and , next code , maybe cover really all your needs :

Sub GIVEATRYFORSTEPTWO()

Dim FromWbook As Worksheet
Dim myCell As Range
Dim myRng1 As Range

Set FromWbook = Workbooks("YYYYY.xls").Worksheets("YYYYY")

With FromWbook
Set myRng1 = .Range("G11:G71")
End With

For Each myCell In myRng1.Cells
If myCell.Value < 0 Then
myCell.Font.ColorIndex = 4
ElseIf myCell.Value 0 Then
myCell.Font.ColorIndex = 3
Else
End If
If myCell.Value = 9 Then
myCell.Select
Selection.Font.Bold = True
Selection.Font.ColorIndex = 1
With Selection.Interior
.ColorIndex = 3
.Pattern = xlSolid
End With
ElseIf myCell.Value = -9 Then
myCell.Select
Selection.Font.Bold = True
Selection.Font.ColorIndex = 1
With Selection.Interior
.ColorIndex = 4
.Pattern = xlSolid
End With
Else
End If
Next myCell

End Sub
