Market Orders

Create a PDF of this page to save or print.

A Market order is an order to buy or sell at the market bid or offer price. A market order may increase the likelihood of a fill and the speed of execution, but unlike the Limit order a Market order provides no price protection and may fill at a price far lower/higher than the current displayed bid/ask.


The Reference Table to the right provides a general summary of the order type characteristics. The checked features are applicable in some combination, but do not necessarily work in conjunction with all other checked features. For example, if Options and Stocks, US and Non-US, and Smart and Directed are all checked, it does not follow that all US and Non-US Smart and direct-routed stocks support the order type. It may be the case that only Smart-routed US Stocks, direct-routed Non-US stocks and Smart-routed US Options are supported.

Market Orders example

Symbol XYZ is currently trading at $33.96 - $34.00. You want to buy 300 shares of XYZ right away regardless of price. Create a BUY order, then select MKT in the Type field to specify a market order. Use SMART as the order destination to help ensure best price execution. The word MARKET appears in the Lmt Price field to show that you are willing to buy at the current market price. Submit the order, which is filled at the prevailing market price.
