Of course you can also add logic to recalculate the sheet automatically at regular intervals. One way to do this could be to add a new module with, for example, the following code:

Private Running As Boolean

Public Sub StartTimer()
    Running = True
    Call TimerEvent
End Sub

Public Sub StopTimer()
    Running = False
End Sub

Public Sub TimerEvent()
    Workbooks("Book1").Worksheets(1).Calculate
    If Running Then
        Application.OnTime Now + TimeValue("00:00:10"), "TimerEvent"
    End If
End Sub

(Note that you'd need to replace "Book1" with the appropriate name, or simply use ActiveWorkbook in place of Workbooks("Book1"), although then the timer will be recalculating whatever workbook you have open at the moment).

You can start the timer by running the StartTimer macro (using the "Run" button) and stop it using StopTimer.

It might make sense to also add something like this to the code of ThisWorkbook module, so that the timer will start and stop automatically:

Private Sub Workbook_Open()
    Call StartTimer
End Sub

Private Sub Workbook_BeforeClose(Cancel As Boolean)
    Call StopTimer
End Sub
