A limit order is an instruction to buy or sell a contract at a specified price or better, which rests in the order book until another trader matches it or you cancel it.

A limit order lets you name the price you are willing to accept. A buy limit order says you will pay no more than a stated price, and a sell limit order says you will accept no less than a stated price. If no one is willing to trade at your price right now, the order rests in the order book and waits. It fills only if and when another participant is willing to meet it, which means a limit order gives you price control but no guarantee that it executes.
The usual contrast is with a market order, which trades immediately against the best available prices. A market order gives you speed and near certainty of filling, but you accept whatever price the book offers, which can be worse than you expected in a thin market. A limit order gives you a known price but accepts the risk that it never fills, or fills only in part if there is not enough size at your level. Choosing between them is a trade off between certainty of price and certainty of execution.
On a prediction market, where many contracts trade lightly, limit orders matter. Posting a limit order can let you buy a little cheaper or sell a little dearer than crossing the spread with a market order, and a book full of resting limit orders is what creates liquidity for everyone else. The cost is patience and the risk that the market moves away from your price before you are filled, leaving you with nothing or with a partial position.
A limit order is a tool, not a safeguard against loss. Setting a careful entry price does not protect you if the contract ultimately resolves against you, and an unfilled order can mean you miss a move entirely. Like everything on these venues, it should be used with a clear understanding that the money at stake is genuinely at risk.
You want to buy a yes contract but the best offer is forty two cents and you think that is a touch high. You place a buy limit order at forty cents. It rests in the order book. If a seller later accepts forty cents, you are filled at your price. If the market instead trades up to fifty cents without dipping to forty, your order never fills and you simply do not have a position.

A limit order controls your price, not your outcome. A careful entry does not stop a contract resolving against you, and any position can lose. Stake only what you can afford to lose, never to chase a loss, and never on borrowed money. If it stops feeling like a free choice, step back.

A market order trades immediately at the best available prices, giving speed but an uncertain price. A limit order names your price and waits, giving a known price but the risk that it never fills or fills only in part.
Because many contracts trade thinly, a limit order can let you buy a little cheaper or sell a little dearer than crossing the spread, and resting orders provide liquidity. The cost is patience and the risk the market moves away from your price.
No. It only controls the price at which you enter or exit. It does not stop a contract resolving against you, and an unfilled order can mean you miss a move. The money at stake is genuinely at risk.
