Hi,
This is the solution that Vince Faller (@vince_faller) posted in June (LINK)
This the formula for moving minimum:
Min( :DATA[Index( Min( Row() - 5 ), Row() )] )
Where :DATA is the data column in your table.
For moving maximum, just create another column with the same formula where "Min" is replaced by "Max"
Best
