Tick Data Inc. has launched Tick Equity Database, a cleansed version of the New York Stock Exchange’s Trade and Quote (TAQ) database of raw historical intraday data for all equities on major and regional U.S. exchanges. The Tick Equity Database, with clean trade and quote data from January 1, 1993, to present, was developed for quantitative investment professionals who require institutional-quality, ready-to-use historical equity data to design, test, and validate trading strategies and order execution services. The service includes Ticker Mapping, which adjusts historical data for corporate actions, including symbol and CUSIP changes, mergers/acquisitions, exchange listing changes, and divestitures. The service was developed under NYSE’s VAP programme, which provides incentives to vendors to work with the TAQ database, according to Mark Schaedel, director of market data for the NYSE.
