Hull Trend1
Download script
This tool is designed to provide traders with a visual representation of market trends by utilizing the Hull Moving Average (HMA) logic. Unlike standard moving averages that can sometimes lag behind price action, this script focuses on smoothing out price fluctuations while maintaining high sensitivity to recent market changes.
How the Logic Works
The script operates through a multi-step calculation process to determine the current trend direction:
1. Data Processing and Smoothing The indicator begins by calculating a series of weighted moving averages. It takes a portion of the requested period (half of the main period) and compares it against the full period. By subtracting the larger average from twice the smaller one, the script creates a unique data set that highlights the "velocity" or momentum of price movement.
2. Hull Trend Calculation The script then applies a secondary smoothing pass on this processed data. This involves taking the square root of the primary period to determine the final smoothing factor. The result is the "Hull Moving Average"—a curve intended to be much more responsive to sudden price turns than a conventional moving average would be.
3. Trend Identification and Visual Cues The core logic compares the initial processed data against the final Hull Moving Average:
- Bullish Sentiment: When the initial movement exceeds the smoothed trend line, the script identifies an upward bias.
- Bearish Sentiment: When the initial movement falls below the smoothed trend line, it identifies a downward bias.
4. Visual Output To make this information easy to read on a chart, the script automatically plots the price highs and lows based on these conditions. It effectively "colors" the trend by highlighting the boundaries of price action; when the trend is up, it focuses on the high-side data, and when the trend turns down, it flips to highlight the low-side data.
Summary for the User
The primary goal of this script is to filter out market "noise." By using the Hull Moving Average logic, it provides a cleaner look at where the price is heading, helping you identify whether the current momentum is leaning toward a breakout or a retracement without the significant delay often found in traditional technical indicators.
