Belkhayate PRC (Polynomial Regression Channel)

1 curve. 3 deviation bands. Clean structure.

Belkhayate PRC is a Polynomial Regression Channel with 3 standard-deviation envelopes.
It helps you spot mean zones, expansion, and exhaustion in a simple way: price tends to oscillate around a smooth regression curve — and the outer bands often act like practical reaction areas.

This release is free, because I want every trader to be able to test it, understand it, and decide if it fits their workflow.

What it does

Polynomial Regression Curve (PRC)

• Fits a smooth regression curve to the last N bars (your Period).
• Degree 1–4: from gentle smoothing to stronger curvature.

Deviation Bands (3 levels)

• 3 envelopes based on the regression error (standard deviation).
• Useful as “zones” for pullbacks, extremes, and mean-reversion conditions.

Why it’s useful

• Trend clarity without laggy MA stacking
  The PRC gives you a clean “center of gravity” for the last Period.
• Structured extremes
  Bands help you judge when price is stretched vs. when it’s back in normal territory.
• Great for context + execution
  Use higher TF for direction/context and lower TF for entries into the curve or band zones.

History / where the idea comes from

This tool is inspired by the classic concept of regression channels used in technical analysis (fitting a regression line/curve to price and building envelopes based on deviation).
The name “Belkhayate” is commonly associated with a popularized version of this PRC-style channel shared across trading communities.
My cTrader implementation is a clean rebuild, focused on stability, settings, and practical usability on modern charts.

Recommended usage

• Trending market: trade pullbacks toward the PRC, manage risk using the nearest band
• Range market: fade extremes (band 2 / band 3) back toward the PRC
• Volatility check: widening bands = expanding volatility / acceleration
