Average total calculated by weekly date

Hi, KatBous 

You can try the following methods.
Measure:

Count open =
VAR _N1 =
    CALCULATE (
        COUNT ( 'Table'[Position Title] ),
        FILTER (
            ALL ( 'Table' ),
            [Date position opened] <= SELECTEDVALUE ( 'Report date'[Date] )
                && [Date position closed] >= SELECTEDVALUE ( 'Report date'[Date] )
                && [Date position closed] <> BLANK ()
        )
    )
VAR _N2 =
    CALCULATE (
        COUNT ( 'Table'[Position Title] ),
        FILTER (
            ALL ( 'Table' ),
            [Date position closed] = BLANK ()
                && [Date position opened] <= SELECTEDVALUE ( 'Report date'[Date] )
        )
    )
RETURN
    _N1 + _N2

Count closed = 
CALCULATE (
    COUNT ( 'Table'[Position Title] ),
    FILTER (
        ALL ( 'Table' ),
        [Date position closed] <= SELECTEDVALUE ( 'Report date'[Date] )
            && [Date position closed] <> BLANK ()
    )
)

Is this the result you expect?
