Consolidated Tape Association
The Consolidated Tape Association (CTA) oversees the dissemination of real-time trade and quote information (market data) in New York Stock Exchange (NYSE) and American Stock Exchange (AMEX) listed securities (stocks and bonds).

The Plans were filed with and approved by the Securities and Exchange Commission (SEC) in accordance with Section 11A of the Securities Exchange Act of 1934. Since the late 1970s, all SEC-registered exchanges and market centers that trade NYSE or AMEX-listed securities send their trades and quotes to a central consolidator where the Consolidated Tape System (CTS) and Consolidated Quotation System (CQS) data str ...

Database
In computing, a database is an organized collection of data stored and accessed electronically. Small databases can be stored on a file system, while large databases are hosted on computer clusters or cloud storage. The design of databases spans formal techniques and practical considerations, including data modeling, efficient data representation and storage, query languages, security and privacy of sensitive data, and distributed computing issues, including supporting concurrent access and fault tolerance. A database management system (DBMS) is the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS software additionally encompasses the core facilities provided to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a database system.

Late Trading
Late trading is trading that executes after the market closes, while charging the share price of when the market was still open. This form of trading may be illegal, and is distinct from official after-hours trading. Mutual funds In the mutual fund context, ''late trading'' involves placing orders for mutual fund shares after the close of the stock market, 4:00 p.m for the New York Stock Exchange, but still getting that day's closing price, rather than the next day's opening price. The price of mutual funds is usually set only once per day, so intraday prices are not applicable. Controversy In the United States this practice is illegal under SEC rules but many mutual fund managers appear to have allowed exceptions for certain hedge funds and other favored investors who were able to obtain that day's price, notwithstanding that their orders were received after-hours.

Timestamp
A timestamp is a sequence of characters or encoded information identifying when a certain event occurred, usually giving date and time of day, sometimes accurate to a small fraction of a second. Timestamps do not have to be based on some absolute notion of time, however. They can have any epoch, can be relative to any arbitrary time, such as the power-on time of a system, or to some arbitrary time in the past. The term "timestamp" derives from rubber stamps used in offices to stamp the current date, and sometimes time, in ink on paper documents, to record when the document was received. Common examples of this type of timestamp are a postmark on a letter or the "in" and "out" times on a time card. In modern times usage of the term has expanded to refer to digital date and time information attached to digital data. For example, computer files contain timestamps that tell when the file was last modified, and digital cameras add timestamps to the pictures they take, recording th ...
