With octobercms, I have a list of orders. I want to count the number of orders, sales, etc. by filtering the order time, order status, etc. I hope that the data can be changed in real time after filtering.

If I understand you correctly you want to know how to update info on a backend page after you filter the list on that backend page (e.g. to exclude certain orders).
