To calculate Chaikin Money Flow (CMF) using MATLAB, you can follow these steps:

  1. Load the necessary data into MATLAB. This can be stock price data or any other financial data that you want to analyze.
  2. Calculate the Money Flow Multiplier (MFM) for each period. MFM is calculated as follows: Money Flow Multiplier = ((Close - Low) - (High - Close)) / (High - Low) Where: Close is the closing price for the period Low is the lowest price for the period High is the highest price for the period
  3. Calculate the Money Flow Volume (MFV) for each period. MFV is calculated as follows: Money Flow Volume = Money Flow Multiplier * Volume
  4. Calculate the 21-period CMF. This can be done by summing the MFV for the last 21 periods and dividing it by the sum of the Volume for the last 21 periods. This will give you the 21-period CMF.
  5. Plot the CMF values on a chart to visualize the trend.


Here is a sample code snippet to calculate CMF in MATLAB:

% Load the data
data = readtable('stock_data.csv');

% Calculate Money Flow Multiplier
MFM = ((data.Close - data.Low) - (data.High - data.Close)) ./ (data.High - data.Low);

% Calculate Money Flow Volume
MFV = MFM .* data.Volume;

% Calculate 21-period CMF
CMF = sum(MFV(end-20:end)) / sum(data.Volume(end-20:end));

% Plot the CMF values
plot(data.Date, CMF);
xlabel('Date');
ylabel('Chaikin Money Flow (CMF)');
title('Chaikin Money Flow (CMF) Chart');


Make sure to replace 'stock_data.csv' with the actual file containing your data. This code snippet will calculate and plot the 21-period CMF values for the given data. Feel free to customize the code based on your specific requirements.
