Good till cancel的意思

"Good till cancel" (GTC) is a term commonly used in the context of stock trading and other financial transactions. It means that an order to buy or sell a security will remain in effect until it is either executed or canceled by the investor.

For example, if an investor places a GTC order to buy 100 shares of a particular stock at a specific price, that order will remain active until the shares are bought, the investor cancels the order, or the brokerage firm notifies the investor that the order can no longer be executed due to changes in market conditions or other factors.

GTC orders are useful for investors who want to ensure that their order is executed at some point, even if it means waiting for the market to reach the desired price. They are less likely to result in a partial fill, as the order will remain open until the full quantity is traded. However, GTC orders can also expose investors to greater market risk, as they may be left holding a position that they are no longer comfortable with if market conditions change significantly.
