I also want to know whether there is a simple way to do that is similar to the query, I by vba to do, can do a function, add a column in a query, use a custom function to get the result, but the amount of data a little more slowly, also can be in the output (when I am with a ListView output) with an array of circulation, the speed is not bad, no matter what method should be sorted first, now I'm using a custom function to sort for date,

Besides VBA, I used a way of generating a query 2, date, the current query and query 2 reproduction query 3, subtracting the amount, but not tested a large amount of data
