Creating a mesure that operates two lines of the same columm

[Gabrielpibx]

I have a columm with the agragation of all consumation called "leitura" and i need to creat a mesure that calculates the consumation per day. Can i create this mesure using only this columm and the columm of date in the same table? The operation will be something like, the latest date minus the previous day and i need to calculate it for all period of time in the table. The table im referring is below

   

So far im using this code: 

CD =

CALCULATE (

    VAR LEITURADODIA = LASTDATE('Hidrômetros'[Inserção])

    VAR LEITURADODIAANTERIOR = PREVIOUSDAY(LASTDATE('Hidrômetros'[Inserção]))

    RETURN

     IF([DATEDIFF]=0,"",

     SUMX('Hidrômetros',CALCULATE([VALORLEITURA],'Hidrômetros'[Inserção]=LEITURADODIA)- CALCULATE([VALORLEITURA],'Hidrômetros'[Inserção]=LEITURADODIAANTERIOR))),

     'Hidrômetros'[Apelido]="Macromedidor"

)

But i only got the result for the two last days in the table.
