How to download stock data from matlab?

To download stock data from MATLAB, you can use the built-in function yahoo. Here's a step-by-step guide:

1. Open MATLAB and create a new script by clicking on "New Script" in the "Home" tab.
2. In the script, define the ticker symbol of the stock you want to download data for, the start and end date of the data, and the frequency of the data points. For example:

1
2
3
4

ticker = 'AAPL';  % Ticker symbol of Apple stock
startDate = '01-Jan-2020';
endDate = '31-Dec-2020';
frequency = 'daily';

1. Use the yahoo function to download the stock data. The function will return a table with the downloaded data. Assign the output to a variable, such as data. For example:

1

data = yahoo(ticker, startDate, endDate, frequency);

1. You can now access and analyze the downloaded data. For example, you can plot the closing prices over time:

1
2
3
4

plot(data.Date, data.Close);
xlabel('Date');
ylabel('Closing Price');
title('Stock Data');

1. Save the script and click the "Run" button in the editor toolbar to execute the code.

This approach uses the Yahoo Finance API, which may have limitations or require authentication. Alternatively, you can use other APIs or data sources available in MATLAB, such as Alpha Vantage, Quandl, or Bloomberg.
