What Is a Good-Til-Canceled (GTC) Order?
Not every trading idea plays out within a single session, and forcing a trader to resubmit the same order morning after morning would be tedious at best. A good-til-canceled order exists to solve exactly that friction.
The short answer
A good-til-canceled, or GTC, order is an instruction to buy or sell a security that remains active across multiple trading sessions rather than expiring at the end of the day it’s placed. It stays open until one of three things happens: the order fills, the trader manually cancels it, or it reaches a broker-set expiration limit, since most platforms don’t allow a GTC order to remain open indefinitely without any cap at all.
How persistence actually works
Once submitted, a GTC order sits with the broker waiting for its price or condition to be met, checked continuously as the market moves during each session it remains open. Unlike a day order, which quietly disappears if not filled by the closing bell, a GTC order carries forward into the next trading day automatically, with no action required to keep it alive. Whether the underlying instruction is a simple market or limit order or something more conditional, this makes GTC a useful duration for a price target that isn’t expected to be reached quickly — a buy order well below the current price, for instance, or a sell order set well above it.
Why brokers still cap how long it lasts
Despite the name, good-til-canceled rarely means truly unlimited in practice. Most brokers impose a maximum number of days a GTC order can remain open before it’s automatically canceled, after which it needs to be resubmitted if the trader still wants it active. This cap exists partly to keep old, possibly stale orders from lingering indefinitely on the books, and partly to prompt traders to periodically reconfirm that an order still reflects current thinking rather than a price target set long ago under different conditions. The specific cap varies by broker and by order type, so it’s worth checking directly with the platform being used rather than assuming a fixed universal number.
Why traders use them
- Set-and-monitor convenience. A target price can be set once instead of resubmitted every session, which suits a trader watching a security they’d like to buy or sell only if it hits a specific level.
- Useful alongside conditional orders. GTC duration is commonly paired with a stop-limit order or a trailing stop order, since the combination lets a trigger sit ready for an extended stretch without daily resubmission.
- Still requires periodic review. Because market conditions and the reasoning behind an order can shift, leaving a GTC order untouched for a long stretch carries the risk that it executes under circumstances that no longer match the original intent.
What to weigh
A GTC order trades the convenience of not resubmitting daily for the responsibility of remembering it’s out there. An order placed weeks ago and forgotten can still execute at a price that made sense at the time but doesn’t reflect the trader’s current view. Treating a GTC order as something to periodically revisit, rather than a fully passive tool, keeps it aligned with its original purpose.
The bottom line
A good-til-canceled order is less about a specific trading strategy and more about matching order duration to how quickly a target price is expected to be reached. For a price target that could take a while, GTC removes the need for daily resubmission, as long as the order isn’t simply left unmonitored until its eventual expiration or execution.
