TAQ Data Queries

Trades and quotes (TAQ) data tables include real-time price quotes and trade prices that are updated frequently during a trading day. Queries against these tables use intraday price and quote fluctuations.

The tick queries are representative of the query workloads generated in pretrade analysis and trade order generation. This selection of possible queries constitutes a reasonable sample test for use in performance and tuning analysis, and also as a template to build a library of queries. You can modify the sample queries to build a native Transact-SQL access layer to present data to computational applications.

TAQ data queries are optimized to run with the RAP sample data in both RAPCache and RAPStore databases.
