SupertrendChannels is a custom overlay indicator that visually identifies dynamic support and resistance zones, entry signals, and trailing stop-loss levels using ATR-based calculations. It plots three lines: an Upper Band (green) serving as dynamic resistance or trailing stop for long trades; a Lower Band (red) acting as dynamic support or trailing stop for short trades; and a Middle Line (purple) used as a mean-reversion level or potential entry point. The bands are calculated by adding or subtracting a multiple of the Average True Range (ATR) from the current candle’s high or low, with selectable smoothing methods applied to the ATR for responsiveness adjustment. Traders use the middle line for entries during consolidations or after crossovers, and the upper and lower bands as adaptive trailing stop-loss zones to secure profits during trends. Unlike traditional Bollinger Bands, SupertrendChannels anchor bands to price extremes plus volatility rather than a moving average, enhancing responsiveness in trending markets and adaptability for both discretionary and algorithmic trading.
