A trading halt is a temporary pause in trading on a market, during which no new orders are matched while a result, an ambiguity, or a technical issue is resolved.

A trading halt is a temporary stop on trading in a particular market. While it is in place, the order book is frozen for that market, so no new buy or sell orders are matched. The market still exists and your position still exists, but you cannot trade in or out of it for the duration. A halt is a pause, not an outcome, and it ends either when trading resumes or when the market moves on to settlement.
Platforms use halts for several reasons. A common one is that the result is about to become known, or has just become certain, and continued trading on a foregone conclusion would serve little purpose and could invite manipulation. Another is ambiguity, where information about the outcome is unclear or contested and the platform pauses to avoid trading on a false signal. Halts can also follow a dispute over how a market should resolve, or a technical fault that needs to be fixed before trading is safe to continue.
The most important practical consequence is that a halt removes your ability to exit. People often assume they can always sell a position whenever they want, but a halt is exactly the moment that assumption breaks. If a market is halted just as news breaks, you are locked in at whatever happens next, with no chance to take a profit or cut a loss until trading reopens or the market settles. That is a real risk to understand before you trade, not after.
A halt is governed by the platform rules, which set out when a market can be paused and what happens during and after. Because these rules differ between venues, the only reliable way to know how halts work where you trade is to read that platform documentation. The rules also describe how a halted market eventually resolves, including what occurs if the underlying event is cancelled or cannot be settled fairly, in which case some venues void the market and return stakes.
It helps to keep a halt in proportion. By itself, it does not mean your money is gone, and it does not decide the result. What you ultimately receive depends on how the market resolves under its rules, not on the pause. Still, the fact that trading can stop is a useful reminder that liquidity is not guaranteed and that the ability to exit a position is a privilege the market grants, not a right you always hold.
Suppose you hold a contract and a result is expected at a set time. As that moment approaches the platform halts the market, freezing trading. You cannot sell during the halt. When the outcome is confirmed, the market does not reopen for trading but proceeds to settlement under its rules, paying the correct side. The halt simply marked the point where trading stopped and resolution began.
Illustrative only. A general description of how a halt can work, not a description of any specific platform or a prediction.
A halt can lock you into a position exactly when you most want out, so never assume you can always exit on demand. Trade in a size you could hold through to settlement. 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.

It is a temporary pause in trading on a market, during which no new orders can be matched. A platform may halt a market while a result is pending, when information is unclear, or to deal with a technical or rules issue.
Usually no. While a market is halted you generally cannot trade in or out of it, so you are locked in until trading resumes or the market resolves. This is a reason not to assume you can always exit a position on demand.
Common reasons include a result becoming imminent or certain, ambiguity about an outcome, a dispute over resolution, or a technical fault. The platform rules describe when halts can happen, so read them before trading.
Not by itself. A halt is a pause, not a result. The market may resume or proceed to settlement under its rules. What you ultimately receive depends on how the market resolves, not on the halt alone.
