Average, Min and Max using MDX

Hello

I don't know MDX well and I need to quicky come up newCaclculated Members for our Cube for the following requirements:

• average / max / min  balance since:
  • account opened date
  • last year
  • current year
• average between two specific dates

Our dimensional model is as follows:

FactDailySnapshot
DateKey
Balance
...

DimAccount
OpenedDate
...

DimDate
DateKey
...

Does anyone have similar MDX scripts for doing the above calculation?

Thanks in advance.
