DAX measure for rolling one year calculation

[Anonymous]

Hi all,

I need to create a measure for the following simplified scenario. 

In my data set there is a date column and a value calumn. There is one record per day ( exccluding weekends and hilodays ) in this dataset.

In my visualizaation I have to skip first 252 days (first year ) , and for any given date after that divide the value for that date by the value for the day 252 prior to that date.

example 

Date                                                 Value

5/5/2016 ( start date)             101

5/6/2016                                         99

...

5/5/2017                                          105

5/6/2017                                          103

....

------------------------------------------------------------------------------------------------------------------

My visualtion should display the following .   Please note I don't wnat to show any records prior to 5/5/2017 in the visualization because there is no data for dates prior to   5/5/2016 in the dataset     (Date - Year ago)

5/5/2017                                         1.039    (calculation is : 105/101)

5/6/2017                                          1.040   (103/99)

........  

I hopw I was able to exxplain the requirment clearly. Thank you for you help.
