Measure to see historical data from one report that updates everyday.( Complicated)

[Anonymous]

My data has certain tasks with a start date , end date and a status column that reads "completed" or "On Going". I have made a dates table. I want to see how may tasks were open on each day from an excel file that refreshes every morning. The idea is to conditionally format using the following logic: If the task is still open then it will take that into the count and if the task was closed that day means it was open up untill that day so it will take into count as open on the previous day. I dont know how to write this into a measure in power bi. Any Idea?
