Forecasting Stock Prices from the Limit Order Book Using Convolutional Neural Networks

In practice, Order Books are used by traders to watch the fluctuations of the bidding price and the asking price of certain products – currencies, stocks, and so on. Analytically tractable models of order book dynamics were of considerable value, but their development has been hindered by the inherent complexity of limit order markets. As mentioned, you can have a quick review of the current market depth and estimate the filled price of a market order. Besides the last traded price and best bid and ask price, the Order Book reveals important information about market depth. Order books consist of open trades, including market orders, limit orders, stop-loss orders, and trailing stop orders. However, long-term investors often use it to time the market to get the best entry price.

The book updates in real-time, allowing traders to identify market trends, popular securities and make informed investment decisions. They can formulate different strategies using the trading pattern, timing, algorithms and charts, and automatic order matching. With better market depth on exchange B, Ann enjoys a lower trading cost and exerts less price impact on other traders. An order book is a list, typically electronic, of buy and sell orders, including the number of shares to be bought or sold. This helps keep track of the level of interest for a tradable instrument and shows the market depth. An order book is a list of orders that presents different offers from buyers and sellers for a specific security. It shows the prices and volumes that people in the market are willing to buy and sell the security for. The system that matches buy orders with sell orders, called the matching engine, uses the order book to execute trades for participants of the exchange.

An ask is the price sellers are asking for by selling you the asset in question. Table 4 results clearly demonstrate the getTopOfBookBySymSide function takes the least amount of time to return top-of-book, albeit by a very small fraction of a microsecond. However, with some small refinements we can achieve even greater improvements. Using a column of type float as one of the keys in our structures is a point for consideration when deciding on a schema to maintain book state. Floating-point issues aside, in the interest of consistency and ease of reading, the remainder of this white paper will continue to use price as a float. We will use a very basic order-book schema and make the assumption that we deal with one symbol at a time when we receive an update.

In order to solve this, I have changed the component to use inline styles, that is pure CSS, instead of a CSS in JS approach. In other words, my bottleneck was using JavaScript animations, which is a famous reason for reduced performance. The point here is that when re-rendering happens unnecessarily, it reduces the performance of our app. This is exactly what happened to me when I introduced the initial implementation of the DepthVisualizer component. It was using styled-components, that is JavaScript, for the drawing part. Rendering is the process of React asking your components to describe what they want their section of the UI to look like based on the current combination of props and state. StatusMessage is a small component used to display status messages.

In every trade day, the automated or manual high-frequency trading usually happens at the open of stock markets since, in this period, the prices change quickly, and variance is high, which could cover trading fees. Once they place a limit order, the order may have high possibility to be filled; if the filling possibilities computed are different from the real ones, they have to cancel the previous orders to wait the next execution opportunity. So, controlled by Chinese SEC on limit orders’ cancellation, the state of imbalanced order flow dominates the market since the proportion of cancellation is low compared with total limit orders in Chinese stock market. The order flow imbalance , proposed by Cont et al. , is defined as the imbalance between supply and demand at the best bid, and ask prices better explain price changes. Their linear model’s goodness of fit is surprising for high-frequency data with a R-squared of 65% on average across 50 stocks in S&P 500 constituents. In Chinese stock market, the algorithm and high-frequency trading are at most 10 percent in everyday trading volume analyzed by stock exchanges. And the solution of time stamp from limit orders, market orders, or other kinds is correct to 10 milliseconds both in Shenzhen stock exchange and Shanghai stock exchange.

These are the three sources, ordered by which is has the most up-to-date response to the one with potential delays in updates. Each endpoint with IP limits has an independent per minute limit. Endpoints are marked according to IP or UID limit and their corresponding weight value. Responses contain the header X-MBX-USED-WEIGHT-, defining the weight used by the current IP. A Retry-After header is sent with a 418 or 429 responses and will give the number of seconds required to wait, in the case of a 429, to prevent a ban, or, in the case of a 418, until the ban is over. IP bans are tracked and scale in duration for repeat offenders, from 2 minutes to 3 days. Repeatedly violating rate limits and/or failing to back off after receiving 429s will result in an automated IP ban . HTTP 5XX return codes are used for internal errors; the issue is on Binance’s side. It is important to NOT treat this as a failure operation; the execution status isUNKNOWN and could have been a success. There is now a Postman collection containing the API endpoints for quick and easy use.

An order which once placed, must either be filled in its entirety or not at all. Buy orders contain buyer information including all the bids, the amount they wish to purchase, and the ask price.

On a solid crypto exchange with liquid markets, this all takes place in milliseconds. When you observe an order book for a couple of seconds, you’ll see the book is dynamic with numbers constantly moving and updating in real-time. When you see the numbers changing, it means that the buy and sell orders are either cancelled by the traders or they are filled through a process called matchmaking. OutboundAccountPosition is sent any time an account balance has changed and contains the assets that were possibly changed by the event that generated the balance change.

The EXCHANGE_MAX_NUM_ORDERS filter defines the maximum number of orders an account is allowed to have open on the exchange.

So, we lack the trading timestamp of limit orders from Shanghai for computing execution timespan. To ensure saving costs from trading stocks, they will use limit orders as much as possible, and with strict limitation on orders’ cancellation, they should estimate orders’ filling probability more accurately.
