Market vs Limit Orders
When you place a market order, it is executed as soon as possible at the best possible market price. The market price is determined by the prices that shares are being bought and sold at. As a result, the market price for a company’s shares can change often. Market orders tend to be executed quickly because there is likely to be a buyer, but the price can fluctuate between when an order is placed and when it is filled. Your market order to sell shares will execute immediately at the price that someone else is willing to buy at.
