pyiqfeed integration for multiple equities data

[darkknight9394]

Hi, I'm trying to get IQFeed working with multiple US symbols, but got 2 major questions which I'd like to have your input.

1. As I know pyiqfeed requires a DTN password, login, and developer account ID which are inputs to pyiqfeed/service.py FeedService. I am wonder when itnergration is done with backtrader, where should the password.py be placed?

2. I've some initial success but realize there's seems to be a huge delay when the number of stocks exceeds n>15. Want to have you inputs in terms of how to get this working.
