hey guys. i was wondering if anyone here has some experience using built up IB historical data for backtesting automated systems. i want to start testing systems with a wider range of assets and types of data beyond bid/ask prices. i am looking to build a database ideally from 2001 to 2007 in order to test on multiple market types. my questions are 1) how is the quality of data obtained through reqHistoricalData? does anyone have any opinions on this in terms of use for backtesting. 2) is it possible to request years worth of futures data from a single contract such that the price always comes from the front month's contract? 3) is it possible to obtain trade prices and volumes on historical data for building market profiles etc? basically a time&sales for the past few years. or is the only way to record them live and wait for enough data to test. thanks for your help.
