Orders at better prices will execute before orders at worse prices, and orders placed first will execute before orders placed later. However, because orders are matched by searchers as opposed to a deterministic matching engine, there are no priority guarantees. Once an order transaction is signed and broadcasted, there is no way to recall it. In the absence of such cancellation, the deadline parameter https://www.beaxy.com/glossary/gas-price-ethereum/ can be set to the desired expiration of the order. This mechanism is similar to how “time in force” on most TradFi exchanges defines the duration of orders. This complicates order management for traders attempting to maintain multiple outstanding orders. If the orders are specified with the same nonce, n, then any fill invalidates all the remaining orders because they are using a now-invalid nonce.
The order book is also accompanied by a recent history of completed trades in the market. It took me a while to polish it and I still think it could be improved even more. Try switching between the markets and the grouping values multiple times and observe the results. The most interesting part would be the method buildPriceLevels that is used for both halves – bids and asks. It sorts the data, makes the necessary calculations, and passes it to the relevant components for visualizing it. Those are DepthVisualizer and PriceLevelRow I mentioned earlier in this article. In order to decide whether we are adding data to the current state or we should initialize it, we check for a property called numLevels. This is something that comes from the API, the very first time we establish the WebSocket connection.

Order books contain information about the trading activity such as the price, volume, expiry date and whether the order is a buy or sell. When someone else sees your order on the order book, they can submit an order to the DEX, and the smart contract will check if the funds are available for the trade.
