I have a connection with IQFeed, and have previously seen this problem with Kinetick connections for stocks. When I try to load a stock symbol (any symbol), I get a message like this:
Error on loading chart data for '<symbol> Default': E,Invalid symbol
Any ideas on why this is happening? Sometimes the tick-based data loads fine, other days it doesn't.
EDIT: This is only for tick-based charts, like second-bars. Minute-based charts are always OK.
