Hi,
I'm trying to program the "TD-setup squence of the TD-Sequential DeMark indicator.

parameters are as follows:
we need to see a "Bearish flip", defined as follows:
closing price has to be lower then closing price 4 bars ago And;
Yesterdays closing price has to be higher then closing bar 4 bars ago (relative to yesterdays bar).

if this holds true we can start the TD- buy setup. defined as follows.
note : the bar that passed the bearish flip willbe the first bar of the TD-buy setup.
there must be 9 consecutive closes, each one less then the corresponding close 4 bars earlier.

I have created some real-code, using the CASE statement :

Static DayCount As Integer
Static TDcount As Integer

' first check if we start at the 5th bar

If isFirstBar Then
 plot = Single.NaN
 DayCount = 0
 TDcount = 0
Else
 DayCount += 1
 
End If

' we're on the 5th bar, or higher

If daycount >= 5 Then
 
 Select Case tdcount
  'this is the Bearish TD price flip, which if true, puts us on the first bar of the TD-Buy setup
 Case 0
  If Price.Close < price.Close(4) AndAlso _
   Price.Close(1) > price.Close(5) Then
   TDcount += 1
   label = tdcount
   plot = tdcount
  End If
 Case 1
  If Price.Close < price.Close(4) Then
   TDcount += 1
   label = tdcount
   plot = tdcount
  Else
   tdcount = 0
  End If
 Case 2
  If Price.Close < price.Close(4) Then
   TDcount += 1
   label = tdcount
   plot = tdcount
  Else
   tdcount = 0
  End If
 Case 3
  If Price.Close < price.Close(4) Then
   TDcount += 1
   label = tdcount
   plot = tdcount
  Else
   tdcount = 0
  End If
 Case 4
  If Price.Close < price.Close(4) Then
   TDcount += 1
   label = tdcount
   plot = tdcount
  Else
   tdcount = 0
  End If
 Case 5
  If Price.Close < price.Close(4) Then
   TDcount += 1
   label = tdcount
   plot = tdcount
  Else
   tdcount = 0
  End If
 Case 6
  If Price.Close < price.Close(4) Then
   TDcount += 1
   label = tdcount
   plot = tdcount
  Else
   tdcount = 0
  End If
 Case 7
  If Price.Close < price.Close(4) Then
   TDcount += 1
   label = tdcount
   plot = tdcount
  Else
   tdcount = 0
  End If
 Case 8
  If Price.Close < price.Close(4) Then
   TDcount += 1
   label = tdcount
   plot = tdcount
   tdcount = 0
  End If
 
End Select

Else
 setindexinvalid
End If

It seems to work ok, but I have some cases were it skips a few bars between the 8'th and 9th count. see pic.
I don't understand why.

Static TDcount As Integer

' first check if we start at the 5th bar

If isFirstBar Then
 plot = Single.NaN
 TDcount = 0
End If

' we're on the 5th bar, or higher

If currentIndex >= 5 Then
 
 Select Case tdcount
  'this is the Bearish TD price flip, which if true, puts us on the first bar of the TD-Buy setup
  Case 0
   If Price.Close < price.Close(4) AndAlso _
    Price.Close(1) > price.Close(5) Then
    TDcount += 1
    label = tdcount
    plot = tdcount
   End If
  Case Else
   If Price.Close < price.Close(4) Then
    TDcount += 1
    label = tdcount
    plot = tdcount
   Else
    tdcount = 0
   End If
 End Select
Else
 setindexinvalid
End If
If tdCount = 9 Then
 tdCount = 0
End If

"Case Else"   !!!  didn't know that one.  cool!.
