time in force is a special instruction used when placing a trade to indicate how long an order will remain active before it is executed or expires these options are especially important for active traders and allow them to be more specific about the time parameters 
common examples include immediate or cancel ioc or day order basics of time in forcetime in force orders are a useful way for active traders to keep from accidentally executing trades by setting time parameters they don t have to remember to cancel old trades unintended trade executions can be very costly if they occur during volatile market conditions when prices are rapidly changing most active traders use limit orders to control the price that they pay for a stock which means that they set a time in force option to control how long the order stays open while day orders are the most common type of order there are many circumstances when it makes sense to user other order types there are several different types of time in force orders that traders can use some brokers only offer a limited set of order types but active traders often are given more options many brokers use acronyms like day gtc opc ioc gtd and dtc to refer to these orders we look a little more closely at these order types below types of time in force ordersday orders are a popular type of time in force order they are canceled if the trade does not execute by the close of the trading day these are often the default order type for brokerage accounts another type of time in force order are good til canceled gtc orders which are effective until the trade is executed or canceled some common exceptions include stock splits distributions account inactivity modified orders and during quarterly sweeps these can be a useful option for a long term investor who is willing to wait for a stock to reach their desired price point before pulling the trigger sometimes traders might wait several days or even weeks for a trade to execute at their desired price fill or kill fok orders are a third type of time in force order they are canceled if the entire order does not execute as soon as it becomes available often these are used to avoid purchasing shares in multiple blocks at different prices and to ensure an entire order executes at a single price these can be popular during fast moving markets where day traders wants to ensure that they get a good price on a trade a few other order types include market on open moo and limit on open loo orders which execute as soon as a market opens immediate or cancel ioc orders which must be filled immediately or are canceled and day til canceled dtc orders that are deactivated at the end of the day instead of canceled making it easier to re transmit the order later example of time in forcejohn believes that the price of stock abc which is currently trading at 10 will rise but it will take time approximately three months he purchases abc call options with a strike price of 15 and places a good til cancelled gtc order to avoid having the order remain on hold indefinitely he places a limit of three months on the order after three months stock abc s price is still struggling to break past the 12 mark john s order is cancelled automatically
