General: How to omit QuoteCenter symbol prefixes In order to enter a symbol without prefixing "us;" to it, click on the flag at the bottom of QuoteCenter and set the default country and vehicle class. If these are set to US and Corporate Class, you do not have to enter a prefix. e.g., typing SPX or us;SPX will give the same thing; typing '@ES.1' or 'us@ES.1' and get the same thing.
