- Implied probability
- A common reading of an outcome-contract price. A Yes price of $0.63 is often described as 63% market-implied probability; it is not a promise.
- Outcome contract
- A contract tied to a written question and resolution rule. Read the exact conditions before assessing its price.
- Bid and ask
- A bid is a standing offer to buy; an ask is a standing offer to sell. The difference between the best bid and best ask is the spread.
- Spread
- Gap between best visible buy and sell prices. A wider spread can make entering or exiting more expensive.
- Liquidity
- Amount available to trade near current prices. A market can show a price without enough depth for a larger order at that price.
- Slippage
- Difference between an expected price and average fill price, often caused by limited depth or a fast-moving market.
- Limit order
- Order that states the worst price you accept. It can remain open, fill partly, or not fill.
- Marketable order
- Order that seeks available liquidity immediately. Its fill price can vary with current spread and depth.
- Resolution
- Process used to determine which outcome wins under the market's written rules and stated source.
