Calculate Stock certain month

[feralvarez994]

Hi everyone, i have a table with cars code, buy date and sell date, seller, buyer and city, also a calendar table. The calendar table and the car table are linked by buy date

I have two filters in the page (year and month filter separately)

I want to calculate the stock by the month and year selected, by counting the cars that have been bought before the first day of the month/year selected and hasnt been sold OR had been sold after the same starting day of the month. Also i want to display this by seller and by city in a table to calculate the stock rotation.

How can a i calculate this ? Im using this measure but its not working

Stock autos = CALCULATE(

             COUNTROWS(AUTOS),

             FILTER(

                 'AUTOS',

                 'AUTOS'[FECHA COMPRA] <= FIRSTDATE(Calendario[Fecha])

                 && (AUTOS[Fecha Reserva] >= STARTOFMONTH(Calendario[Fecha])

                     || ISBLANK(AUTOS[Fecha Reserva]))

                 && YEAR(AUTOS[FECHA COMPRA]) = YEAR(SELECTEDVALUE(Calendario[Fecha])

                 && MONTH(AUTOS[FECHA COMPRA]) = MONTH(SELECTEDVALUE(Calendario[Fecha]))

             )

         ))

Filters in the page (year selected and month selected)

Try

Stock autos =
VAR MinDate =
    MIN ( 'Calendar'[Date] )
VAR Result =
    CALCULATE (
        COUNTROWS ( Autos ),
        'Calendar'[Date] <= MinDate,
        Autos[Sell date] > MinDate
            || ISBLANK ( Autos[Sell date] )
    )
RETURN
    Result

You don't need to explicitly specify a filter for the buy date, the relationship with the calendar table will do that, and by specifying a filter on the date column of the calendar table that will automatically remove any filters on the calendar table from your slicers, as long as it is marked as a date table.
