What is Consolidated Tape?

Key Highlights

  • The Consolidated Tape is a technological system that gathers real-time data from the stock exchange, including information on prices and trading volumes.
  • Each company listed on the stock exchange is recognized by its unique ticker symbol.
  • The trading volume signifies the total number of shares traded.
  • Real-time market assessment involves comparing current stock prices with the previous day's closing prices.

Consolidated tapes are electronic systems designed for the real-time transmission of current prices and volume activity across all stocks listed on various exchanges. Functioning through online access, the system follows the traditional ticker tape approach employed by many stock exchanges. Given its widespread accessibility, investors often utilize the internet to stay informed about their investments through the consolidated tape feed.

This resource is commonly employed for reporting on trading conditions, with cable networks providing stock activity updates relying on the consolidated tape as a primary source of information. Similarly, websites offering tips and advice for investors frequently use the consolidated tape to provide up-to-the-minute stock reports. This approach allows investors to keep track of trading volume through various portals that access the information carried by a consolidated tape. Consolidated tapes continuously report the activity of securities listed on the New York Stock Exchange and regional stock exchanges participating in the exchange. A similar setup is employed by the American Stock Exchange (AMEX), reporting securities traded on AMEX proper and other participating markets and exchanges. This combined detail proves beneficial for investors with diverse investments. The data on a consolidated tape can originate from various sources, including securities exchanges, market centers, electronic communications networks, and third-market brokers or dealers. The comprehensive level of detail encompasses a wide range of securities and investment types.

In terms of format, the structure of information reported on a consolidated tape is no more challenging to understand than reading performance ratings in the financial section of a daily newspaper. The key distinction lies in the consolidated tape's provision of the most current information available, with ongoing updates released throughout the trading day.

The Consolidated Tape operates through a structured process managed by critical entities. The New York Stock Exchange (NYSE) oversees Network A, while Network B is under the management of the American Stock Exchange. Registered market centers and exchanges adhere to the Securities and Exchange Commission (SEC) regulations in this well-organised system. They meticulously submit their quotes and trade data to a central consolidator, ensuring a streamlined and unified compilation of stock market information. This centralization enhances transparency and accessibility for investors, providing a comprehensive snapshot of stock prices and transactions across different exchanges.

This central consolidator is a hub, receiving data from various market centers and exchanges. The data is then channeled into the Consolidated Tape System (CTS) and the Consolidated Quotation System (CQS). These systems process the data streams, ensuring a standardized format and validating the information against the database. Subsequently, the data undergoes cross-verification with input from other market centers before being disseminated to recipients globally.

Every trading activity involving securities listed on diverse stock exchanges is meticulously recorded within the electronic system. This comprehensive record allows recipients to access real-time or post-trading-hour information. The Consolidated Tape System maintains a master database that undergoes regular updates with each concluded trade in the stock market, ensuring the availability of accurate and up-to-date information for market participants.

The term "ticker tape" lays the historical groundwork for the modern consolidated tape. Originally, ticker tape referred to the paper strips with stock quotes produced by mechanical machines. These machines earned their name from the ticking sound they made. In the 1960s, electronic ticker tapes replaced their mechanical counterparts, setting the stage for the consolidated tape's introduction in 1976.

The telegraphic ticker tape, created by Edward Calahan in 1867, marked the beginning of this evolution. Thomas Edison, a pioneering American inventor, further enhanced and patented Calahan's design in 1869. During the late 19th century, brokers at the New York Stock Exchange (NYSE) strategically positioned their offices nearby to ensure swift access to the tape, delivered by messengers or "pad shovers." These messengers ran circuits between the trading floor and brokers' offices, with proximity dictating the timeliness of stock quotes—closer offices received more up-to-date information.

The transition from mechanical to electronic ticker tapes in the 1960s marked a significant technological leap, enabling faster and more efficient dissemination of stock quotes. This shift paved the way for the consolidated tape's debut in 1976, revolutionizing the accessibility and consolidation of real-time stock market data.


Investors rely on market data to inform their investment choices, considering factors like price movements, trading volume, and market sentiment. While this information is accessible individually, the challenge lies in consolidating data from various sources efficiently. Gathering such data independently demands significant time and effort, hindering prompt decision-making.

The consolidated tape emerges as a solution, streamlining the process by providing investors with a centralized source for comprehending overall market trends. By leveraging the consolidated tape, investors can make informed decisions, ensuring their investments align with the broader market trajectory.
