stelaraX – Ehlers Super Smoother

stelaraX – Ehlers Super Smoother is an advanced smoothing and trend filter designed to reduce noise while preserving responsiveness. Based on a 2-pole digital filter concept by John Ehlers, it produces a cleaner trend line than classic moving averages and can be used to better visualize direction changes without excessive lag.

Core logic

The script implements a 2-pole Super Smoother Filter using exponential and trigonometric coefficients derived from the selected period. It processes the price source through a recursive filter equation to remove high-frequency noise while maintaining smooth directional behavior.

Key principles:

* filter coefficients are derived from the chosen period length
* the Super Smoother is a recursive 2-pole digital filter
* it averages current and prior source values for stability
* the filter output adapts smoothly while reducing short-term whipsaws
* slope direction (rising/falling) is used to determine line color
* an optional EMA reference is included for comparison

Compared to a standard EMA, the Super Smoother typically delivers a smoother curve with less jitter at similar responsiveness.

Visualization

The script plots:

* the Super Smoother line directly on the price chart
* dynamic color changes based on slope direction (bullish/bearish)
* an optional EMA reference line with subtle styling for comparison

This clean overlay helps distinguish true directional drift from noisy fluctuations.

Use case

This indicator is intended for:

* filtering noise to improve trend readability
* detecting cleaner directional shifts via slope changes
* acting as a smooth dynamic support/resistance guide
* filtering entries for trend-following systems
* comparing filter behavior against traditional EMAs

It works particularly well as a foundational trend filter when combined with momentum tools, structure analysis, and AI-assisted chart evaluation.
