What Is Time and Sales?
Time and Sales, also called the "tape," is a real-time record of every individual trade executed for a particular security on an exchange. Each entry displays the exact time of the trade, the price at which it was executed, and the number of shares or contracts traded. This data feed is essential for active traders and market analysts who need to understand the flow of actual transactions rather than just bid-ask quotes. By analyzing time and sales data, traders can identify patterns such as large block trades by institutional investors, the pace and direction of buying or selling pressure, and whether trades are executing at the bid price (suggesting selling pressure) or the ask price (suggesting buying pressure). Modern trading platforms display this information in a scrolling window, often color-coded to distinguish trades at the bid, ask, or between. While Level II quotes show pending orders, time and sales shows what actually happened — making it a critical tool for reading real-time market sentiment and order flow.
