What is Market Order

What is a Market Order
A market order is a buy or sell order to be executed immediately at current market prices. As long as there are willing sellers and buyers, market orders are filled. Market orders are therefore used when certainty of execution is a priority over price of execution. A market order is the simplest of the order types.

A market order may be split across multiple participants on the other side of the transaction, resulting in different prices for some of the shares. It is the most basic of all orders and therefore, they incur the lowest of commissions, from both online and traditional brokers.
