Limit order
A limit order is an instruction to buy or sell only at a price you set or better. It protects you from a bad fill, but it does not guarantee that the trade happens at all, because the market may never reach your price.
What a limit order does
The SEC's investor education site defines a limit order as an order to buy or sell at a specific price or better. A buy limit sits below the current price and a sell limit above it. If the market never trades through your level, the order simply stays open or expires.
How it works on a swap venue
On order-book venues a limit order rests on the book until someone matches it. On swap-based venues the mechanism differs. Jupiter's trigger documentation says its price orders are stored off-chain and kept private until the trigger condition is met, then Jupiter handles routing and execution.
That page also carries caveats worth knowing: output is not guaranteed, the pool price at execution may differ from your trigger price, price orders can fill partially, and an expired order leaves funds in a vault that you recover with a cancel flow.
When to use one
Use a limit order when the price matters more than speed, for example when you want to buy a dip at a level you chose in advance, or sell into strength without watching the screen. Use a market order when getting filled now matters more. On thin memecoin pools, a resting order can still be filled at a worse price than you intended if the pool moves sharply, so check the venue's own execution notes.
This is general education about order mechanics, not advice on what price to pick.
Common mistakes
Setting a price too close to the market and assuming it will fill is common. A limit order that sits for days can fill after news you no longer agree with, so cancel orders you have stopped believing in. Another mistake is forgetting that onchain orders may live in a vault or program that needs a separate cancel step before funds return to your wallet, as the Jupiter documentation describes.
Finally, compare any fees on the order itself. Some venues charge nothing extra for resting orders, others charge at fill. Read the fee page before relying on one.
