DAX Command for getting Avg (%) of the previous 2 weeks

[luvnet18]

Want to show a single column of (B) Implied Closing Rate by weekly trend when it's latest 2 weeks (WkFlag=0 and -1) then show (B) Implied Close Rate, otherwise show (A) Closing Rate

(A) Closing Rate = Booked/Quoted
(B) Implied Closing Rate = Only happen on last 2 Weeks.   Calculation = Closing Rate Average of the Previous 2 Weeks

Sample Implied Calculation :-

Wk5 (WkFlag -1) =AVERAGE(18.52%,19.39%)=18.96%
Wk6 (WkFlag 0) =AVERAGE(19.39%,18.96%)=19.17%

@luvnet18 , In your date or week table can you create a rank column

Week Rank = RANKX(all('Date'),'Date'[Week Start date],,ASC,Dense)
OR
Week Rank = RANKX(all('Date'),'Date'[Year Week],,ASC,Dense) //YYYYWW format

Then you can deal with a week like

This Week = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])))
Last Week = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])-1))
Last year Week= CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=(max('Date'[Week Rank]) -52)))
Last 2 weeks = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]>=max('Date'[Week Rank])-2 && 'Date'[Week Rank]<=max('Date'[Week Rank])))

I already have a field WkFlag=0 Last Week and WkFlag=-1 as the 2nd last week.

However, I need a formula to Calculate Implied Closing Rate for WkFlag=0 and WkFlag=-1 using Average Closing Rate of the previous 2 weeks
