1. What is an Order Book?
In cryptocurrency trading, an order book is a dynamic list displaying all active buy and sell orders, sorted by price. Centralized exchanges primarily use this model:
- Makers place orders at varying price levels, recorded in the order book.
- Takers execute trades by matching these orders.
Order books provide real-time market snapshots, including the best bid (buy) and ask (sell) prices.
2. What is Order Depth?
Order depth measures the total volume of orders at each price level. It reveals market liquidity:
- High depth = More liquidity, faster trade execution.
- Low depth = Higher volatility, potential slippage.
Traders analyze depth to gauge execution likelihood and market stability.
3. Key Components of an Order Book
| Component | Description |
|---|---|
| Buy Orders | List of bids from buyers at specific prices. |
| Sell Orders | List of asks from sellers at specific prices. |
| Price | Levels at which assets are offered or requested. |
| Order Quantity | Volume of assets available per price level. |
