Moving Average Area

As a trader, it is much more convenient to draw support and resistance in a form of an area instead of just a straight line. Same thing with moving averages which are often used as dynamic support and resistance. This indicator plot a moving average on the chart in a form of an area. You can customize the size of the band in the options menu.
