RealBody Donchian Channels

This is an enhancement of the built-in TradingView Donchian Channel indicator.A technical variation of the standard DC, it utilizes candlestick real body data. Instead of using the absolute high and low (shadows) for extreme value calculation, this indicator derives the channel boundaries from the highest Max(Open, Close) and the lowest Min(Open, Close) within the specified length. This approach filters out noise from wicks/shadows, providing a cleaner look at sustained price ranges defined by buying and selling pressure between the open and close.
