[DEM] Donchian Channels Bars

[DEM] Donchian Channels Bars is designed to color-code price bars based on their relationship to Donchian Channel breakouts by comparing short-term and long-term highest high and lowest low levels. The indicator uses two configurable lookback periods (default 1 and 20 bars) and colors bars green when the shorter-period highest high equals the longer-period highest high (indicating an upward breakout or new high), red when the shorter-period lowest low equals the longer-period lowest low (indicating a downward breakout or new low), and purple when neither condition is met. This visual system helps traders quickly identify when price is making significant moves beyond established ranges, with green bars highlighting potential bullish breakouts above recent resistance and red bars highlighting potential bearish breakouts below recent support levels.
