An order book chart is a chart visualization representing real-time bids and asks for a specific asset in a trading environment. This Highcharts demo showcases a dynamic order book chart, enabling users to visualize the depth of the market for any given asset. The chart is structured to display two main components: buy orders (bids) and sell orders (asks), each plotted on either side of a central price line, illustrating market depth and price levels at which trades can potentially occur.
