Filling missing dates

Hi.

I have the following scripts and I am showing the results in images.

When I execute this:

;
  WITH  base
          AS ( SELECT   FECHAVALORBANCO ,
                        SUM(MovDebitoCOP) - SUM(MovCreditoCOP) AS saldofinal ,
                        SUM(MovDebitoCOP) sum_MovDebitoCOP ,
                        SUM(MovCreditoCOP) AS sum_MovCreditoCOP
               FROM     DetalleLibroBancos
                        INNER JOIN OperacionesBancarias ON DetalleLibroBancos.IdOpBancaria = OperacionesBancarias.IDOPBANCARIA
               GROUP BY FECHAVALORBANCO
             ),
        new
          AS ( SELECT   a.FECHAVALORBANCO ,
                        ISNULL(b.saldofinal, 0.00) start ,
                        ISNULL(a.saldofinal, 0.00) final ,
                        ISNULL(a.sum_MovDebitoCOP, 0.00) sum_MovDebitoCOP ,
                        ISNULL(a.sum_MovCreditoCOP, 0.00) sum_MovCreditoCOP
               FROM     base a
                        LEFT OUTER JOIN base b ON a.FECHAVALORBANCO = b.FECHAVALORBANCO+ 1
             )
    INSERT  INTO dbo.SaldoDiarioLibroBancos
            ( Fecha ,
              SaldoInicialDia ,
              SaldoFinalDia
	        )
            SELECT  FECHAVALORBANCO ,
                    start Saldoinicialdia ,
                    start + sum_MovDebitoCOP - sum_MovCreditoCOP saldofinaldia
            FROM    new
            ORDER BY 1

I get this table

The table that I need is this table:

When movdebitocop is not null it sums if movcreditocop is not null it substract.

Saldoinicialdia is the value of saldofinaldia of the previous day and saldofinaldia is saldoinicialdia of the current day sum or substract depending of the movements of the current day.

For example for 2013-01-02 saldoinicialdia is 9 because saldofinaldia of the previous day is 9. Saldofinaldia for 2013-01-05 is 0 because there were two movcreditocop  movements in 2013-01-05  -8-1=-9         then 9-9=0

I don't know how to fill the missing dates.

How can I do to get the required table?

Thanks.
