Moving Average on 2 Measures

[DataSundowner]

Hello everyone. I have a question on DAX to calculate moving average. Can I do moving average on 2 measures: 1 measure is sum of historical data calculation, the other measure is sum of forecast calculation? I know how to do moving average on them individually, but I'd like to combine them and do the moving average on both historical and forecast together.

Say I have some sales data and 2 measures such as below. The yellow highlighted, 3 Days MA Combined is the result I'm looking for. Any hint or advice is appreciated.

Hi,

I tried to create a sample pbix file like below.

Please check the below picture and the attached pbix file.

I hope this can provide some ideas on how to create a solution for your data model.

Moving avg 3days: = 
VAR _currentdate =
    MAX ( 'Calendar'[Date] )
VAR _threedaysbefore = _currentdate - 2
VAR _condition =
    CALCULATE ( [Sales combine measure:], 'Calendar'[Date] = _threedaysbefore )
        <> BLANK ()
        && [Sales combine measure:] <> BLANK ()
RETURN
    AVERAGEX (
        DATESINPERIOD ( 'Calendar'[Date], LASTDATE ( 'Calendar'[Date] ), -3, DAY ),
        [Sales combine measure:]
    )
        * DIVIDE ( _condition, _condition )

Thank you @Jihwan_Kim. The dax didn't work in my model, but your idea of adding up historical and forecast to combine them helped me a lot and and I figured out the rest.
