Trading Order Types

Order TypeDescription
Market OrderA market order guarantees a fill or execution, but unlike a limit order, a market order provides no price protection. The price at which you actually execute (or fill) the trade can deviate from the last traded price, ending up with a price higher or lower than the market value you have previously seen due to the high volatility of the market or low trading volume of certain securities.
Limit OrderA limit order allows investors to buy and sell securities at a specific limit price or better. Investors often use limit orders to have more control over execution prices. With a limit order, the range of price is specified by the investor, but the order may not be executed at exactly the price specified. It can be executed at a more favorable price than the specified one.
Stop OrderA stop order is an order to buy or sell a stock once the price of the stock reaches a specific price, known as the stop price. When the stock hits your stop price, the stop order becomes a market order. The market order is executed at the best price currently available.
Stop Limit OrderA stop limit order has both features of a stop order and a limit order. When the stock hits a stop price that you set, it triggers a limit order. Then, the limit order is executed at your limit price or better.
