The information is shown below for the 20 daysto make the Simple Moving Average Filters. Use the first 5 days for the short-term filter and all the days for the long-term filter. Be careful not to make any careless mistakes as it is very easy to go wrong in taking down the values.

In MATLAB create a short-term SMA filter (-5 days) and a longer-term SMA filter 20 days) and apply these to the closing prices of your stocks (use MATLAB filter function to do this). Plot the outputs in MATLAB

Solution

MATLAB code is

function [P] = filter123(A)
[x]=textread(\'filterdata.txt\',\'%s\');
j=1;
k=1;
for i=1:A
    p(j)=x(k,1);
    q(j)=x(k+2,1);
    k=k+3;
    j=j+1;
end
plot(p,q)
end
