Belkhayate PRC BT is a technical indicator implementing a Polynomial Regression Channel (PRC) with three standard-deviation bands. It fits a smooth polynomial regression curve (degree 1 to 4) to the last N bars of price data, providing a center of gravity that reflects recent price trends without the lag typical of moving averages. The three deviation bands, calculated from the regression error's standard deviation, serve as zones indicating price extremes, pullbacks, and mean-reversion opportunities.

This indicator helps traders identify mean zones, expansion phases, and exhaustion points by showing how price oscillates around the regression curve, with outer bands often acting as reaction areas. It is applicable across various markets including Forex, indices, commodities, stocks, and cryptocurrencies, supporting symbols like BTCUSD, EURUSD, GBPUSD, XAUUSD, NAS100, and USDJPY.

Recommended uses include trading pullbacks toward the PRC in trending markets, fading extremes in ranging markets, and monitoring volatility through band width changes. The tool is designed for clarity and practical usability on modern charts, suitable for combining higher timeframes for context with lower timeframes for execution.
