Enter the levels that are displayed for level based chart drawings into the "Levels" text box.
The levels setting applies to all of the level based chart drawings (e.g. fibonacci levels, etc.), and the levels setting can be set individually for each chart drawing, including drawings of the same type (i.e. different fibonacci drawings can display different fibonacci levels).
If the "Levels" text box is disabled, it means that the levels setting does not apply to the chart drawing that is being configured (e.g. the levels setting does not apply to vertical lines that are displayed on a chart).
