I know the ticker I added exists, but the Quotes Box can't find it. How do I add it in?

If the ticker is not found, Stock Rover will ask ‘Would you like to investigate?’ Clicking the link will open an ‘Add Ticker to Stock Rover’ wizard which will allow you to add the ticker by filling out the form. Please note that if the ticker is not in a supported exchange, Stock Rover may have limited information for it. See ‘Which stocks are supported?’ for a list of supported exchanges.
