I want to add an instrument (stock) that is not in the NT Database, at least not under that name that I want to add.
My "connectivity provider" is not listed.
1. Why is a symbol map always required ? My stock price data provider knows the stock "ABCDE" and will deliver data. So why map it ?
2. How can I add a symbol if my "connectivity provider" is not listed ?
And could you tell me how many US stocks are in the NT database already ? Is it stored locally and updated from time to time automatically ?
