Hey guys,
I used the following code for this problem, hope it helps someone:

Private Sub Worksheet_Calculate()
Static oldValue
If Range("MyNamedRange") <> oldValue Then
CodeHere
oldValue = Range("MyNamedRange").Value
End If
End Sub

Hello, Cenk,
The macro name is the macro code you have inserted into the Excel file, and you just need to change the Macro1 in the above code to your own.
For example, i insert a code here, and the macro name is: ColorCompanyDuplicates

Sub ColorCompanyDuplicates()
'Updateby Extendoffice 20160704
Dim xRg As Range
Dim xTxt As String
Dim xCell As Range
Dim xChar As String
Dim xCellPre As Range
Dim xCIndex As Long
Dim xCol As Collection
Dim I As Long
On Error Resume Next
If ActiveWindow.RangeSelection.Count > 1 Then
xTxt = ActiveWindow.RangeSelection.AddressLocal
Else
xTxt = ActiveSheet.UsedRange.AddressLocal
End If
Set xRg = Application.InputBox("please select the data range:", "Kutools for Excel", xTxt, , , , , 8)
If xRg Is Nothing Then Exit Sub
xCIndex = 2
Set xCol = New Collection
For Each xCell In xRg
On Error Resume Next
xCol.Add xCell, xCell.Text
If Err.Number = 457 Then
xCIndex = xCIndex + 1
Set xCellPre = xCol(xCell.Text)
If xCellPre.Interior.ColorIndex = xlNone Then xCellPre.Interior.ColorIndex = xCIndex
xCell.Interior.ColorIndex = xCellPre.Interior.ColorIndex
ElseIf Err.Number = 9 Then
MsgBox "Too many duplicate companies!", vbCritical, "Kutools for Excel"
Exit Sub
End If
On Error GoTo 0
Next
End Sub
