Adding can be done manually or from a list, downloaded from the data vendor. | ||
Adding symbols manually is appropriate when the exact symbol name is known and the list of symbols is not available from the data vendor. For instance, with DDE there is no way to download a list, and the user is supposed to know the exact name for the query. | |||
In all other cases, adding symbols manually is <i>not recommended</i>, as parameters in addition to the symbol name may be required by the <i>data vendor</i>. When a symbol is added from a list, provided by the data vendor, all required parameters are set automatically. | |||
