Good Morning,

I have the following statement that check 3 data sets to combine an answer (1,0,-1) but i am not able to get it to work. I am new in MATLAB and i am able to get an excel statement that works (attached in file).

sOpen = zeros(size(sOpen));
sClose = zeros(size(sOpen));
sCombined = zeros(size(sOpen));
for k = 2:numel(sOpen)
    kk = sOpen(k)~=0 && sClose(k)~=0;            % To check if there is a value -1 or 1 in sOpen and sClose
    if all(kk)                                   
    kkk = sCombined(k-1)==-1 & sClose(k) ==1;    % If prior combined result equals -1 and current CLOSE = 1 then result = 1
    sCombined(k) = 1;
    elseif all(~kkk)
    kkkk = sCombined(k-1)==0 & sOpen(k) ==-1;    % If prior combined result equals 0 and current OPEN = -1 then result = -1
    sCombined(k) = -1;
    elseif all(~kkk)
    kkkkk = sCombined(k-1)==-1 & sClose(k) ==0;  % If prior combined result equals -1 and current CLOSE = 0 then result = -1
    sCombined(k) = -1;
    else
    sCombined(k) = 0;                             %Anything else should be 0
    end
end

Data.xlsx

Here is a direct translation of your Excel formula:

T = readtable('Data.xlsx') % import your data
Warning: Column headers from the file were modified to make them valid MATLAB identifiers before creating variable names for the table. The original column headers are saved in the VariableDescriptions property.
Set 'VariableNamingRule' to 'preserve' to use the original column headers as table variable names.
T = 4252×5 table
