I see where WD is supposed to have access to Delisted Symbols but I cannot find out how to access them. Can you provide a pointer? Thanks!

Sorry, the history of delisted symbols is probably not available during beta testing period. We're in "limited release" phase now.

I read in FAQs of WD that and how delisted symbols are supported, but I can only see 100 symbols of e.g. Nasaq 100 list. How to access the historic delisted symbols of Nasdaq 100?

Currently, users can access the data only for those components of an index (Dow, DAX etc.) which got delisted since they (users) had subscribed (registered) to the service. In this case, once a symbol gets delisted (e.g. ALTR on 2015/12/24) the W-D provider automatically renames it on your disk as per the FAQ i.e. ALTR.20151224.A. As not much has happened in this aspect since 08/27/2016 (when you subscribed to), I guess that there's shortage of delisted symbols which you could access at this moment of time.

As a growth option of W-D, subscribers would have access to the complete historical list of symbols - most importantly with ability to perform their backtesting free from survivorship bias by virtue of supporting methods in Rule- and code-based Strategies.
