I'm paying a computer geek to interface with Norgate so I'll ask him; my understanding is it is adjusted closes and volume every day going 1 year before the Nasdaq100 started, on every stock ever in the index from the start of the data I could get (1993), forward to now, and the constituent changes, so you can run backtests on price and/or volume or permutations like moving averages, using various look-backs up to a year and various holding periods. I have not found any data sources for earlier than 1993. I haven't verified this yet but it was the goal I gave him to meet and he told he he can. I may be able to get S&P500 changes from the same date. Until in hand I can't promise anything but this is where it stands.
