Symbol List Settings
The Symbol List is the list that contains the Most Recently Used symbols. A Symbol List can be found in the Standard chart window, the Options Chain, and Market Depth windows, as well as in the eSignal Toolbar. This last list is called Symbol Linking List.
Editing the Symbol List
To edit the Symbol List, right-click the mouse inside the Symbol List Box and you will get a dialog box with the following 'Edit Symbol List'. Move the cursor inside that box and left-click the mouse. The following window will open.
The Lock Symbol List allows you to lock the list of symbols to prevent new symbols to be added to the list. Setting up the Lock Symbol List, still allows you to type symbols in the Symbol Link Drop-down and view those symbols in charts without adding them to the list.
