Question
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 MATLABExplanation / Answer
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
