To compute the Average True Range (ATR) in 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 |
public class ATRCalculator { public static double calculateATR(double[] high, double[] low, double[] close, int period) { double[] ATR = new double[close.length]; ATR[0] = high[0] - low[0]; for (int i = 1; i < close.length; i++) { double tr1 = high[i] - low[i]; double tr2 = Math.abs(high[i] - close[i - 1]); double tr3 = Math.abs(low[i] - close[i - 1]); double trueRange = Math.max(tr1, Math.max(tr2, tr3)); ATR[i] = ((ATR[i - 1] * (period - 1)) + trueRange) / period; } return ATR[close.length - 1]; } public static void main(String[] args) { double[] high = {10, 12, 15, 13, 18}; double[] low = {5, 7, 10, 8, 12}; double[] close = {8, 9, 12, 11, 16}; int period = 4; double atr = calculateATR(high, low, close, period); System.out.println("Average True Range (ATR): " + atr); } } |

In the `calculateATR`

method, we calculate the True Range for each data point using the formula:

```
1
``` |
TR = max(high - low, |high - previous close|, |low - previous close|) |

We then calculate the ATR based on the True Range values and the given period.

The `main`

method demonstrates how to use the `calculateATR`

method with sample data. You can replace the sample data with your own high, low, close values and adjust the period as needed.
