# Order Book

*Trading & Technical Analysis — Finicade finance glossary*

The order book lists all resting buy and sell orders by price, showing where liquidity sits above and below the current price. Its depth determines how far a large order will move the market. It's also actively gamed: displayed orders can be placed and cancelled to create false impressions of demand, which is what spoofing is and why it's illegal.

**Also known as:** limit order book, depth of market, the book
