An order is considered fully executed when it has traded all of the specified volume. This is known as a filled order, where the buyer and seller have come to an agreement on the price and quantity of the transaction. It is important to understand this concept in finance, as it plays a crucial role in analyzing market trends and making informed investment decisions. As a wise investor, it is essential to keep track of filled orders and their impact on the overall market movement. It is through this understanding that one can potentially maximize their profits and minimize risks in the dynamic world of finance.
