Average Charges Per Day

[kroberts13]

I am trying to calculate average charges per day of the month. So for example I need to look back 12 months to get the average charges on each day. On the 1st, I need to calculate the average charges for the previous 11 months on the 1st. I need to do that every day. I need that to be rolling for the month. Meaning, If the average on the 1st of the month is $3,000 and the average of day 2 is $4,000. I need day 2 to show $7,000.

This is how charges are calculated....   Sum({$<[DETAIL_TYPE] = {1,10}>}AMOUNT)

Would you be able to share few rows of data with the output you expect from it? or a sample?

What is the expected output?

That is what I currently have in Excel, but it would be a lot of manual work to update the Excel file for Qlik every day. That is what I am trying to get in Qlik. IF it is possible to get charges (Sum({$<[DETAIL_TYPE] = {1,10}>}AMOUNT) averaged out for the specific day of each month looking at the last 12 months that would be great.
