Increase, decrease Icon week on week

[Kpiuser]

Hi guys - I have a Matrux table below Date in column field that is counting all the number of clients by status over the weekly periods.
I would like to  add an Arrow Green and Red icons to Indicate if the number increases or decreases. Could you please help how do I do it? Do i need to create a measure first? it's not allowing me to do it in the conditional formatting. Thank you in advance!!

Hi @Kpiuser ,

Sharing below the measures that I created for this purpose. 

wow = [curr_week_value] - [prev_week_value]

curr_week_value = sum('Table'[Value])

prev_week_value = CALCULATE(SUMX('Table', 'Table'[Value]), 'Table'[Week] = MAX('Table'[Week])-1)

Attached the PBI file for your reference

Hi @Kpiuser ,

Have a measure created that will return the WOW Number difference. Use this measure to set up the conditional formatting for the week values measure like shown below

Logic for wow is as follows

wow = [curr_week_value] - [prev_week_value]

Hello Thesjeswar, Thank you so much for the idea. It's really helpful. However, could you please teach me how did you structure the week on week dax measure? I totally got the logic but my measure is not showing the correct result.
