The order book shows all pending buy and sell orders for the selected asset. It updates in real time via WebSocket and is one of the most important tools for understanding market conditions.

​
Reading the order book

The order book displays two sides:
  • Bids (green) — buy orders waiting to be filled. The highest bid is the best price someone is willing to pay
  • Asks (red) — sell orders waiting to be filled. The lowest ask is the best price someone is willing to sell at
The spread is the gap between the best bid and the best ask. It is displayed in the center of the order book as both a price and a percentage.

​
Columns

The horizontal bars behind each row visualize the relative depth at that price level compared to the rest of the book.

​
Tick size

You can adjust the tick size (price grouping) using the dropdown at the top of the order book. A smaller tick size shows more granular price levels. A larger tick size aggregates orders into wider price bands for a cleaner view.

​
Recent trades

Switch to the Trades tab next to the order book to see the most recent executed trades. Each entry shows:
  • Asset name
  • Side (buy or sell)
  • Fill price
  • Size
  • Timestamp
A tight spread usually means high liquidity and less slippage on market orders. A wide spread suggests lower liquidity — consider using limit orders in that case.
