[GNC] Trading accounts

[David T.]

Kalpesh, 

It is nice to see how a user could use Python to get at this information, but it seems to me that having to supply a list of symbols to the script defeats the point of trying to find those symbols that have secondary namespaces. 

I wonder whether there is a Python analog for "find all securities that are not currencies" that Wm provided in his SQL...
