If a market order to sell is executed at $21.35, what will the customer receive?

When a market order to sell is executed, it implies that the seller agrees to sell their shares at the best available price in the market at that given moment. In this case, the execution price of the market order is $21.35. This means that the shares were sold at this price, and the customer will receive the proceeds from the sale, which is directly tied to the execution price.

Consequently, if the market order was executed at $21.35, this is exactly the price at which the shares were sold. Thus, the customer will receive $21.35 per share sold. It is important to understand that market orders guarantee execution but not the specific price, though in this instance, the order was filled at the stated amount.
