Exchange execution in stocks refers to the process by which a trade is executed on a stock exchange. When an investor or trader wants to buy or sell a particular stock, the order is sent to an exchange for execution. The exchange then matches the buy and sell orders and facilitates the trade.
An exchange execution is considered to be a faster and more efficient way of trading stocks as it allows for immediate matching of buy and sell orders and results in the faster settlement of trades. Additionally, many exchanges have a significant amount of liquidity, meaning that there are always buyers and sellers available for most stocks, allowing for trades to be executed at or near the current market price.
Exchanges also provide a level of security and regulation, as they are subject to oversight by regulatory bodies such as the Securities and Exchange Commission.
An exchange execution is also known as "Order-Driven Execution" or "Electronic Execution" which is the most widely used execution method in the stock market today.

Exchange execution refers to the process of completing a buy or sell order on a trading exchange. When a trader places an order, it is routed to an exchange where it is matched with a counter-order, either from another trader or a market maker. Execution determines the price, speed, and success of the trade. It can be affected by factors such as market liquidity, order type (market or limit), and the exchange’s rules. Fast and accurate execution is critical in volatile markets, where prices can change rapidly. Some brokers offer direct market access (DMA), allowing faster execution. Poor execution can lead to slippage, where the final trade price differs from the expected one, potentially reducing profitability or increasing losses.
