An order book is the live list of buy and sell orders at different prices for a market, showing available liquidity at each level.
Understanding order book helps you read prices and manage risk on any prediction market platform.
Example
The order book might show buyers willing to pay 48¢ for 500 shares and sellers asking 51¢ for 300 shares.
Reading depth at each price level helps you judge whether a large order will move the market much before it fully fills.
Why it matters
Knowing how order book works lets you compare markets and avoid costly mistakes when trading.
Practical tip
Before trading, check how order book shows up on the specific platform you use, since interfaces and terminology can vary slightly between exchanges. Reviewing a few live markets is a quick way to see order book in action before risking real funds.
