The Daily Open Color Zones indicator visually marks the daily open price on trading charts by automatically plotting a horizontal line at this level. It shades the price area above the daily open line in green to indicate bullish zones and the area below in red to indicate bearish zones. These color-coded zones update dynamically with each new candle, providing real-time visual cues about market direction relative to the daily open. The indicator supports all symbols and timeframes, making it applicable across various markets including Forex, cryptocurrencies, and commodities like gold (XAUUSD). Users can customize the line style, thickness, and zone colors to suit their preferences. Designed to be lightweight, it minimizes CPU usage while offering clear intraday reference points commonly used in technical analysis and scalping strategies.
