question:::::

Go to finance.yahoo.com. Download data for a stock of your choice.

Data download: type in the stock symbol, then go to historical data, select starting date and end date (01/01/2006 to 12/31/2016).

save ot as a csv file (comma separated values)

Use Adjusted close for all computations

Q1: Compute the 20 days moving average: avg(n) = avg(n-1)*factor + close of today*(1-factor)

Q2: Compute the standard deviation at each day.

My answer code is>>>>>>>>>>>>>>>>>>>>.

import java.io.BufferedReader; import java.io.FileReader; import java.io.IOException; public class Stocks { static double values[] = new double[1000]; static double averages[] = new double[1000]; static int no_of_values = 0; public static void main(String[] args) throws NumberFormatException, IOException { BufferedReader reader = new BufferedReader(new FileReader("stock_data.csv")); String line; reader.readLine(); // to ignore first line of comments; double factor= 0.5;

// red data.. and store in values array while ((line = reader.readLine()) != null) { String tokens[] = line.split(","); values[no_of_values++] = Double.parseDouble(tokens[4]); } if (no_of_values > 0) { averages[0] = values[0]; // considering a factor of 0.5 in moving average //Compute the 20 days moving average: avg(n) = avg(n-1)*factor + close of today*(1-factor) for (int i = 1; i

} } reader.close(); } }

Note: an you please compute it by

EMA

SMA

STD

Once file have to read it and write and compute data in the file.

can you please use those system...

can you please send me a new copyable code, thank you so much?
