QCL Bollinger Trend Trail
- Indicators
- Version: 1.1
Follow trend direction with a clear, adaptive line directly on your price chart.
QCL Bollinger Trend Trail combines trend detection with integrated volatility filtering to display a trailing reference line. Its two-color presentation helps you identify rising, falling, and unchanged trend conditions without adding a separate indicator window.
The line advances as the trend develops and holds its position when conditions do not support further movement.
Key Features
-
Adaptive trend trail: A dynamic reference line that follows developing price movements.
-
Directional colors: Blue indicates upward line movement; red indicates downward movement. Flat sections retain the existing direction.
-
Integrated filtering: Always active, with an adjustable response period.
-
Optional channel: Display additional upper and lower boundaries for visual context.
-
Simple controls: Five concise inputs with colors managed from the Colors tab.
-
Chart-based display: Keeps trend information alongside price action.
Reading the Indicator
An advancing blue trail indicates upward movement in the reference line. A declining red trail indicates downward movement.
When the line remains flat, its previous direction is preserved. A color change reflects a change in the line’s direction; it is not an automatic entry or exit instruction.
The current candle updates as prices change, so its line position and color can change before the candle closes.
