Hello! Trading on an exchange involves placing buy and sell orders, which are matched by an algorithm in the order book. The order book lists all open orders for a given asset and is constantly updated in real-time. Factors that can affect the speed and efficiency of trading include network congestion, order size, and market volatility, see
site web. It is important to have a good understanding of the order book and market conditions before placing an order. Good luck and happy trading!
