SmADX
Download script
This technical tool is designed to provide a smoothed and refined view of market trends by processing standard market momentum data. While the original underlying metrics (ADX, +DI, and -DI) are well-known indicators used to measure trend strength and direction, this specific script applies an additional layer of mathematical filtering to make those signals cleaner and more stable for visual analysis.
Core Logic Overview
The script functions by taking three primary streams of market data and subjecting each to a proprietary smoothing process. Instead of displaying the raw, often "jittery" market data, it calculates a weighted average that prioritizes recent price movements while maintaining the context of previous history. This helps in reducing "market noise"—the small, insignificant price fluctuations that can often lead to false signals for traders.
How the Data is Processed
The logic treats each of the three components independently:
- Positive Momentum (+DI): Identifies the strength of upward price movement.
- Negative Momentum (-DI): Identifies the strength of downward price movement.
- Overall Trend Strength (ADX): Measures how powerful the current trend is, regardless of direction.
For each of these three components, the script performs a sophisticated multi-stage calculation. It takes the raw value and passes it through a series of mathematical weights. This "smoothing" ensures that the resulting lines on your chart are more fluid. By applying this specific logic, the tool seeks to highlight the true underlying direction of the market trend more clearly than a standard indicator would allow.
Visual Output
The result is a three-line visual aid displayed in a separate window at the bottom of your trading platform:
- The Trend Strength Line: A primary line showing the overall power of the current market move.
- The Bullish Momentum Line: A dotted line representing smoothed upward pressure.
- The Bearish Momentum Line: A dotted line representing smoothed downward pressure.
By using this logic, the goal is to provide a clearer "picture" of where the market is heading, allowing you to see the prevailing trend with less distraction from minor price spikes.
