In trading, TIF stands for time in force, the instruction attached to every order that tells your broker how long to keep it working before automatically canceling it. It’s a dropdown on your order ticket, and its job is to control the lifespan of your trade — from a few milliseconds to several months. Most platforms default to a single-day setting, so if you want anything else, you have to change it yourself before submitting.
TIF matters most on limit orders, where your target price may not be available right away and the broker needs to know how long to wait. On a plain market order that fills instantly, the setting is largely academic.
The Main TIF Options
Day
A Day order is the standard setting on virtually every brokerage platform. It stays active from the moment you place it until the end of the current regular trading session, which runs from 9:30 AM to 4:00 PM Eastern Time on the NYSE and Nasdaq.1NYSE. Holidays and Trading Hours If it hasn’t filled by the closing bell, the system cancels it automatically. You won’t come in the next morning to find it unexpectedly executed at a price that no longer makes sense.
Good ‘Til Canceled (GTC)
A GTC order stays on the books until it either fills or you manually cancel it.2U.S. Securities and Exchange Commission. Good-Til-Cancelled Order This is the setting to use when you have a target price and you’re willing to wait for the market to come to you. Want to buy a stock at $45 while it trades at $48? A GTC limit order sits patiently until either the price drops to your level or you cancel it.
Despite the name, GTC orders do not last forever. Brokerages impose their own maximum durations, and the range varies. Some cap GTC orders at 30 to 60 days; others allow up to 180 calendar days or longer.3Nasdaq. Good Til Cancelled Order GTC Definition Check your broker’s specific policy. If your order quietly expires after 60 days and you assumed it was still working, you could miss your price entirely.
Corporate actions create another trap. When a company announces a stock split, reverse split, or special dividend, brokers typically cancel open GTC orders on that security. The logic is straightforward: if a stock splits 2-for-1 and your limit buy was set at $90, executing at that price post-split would be wildly wrong. Brokers handle the cancellation automatically but do not always send a prominent alert, so check your open GTC orders after any corporate action.
Good ‘Til Date (GTD)
A GTD order lets you pick the exact date your order expires, and some platforms let you set a specific time on that date. This sits between the one-day lifespan of a Day order and the open-ended nature of GTC, giving you precise control over the window.4FINRA.

GTD is useful when a known event is coming up. Say a company reports earnings next Thursday and you want to buy on any pre-earnings dip, but you don’t want the order lingering after the report changes the picture. Set the GTD expiration for Wednesday afternoon and the order works through the window you care about, then dies before the earnings volatility hits.
Immediate or Cancel (IOC)
An IOC order tells your broker to fill whatever quantity is available right now and immediately cancel the rest. If you place an IOC order for 1,000 shares and only 600 are available at your price, you get the 600 and the remaining 400 are gone. There is no second attempt. This works well when you want exposure quickly but can accept a smaller position than planned.
Fill or Kill (FOK)
A FOK order is the all-or-nothing version. The entire quantity must fill in a single transaction, or the whole order is canceled.5U.S. Securities and Exchange Commission. Fill-Or-Kill Order If even one share of your 1,000-share order cannot be filled at the specified price, you get nothing. Traders use FOK when partial fills would break their strategy, such as hedging a large options position where 600 shares would not provide the needed coverage.
A related instruction is All-or-None (AON). Like FOK, it requires the full quantity to fill with no partial execution. The difference is timing. A FOK order that cannot fill instantly is canceled on the spot, while an AON order will sit and wait for the full quantity to become available. FOK is essentially AON with a very short fuse.
Extended Hours and Auction-Only Settings
Beyond the core options, a few specialized TIF designations exist for trading outside the regular session or during exchange auctions.
Regular trading runs from 9:30 AM to 4:00 PM ET, but many brokerages offer pre-market and after-hours sessions that extend the window in both directions.1NYSE. Holidays and Trading Hours To participate you usually need a specific TIF designation, often labeled EXT. A standard Day order will not route to extended sessions. Extended hours orders almost always require a limit price, because thinner liquidity and wider spreads make market orders dangerous during these hours. Some platforms offer hybrid designations like GTC+EXT, which keep an order working across regular and extended sessions until filled or canceled.
Two auction-only categories cover the open and close. An Opening Only (OPG) order participates exclusively in the opening auction and is canceled if it does not fill there. Market-on-Close (MOC) and Limit-on-Close (LOC) orders work the same way for the closing auction: MOC fills at whatever the closing price turns out to be, and LOC fills only if the closing price meets your limit. Both have submission cutoffs before the close, after which cancellations and modifications are heavily restricted.6NYSE. NYSE Closing Auction – Timing Shifts and Marketability Trends
Why TIF Matters More for Limit Orders Than Market Orders
Here is the practical reality that trips up newer traders: TIF is almost irrelevant for market orders. A market order executes at the best available price the moment it hits the exchange during regular hours. Whether you set it to Day or GTC makes no functional difference. It fills immediately and the TIF instruction never comes into play.
TIF becomes critical on limit orders, because a limit order only fills at your specified price or better. If the market is not at your price when you submit, the order sits on the exchange waiting, and that waiting period is exactly what TIF controls. A Day limit order gives the market one session to reach your price. A GTC limit order gives it weeks or months. Choosing the wrong TIF on a limit order means either cutting your window too short or leaving stale orders on the books long after your original reasoning has expired.
Queue Position: A Hidden Reason to Care About TIF
Exchanges fill orders using price-time priority. At any given price level, the order that arrived first gets filled first, which gives resting orders a direct advantage over newer arrivals.
Place a GTC limit order to buy at $50 on Monday, and suppose another trader submits a Day limit order at the same $50 on Wednesday. When a seller shows up at $50, your order fills first. The Monday timestamp puts you ahead in the queue. That is one of the less obvious reasons traders use GTC orders, and it also explains why canceling and re-entering an order at the same price can work against you: you go to the back of the line each time.
Setting TIF When You Place an Order
On most brokerage platforms, the TIF field is a dropdown near the price and quantity inputs on the order ticket. The default is almost always Day, so if you want GTC, GTD, IOC, or any other duration, you have to actively change it before submitting. Forgetting this step is one of the most common order entry mistakes. You intend for an order to stay active for weeks, and it quietly expires at 4:00 PM because you left the default in place.
Selecting GTD typically opens a calendar picker for the expiration date, and some platforms add a time selector for intraday expiration. For extended hours, look for a separate session selector or an additional TIF option, since not every platform labels these the same way.
Once you confirm the order, the broker routes it to the relevant exchange or market maker and is obligated to seek the best available execution while it remains in force.7FINRA. FINRA Rules 5310 – Best Execution and Interpositioning When the TIF condition triggers, whether that is the end of the day, your chosen date, or the instant check for an IOC, the system removes any unfilled portion automatically. Your transaction history will show whether the order was filled, partially filled, or expired, so you can verify the TIF instruction did what you wanted.
