Find last business day of month in power query

Hi All,

Requirement1: 

Source team is generating price files on daily basis to the shared path. My requirement is to get only last business day of each month file in to Power Query & other files to be excluded. If last working of month is holiday then before day file to be selected.

Below highlighted file only to be selected for month of March.

In below example last working day is holiday so prior date file to be selected.

Requirement2:

Also prices of current month should fetch from previous month file. Each file is storing data of forward prices.

 

Some one of you please help me with this requirement in Power Query.

 

Thanks in Advance.
