hello everyone please can someone help me with stock price prediction. That is I wrote this code and from the I vector , I want a code that will remove indexes from the I vector more than 60 seconds. Thanks

1 view (last 30 days)
LSE_matrix =log(nstock_val); %log of the data
I=1:(size(LSE_matrix,1)-1); % selecting the indices of all prices but the last time when stock was opened
dLSE_col1 = LSE_matrix(I+1,1) - LSE_matrix(I,1);% log difference

You can adapt this to your needs
A = readtable('LSE1.csv')
t = datetime(A{:,1},'inputformat','dd.MM.yyyy HH:mm:ss.SSS')
data = A{:,2:end};
id = [false;diff(t)>seconds(60)];
data(id,:) = [];
t(id) = [];
If the period between t(n) and t(n+1) is longer than 60s, then the data recorded at t(n+1) is deleted.
