How Does the Order Book Work?

The order book is where all buy and sell orders placed for a specific asset are listed. It not only shows the prices buyers and sellers are willing to accept but also displays the quantity available at each price level.

  • Sell Orders (Asks): Usually listed at the top of the order book. The lowest priced sell order is labeled “Sell 1” or “Lowest Ask.”
  • Buy Orders (Bids): Shown at the bottom of the book. The highest priced buy order is labeled “Buy 1” or “Highest Bid.”

This structure allows market participants to monitor supply and demand dynamics in real time.

Order Matching Principles

On Gate TR, order matching follows two main rules:

  • Best Price Priority: For buying orders, the highest price gets priority. For selling orders, the lowest price gets priority.
  • First Come, First Served: If there are multiple orders at the same price, the one placed first is executed first.

For example, if an order at your price level is filled but yours isn’t, it means someone placed the same-priced order before you.

Order Matching by Order Type

Orders placed on Gate TR are handled differently depending on the order type.
Market Order:
When a user places a market order with the intent to execute immediately at the best available price, the system matches the order with the best opposing order in the book (lowest ask or highest bid). Once matched, the order book and price data are updated accordingly.
Limit Order:
When a user sets a specific price to buy or sell, a limit order is placed. The system looks for a matching or better counter-order. If found, the trade executes and the order book is updated. If not, the order is added to the book and waits until it’s matched or canceled by the user.
