The number of executed orders.

In Detail views, Orders column is followed by the Total % column, which shows the line item’s percentage of the total number of executed orders. For example, in the Buy or Sell breakdown, suppose there are 60 Buy orders and 90 Sell orders. The Total% of Buy orders would be 40, or 40% of the total number of orders, and the Total% of Sell orders would be 60, or 60% of the total number of orders.
