4C Daily Levels Suite + Premarket High/Low

This '4C Daily Levels Suite + Premarket High/Low' indicator is a clean way to automatically plot important daily levels including:
Prior Day High
Prior Day Low
Prior Day Close
50% level between Prior High/Low
Today's Open
Today's Premarket Low+High

This Daily Levels indicator is unique in its ability to:
-Plot all of the daily level PLUS premarket high/low levels (extended hours must be turned ON)
-Can hide past days levels, only plotting levels on the current day, to keep chart cleaner
-Can extend line levels right or fullscreen
-Plots the level price at each level on the chart
-Can show/hide price levels labels
-Can add supplemental premarket levels plot to show levels being formed during the premarket time period
-Coded with line.new vs plot so dashed lines are available as a style
-Automatically hides the indicator if the timeframe selected is Daily or greater
