Good-Til-Cancelled Order

A Good-Til-Cancelled (GTC) order is an order to buy or sell a stock that lasts until the order is completed or cancelled. Brokerage firms typically limit the length of time an investor can leave a GTC order open.  This time frame may vary from broker to broker.  Investors should contact their brokerage firms to determine what time limit would apply to GTC orders.

To understand where and how an order you place with your broker is executed, you should read Trade Execution: What Every Investor Should Know. For more information on the different types of orders you can place when you buy or sell a stock, please read our investor bulletin “Trading Basics”.
