 12, 14, 15, 16}; double[] lows = {8, 10, 12, 13, 14}; double[] closes = {9, 11, 13, 14, 15}; ATRCalculator atrCalculator = new ATRCalculator(); double atr = atrCalculator.calculateATR(highs, lows, closes, 3); System.out.println("Average True Range (ATR): " + atr); } } |

In this code snippet, the `calculateATR`

method takes as input arrays of highs, lows, and closing prices, as well as the period for which the ATR is calculated. It then calculates the True Range for each period and uses Exponential Moving Average (EMA) to compute the Average True Range (ATR). The `main`

method demonstrates how to use this method with sample data.
