It offers a wide range of tools including parallel and extended channels, pennants, AB=CD and ratio tools, Fibonacci retracement with multi-color zone fills, Fibonacci fan, Gann fan and grid, regression channels with standard deviation-based deviation, and a one-shot ZigZag engine. All drawing tools are accessible via an intuitive menu panel that supports customizable offsets, color themes, and button styles. The tool automatically refreshes objects after timeframe changes, maintains correct layering order, and preserves fan levels and color consistency.
