My account is with TradeKing as the introducing broker to Gain. My login credentials work with both TradeKing and Gain. The account is a live account (not sim), and is not new.
Upon trying to connect NT, I get the error: "Login failed: Unable to log into the GAIN API. Check use name and password. GAIN message: 'Authentication problem. Do I know you? Perhaps we've not been introduced.'"
What do I need to do?
