<br>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. <br>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. <br>For details on specific data vendor symbols, see [[<span style="color: red;">'''LINK'''</span> /102_Builtin_DataSources.html name=""; |Built-in Sources]]

<br>QM has been developed based on those needs, the basic requirements being:
* The program must function with numbers of symbols in tens of thousands
* Rapid data access, which means powerful search, sorting, and selection capabilities
* Simple data backup and restore
* Minimal setup and maintenance effort

<br>Using the keyboard, move the selection pointer to the line containing the symbol. If the selection is not visible, press the '''Down Arrow''' button twice, the selection will be visible on the uppermost symbol; selection with the mouse is simpler and can be achieved by left-clicking the line once.
