Trailing Smart Algorithm is a trend-tracking indicator designed for use in any market condition. It employs mathematical algorithms to maintain a trendline that stays synchronized with price movements, minimizing lag common in traditional indicators. The system adapts dynamically to market volatility by calculating step sizes based on the Average True Range (ATR), allowing larger steps in volatile markets and smaller steps in quieter ones.

The indicator operates through three main components:
1. Trend Change Detection: Monitors price to identify significant moves beyond a set threshold (Impulse Trigger), signaling potential trend direction changes.
2. Dynamic Trailing: Moves the trendline step-by-step in the direction of the dominant trend, adapting to current volatility.
3. Volatility Channel: Creates upper and lower bands around the trendline representing normal volatility zones, helping to identify extreme price moves.

Retest signals are provided as visual markers—cyan stars indicate potential bullish bounces on the lower band during uptrends, and magenta stars indicate potential bearish bounces on the upper band during downtrends. Users can customize parameters such as sensitivity to trend changes, maximum step size, and channel width, as well as visual settings like trend colors and channel fill. Alerts for retest signals can be enabled and filtered by trend direction.

This indicator supports visualization and signal outputs based on price levels and volatility, suitable for symbols including BTCUSD and XAUUSD.
