Hi,

I need some help to get Excel to extract all the smallest numbers [RED] in a repeating data sequence that goes from maximum to mininum and back to maximum...

What does "
sequence that goes from maximum to mininum and back to maximum" mean? Would you do the explanation with respect to 1.31 and 5.15?​

... which you could use as a CF formula.

Hi,

The data is actually in degrees of rotation (360). It goes from 360 to 0 to 360 to 0 to 360.... (max to min to max to min...)
I just want to capture all the minimum angles before it goes back up again in long sequence of data.

If you put =AND((SIGN((B1-B2)*(B2-B3))<0),(B2 < B1)) in B2 and drag down, it will return TRUE when B2 is a minimum relative to B1 and B3.

It is not clear what exactly you are looking for for a solution... here is a macro that will do what I think you want.
Code: 
[table="width: 500"]
[tr]
	[td]Sub HighlightMinimumValues()
  Dim R As Long, Data As Variant
  Data = Range("B1", Cells(Rows.Count, "B").End(xlUp))
  Columns("B").Cells.Font.ColorIndex = vbBlack
  For R = 2 To UBound(Data) - 1
    If Data(R, 1) < Data(R - 1, 1) And Data(R, 1) < Data(R + 1, 1) Then
    Cells(R, "B").Font.Color = vbRed
    End If
  Next
End Sub[/td]

I got it. Formula should be in C2 instead of C1.

You should have said you were looking for a formula solution in your original message. Here is another formula you can consider (place it in cell C2 and copy down)...

=AND(B3<=B2,B3<=B4)

Note: If you decide to stay with Mike's formula, you might want to change both of his "less than" signs to "less than or equal" signs so that it will mark multiple adjacent exact minimum values as TRUE instead of FALSE. My formula above already handles this situation.
