To calculate Chaikin Money Flow (CMF) using Java, you can follow these steps:
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 CMFCalculator { public static double calculateCMF(double[] closePrices, double[] highPrices, double[] lowPrices, int[] volumes, int period) { double[] moneyFlowVolume = new double[closePrices.length]; double[] moneyFlowMultiplier = new double[closePrices.length]; double sumMFV = 0; double sumVolume = 0; for (int i = 0; i < closePrices.length; i++) { moneyFlowVolume[i] = ((closePrices[i] - lowPrices[i]) - (highPrices[i] - closePrices[i])) / (highPrices[i] - lowPrices[i]) * volumes[i]; moneyFlowMultiplier[i] = moneyFlowVolume[i] * ((double)volumes[i]); if (i >= period) { sumMFV -= moneyFlowMultiplier[i - period]; sumVolume -= volumes[i - period]; } sumMFV += moneyFlowMultiplier[i]; sumVolume += volumes[i]; double cmf = sumMFV / sumVolume; return cmf; } } } |

public class Main { public static void main(String[] args) { double[] closePrices = {100, 105, 110, 115, 120}; double[] highPrices = {105, 110, 115, 120, 125}; double[] lowPrices = {95, 100, 105, 110, 115}; int[] volumes = {100000, 110000, 120000, 130000, 140000}; int period = 5; double cmf = CMFCalculator.calculateCMF(closePrices, highPrices, lowPrices, volumes, period); System.out.println("Chaikin Money Flow (CMF): " + cmf); } } |

The implementation provided to calculate the Chaikin Money Flow (CMF) using Java has some issues. Here's the corrected version of the given code:
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 40 41 42 |
public class CMFCalculator { public static double calculateCMF(double[] closePrices, double[] highPrices, double[] lowPrices, int[] volumes, int period) { double[] moneyFlowVolume = new double[closePrices.length]; double[] moneyFlowMultiplier = new double[closePrices.length]; double sumMFV = 0; double sumVolume = 0; for (int i = 0; i < closePrices.length; i++) { moneyFlowVolume[i] = ((closePrices[i] - lowPrices[i]) - (highPrices[i] - closePrices[i])) / (highPrices[i] - lowPrices[i]) * volumes[i]; moneyFlowMultiplier[i] = moneyFlowVolume[i] * volumes[i]; if (i >= period) { sumMFV -= moneyFlowMultiplier[i - period]; sumVolume -= volumes[i - period]; } sumMFV += moneyFlowMultiplier[i]; sumVolume += volumes[i]; } double cmf = sumMFV / sumVolume; return cmf; } } public class Main { public static void main(String[] args) { double[] closePrices = {100, 105, 110, 115, 120}; double[] highPrices = {105, 110, 115, 120, 125}; double[] lowPrices = {95, 100, 105, 110, 115}; int[] volumes = {100000, 110000, 120000, 130000, 140000}; int period = 5; double cmf = CMFCalculator.calculateCMF(closePrices, highPrices, lowPrices, volumes, period); System.out.println("Chaikin Money Flow (CMF): " + cmf); } } |
This corrected version of the code includes fixing the calculation of moneyFlowMultiplier
and moving the return statement outside the loop to calculate the CMF correctly. You can run this updated code to get the correct Chaikin Money Flow (CMF) value.
