Hi, I am not sure I fully understand what you mean by the 'last first highest', but based on the picture it looks like you are looking for the most recent Peak? With the Peak function you must specify a minimum percent change to what constitutes a peak. For example: Peak(1,H,3)

Here are a couple of options that identify peak values without requiring a specific percentage. The 3 bar peak value is not available until 1 bar after the apex, and the 5 bar peak value is not available until 2 bars after the apex.

{3 Peak Bar}
Pk1:=Ref(H,-1)>Ref(H,-2) AND Ref(H,-1)>H;
ValueWhen(1,Pk1,Ref(H,-1));

{5 Peak Bar}
Pk2:=Ref(H,-2)>H AND Ref(H,-2)>Ref(H,-1) AND
Ref(H,-2)>Ref(H,-3) AND Ref(H,-2)>Ref(H,-4);
ValueWhen(1,Pk2,Ref(H,-2));

These alternatives to the Peak() function should not be considered as either better or worse but might well be more appropriate in some situations.
