HalfTrend + Trend Ali

This indicator combines the structural logic of the HalfTrend system with a trend filter built on the Hull Moving Average to provide a clearer view of potential market turning points.
The HalfTrend method reacts to price extremes using adaptive deviations, offering a dynamic representation of local highs and lows. By integrating a Hull MA trend filter, the script focuses only on signals that appear in harmony with the prevailing directional bias, helping reduce noise that may occur during counter-trend fluctuations.

🔹 How It Works

The HalfTrend algorithm tracks price swings using amplitude-based detection and ATR-derived channel deviation.

A trend switch is detected when price moves beyond the boundaries of the current swing structure.

The Hull Moving Average acts as a fast-reacting trend reference. Only signals that align with the Hull direction are highlighted.

To maintain clarity and avoid clustered notifications, the script displays only one signal per confirmed trend phase.

🔹 What the Signals Represent

Buy signals appear when the HalfTrend structure shifts upward and the Hull MA confirms an uptrend.

Sell signals appear when the structure shifts downward and the Hull MA confirms a downtrend.

Both signal types include optional alerts for traders who want to be notified immediately when conditions change.

🔹 Purpose

This tool is intended for traders who want to observe structural trend shifts together with a clean and responsive trend filter. It does not attempt to predict the market; instead, it highlights moments when short-term reversals and broader trend direction are aligned.

🔹 Notes

The indicator does not repaint the signals once confirmed.

It can be applied to any market or timeframe.

Users may combine it with their own risk management or additional confirmation tools.
