## Find the last day value;

I intend to calculete the day by day price variation between the values of public traded stocks using DAX.After hour of reserch, I constructed the following expression, that gave me the current and the last price:

```SUMMARIZE (
Inf_diario,
"PREVIOUS VL",
VAR previousDate =
MAXX (
FILTER (
Inf_diario,
Inf_diario[CNPJ_FUNDO] = EARLIER ( Inf_diario[CNPJ_FUNDO] )
&& Inf_diario[DT_COMPTC] < EARLIER ( Inf_diario[DT_COMPTC] )
),
Inf_diario[DT_COMPTC]
)
RETURN
MAXX (
FILTER (
Inf_diario,
Inf_diario[CNPJ_FUNDO] = EARLIER ( Inf_diario[CNPJ_FUNDO] )
&& Inf_diario[DT_COMPTC] = previousDate
),
Inf_diario[VL_QUOTA]
)
),
Inf_diario[ID],
Inf_diario[DT_COMPTC],
Inf_diario[VL_QUOTA],
[PREVIOUS VL]
)```

The results:

Now, I need to find the diference between the PREVIOUS VL and VL QUOTA (current value), to finally calculate Standard deviation, %change etc.

It seems you are modeling off a single table and created a second calculated table. If so, i would do things a bit differently.  I would use measures instead.   First, put 'id' and 'DT_COMPTC' on rows of Matrix, then add the following measures:

`VL_Quota measure = SUM (Inf_diario[VL_Quota] )`

then:

```Previous VL Measure =
VAR _dates =
FILTER (
ALL ( Inf_diario[DT_COMPTC] ),
Inf_diario[DT_COMPTC] < MAX ( Inf_diario[DT_COMPTC] )
)
VAR _previousDate =
LASTNONBLANK ( _dates, [VL_Quota measure] )
RETURN
CALCULATE ( [VL_Quota measure], Inf_diario[DT_CoMPTC] = _previousDate )```

then your % change is easy:

```% Change =
DIVIDE ( [Previous DL Measure] - [VL_Quota measure], [VL_Quota measure] )```

and so on.

But if you want to continue to use your calculated table, you'll need to add more values via the ADDCOLUMNS you have.

```% Change =
DIVIDE ( [Previous DL Measure] - [VL_Quota measure], [VL_Quota measure] )```

and so on.
