The Dynamic Trendline Indicator for cTrader automatically identifies pivot highs and lows to draw adaptive upper (resistance) and lower (support) trendlines on price charts. It projects these trendlines forward using configurable slope calculations based on Average True Range (ATR), Standard Deviation, or Linear Regression approximation. This real-time visualization aids in understanding trend structure and highlights breakout points with clear signals when price crosses the trendlines. Key features include automatic swing detection, adjustable slope multiplier, optional extended trendline display, and customizable colors. The indicator is designed as a lightweight overlay suitable for scalping, swing, and trend trading across various markets including Forex, indices, commodities, stocks, and cryptocurrencies. User inputs allow customization of swing detection lookback, slope calculation method, backpaint mode for historical analysis, and visual preferences. This tool supports manual chart analysis and trade confirmation by identifying trend direction, support/resistance breakouts, and potential trend continuation or reversal zones.
