Market order

From Traderpedia

Definition:
An order to buy or sell immediately at the currently available price.


Sometimes referred to as "at the market", market orders are usually filled immediately by the market maker or exchange.

There will be bid/offer price displayed and a sell order will most likely be filled at the bid price and a buy order will be filled at the ask price. However market orders can be subject to slippage, especially in a fast market.
