Row Counts & Percentages Within Percentages While Applying Filters

Hello, I'm really hoping one of you DAX wizards can help me out. Below is a fabricated dataset (it's for work, but the layout looks like this). 

What I have been able to create:

- A measure which calculates the percentage of unique ID's which were both open and accepted by each date (e.g. the percentage of unique ID's which were both open and accepted for 1/1/2000 is 75%. For 2/1/2000 it is 100%). 

What I'd like: 

- A measure calculating percentage within percentage by program (e.g. of the 100% of IDs which were accepted and open for 2/1/2000, 2 belong to program A and 1 belongs to program D, so the percentages would be 0.66 and 0.33, respectively).

- It needs to be used in a stacked barchart (if possible). What the end result should be is a measure which, when used in a stacked bar plot, will display the overall percentage of ID's which were both open and accepted (this needs to be the height of the barchart, as that's a major requirement...a 100% stacked barchart is a no-go from mgmt) by date, as well as relative percentages by program within each of those bars. The first plot in this link is what the end result should look like: https://blog.coupler.io/power-bi-stacked-bar-chart/#How_to_show_percentage_in_a_stacked_bar_chart_in_Power_BI 

Having to pre-filter by looking for open and accepted values seems to be making this harder (though it could also be a misunderstanding of DAX in general).

I appreciate the help!
