Hi everyone,

I would like to use the MACD index and state the following if expressions in one loop, ie for every time t. First, I get the MAC index as follows

[macdvec, nineperma] = macd(y);
 1) if macdev(t)>nineperma(t) then MACD(t)=1
 2) if macdev(t)<nineperma(t) then MACD(t)=0
 3) if macdev(t-1)<nineperma(t-1) and macdev(t)=nineperma(t) then MACD(t)=1  
 4) if macdev(t-1)>nineperma(t-1) and macdev(t)=nineperma(t) then MACD(t)=0

How can I state several if statements into a single loop?

Thanks a lot in advance

gsourop - couldn't you do something like

 [macdvec, nineperma] = macd(y);
 myMacData = zeros(length(macdvec),1);
 for t=1:length(macdvec)
     if macdev(t)>nineperma(t)
         myMacData(t)=1;
     elseif macdev(t)<nineperma(t)
         % etc.
     elseif
         % etc.
     elseif
         % etc.
     endif
 end
