Enhanced Donchian Channel Overlay

This is my first public release of an indicator, free for all to use. There will be a multitude of indicators significantly more complex in the future, still under testing. It's simple purpose is to track highest high in red and lowest low in lime over a specified period of 5 preceding bars by default. The upper and lower banding have independent adjustable period settings. The banding line widths are also adjustable. A smoothable mean line is displayed in olive color and may be disabled by altering the line width to zero. I also included a yellow close line capability disabled by default by it's line width. I presume most people use candles but an occasional few may wish to see a close line plot too. Please provide any feedback/requests as you wish.
