Liquidity Data Bank (LDB) - CME Group now offers traders a powerful tool for analyzing volume. This in-depth data source reveals a more precise image of market activity. LDB is an application that summarizes and reports trade data by the Customer Trade Indicator (CTI) code* and is used by trading companies to analyze trading patterns. The CTI specifies whether a trade has been executed by a Member trading for their own account, a Clearing Firm trading for its proprietary account, a Member trading for another member, or all others. This data, currently for CBOT products only, is produced every 30 minutes during regular trading hours and every 15 minutes during Electronic Trading Hours. With LDB, you can: Understand which traders are driving the volume and at what prices Find out what type of customers (CTI 1, 2, 3, and 4) are buying or selling over different time frames Discover who is providing liquidity and what prices are trading the highest volume Access intraday updates http://www.cmegroup.com/market-data/datamine-historical-data/ldb.html Anyone using or looking to use Liquidity Data Bank?
