Hi,
I have 2 tables: factPosition and dimDate. What I'm trying to do is calculate the Average for the closing price, for the last 5 days for each symbol:
TestSymbolAverage5Day:=
AVERAGEX (
SUMMARIZE (
DatesInPeriod( V_dimDate[DateValue],LastDate(V_dimDate[DateValue]),-5,DAY),
V_dimDate[DateValue]
),
CALCULATE ( [Sum of ClosePosition] )
)
The above works when I have 5 consecutive days however the weekend dates are not populated so the average is incorrect:
How do I change my formular so it only works on the days where I have a "SUM of ClosePrice" populated?
Thanks
Bob
Solved! Go to Solution.
Make these two changes to your code:
TestAverage5days := AVERAGEX ( TOPN ( 5, CALCULATETABLE ( SUMMARIZE ( factEODPosition, dimDate[DateValue] ), DATESBETWEEN ( dimDate[DateValue], BLANK (), MAX ( dimDate[DateValue] ) ) ), dimDate[DateValue] ), CALCULATE ( SUM ( [ClosePosition] ) ) )
Hi @BeginnerBob
I am assuming that factPosition only contains rows with populated ClosePosition values, so that the dates existing in factPosition are populated dates.
If so, then try a measure like this:
Average Sum of ClosePosition for last 5 populated dates = AVERAGEX ( TOPN ( 5, CALCULATETABLE ( SUMMARIZE ( factPosition, dimDate[Date] ), DATESBETWEEN ( dimDate[Date], BLANK (), MAX ( dimDate[Date] ) ) ), dimDate[Date] ), [Sum of ClosePosition] )
The code in green returns a table of dates which exist in factPosition up to the max date in the filter context. Then TOPN grabs the top (i.e. latest) 5 of these.
In order to suppress this measure when you have gone past the last date in factPosition, you could add a check to the measure:
Average Sum of ClosePosition for last 5 populated dates = IF ( MIN ( dimDate[Date] ) <= CALCULATE ( MAX ( factPosition[Date] ), ALL ( factPosition ) ), AVERAGEX ( TOPN ( 5, CALCULATETABLE ( SUMMARIZE ( factPosition, dimDate[Date] ), DATESBETWEEN ( dimDate[Date], BLANK (), MAX ( dimDate[Date] ) ) ), dimDate[Date] ), [Sum of ClosePosition] ) )

HI,
Thanks for you response. This doesn't seem to work the values which are returned are the close position:
TestAverage5days:=AVERAGEX ( TOPN ( 5, CALCULATETABLE ( SUMMARIZE ( factEODPosition, dimDate[DateValue]), DATESBETWEEN ( dimDate[DateValue], MIN ( dimDate[DateValue]) , MAX (dimDate[DateValue]) ) ), dimDate[DateValue] ), SUM( [ClosePosition]) )
My dimDate[DateValue] is highlighted red, which is a little strange. My code compliles but an average isn't returned, just the SUM[ClosePosition].
Any ideas?
Thanks
