RangeFilter FREE is a lightweight adaptive price filter indicator designed to provide a clean, noise-free trend structure by using dynamic volatility-based bands. It employs the Average True Range (ATR) to calculate upper and lower adaptive bands that adjust according to market volatility. The filter moves in a “step style” manner, updating only when price crosses these bands, which helps identify clear trend direction and filter out price noise without repainting.

This simplified version focuses on core functionality with a single adjustable parameter (Period), making it suitable for all symbols and timeframes, particularly effective on M15, H1, H4 charts, and cryptocurrency markets. Key uses include spotting volatility expansion and compression, detecting breakouts when price moves outside the adaptive bands, and serving as a stable foundation for manual or automated trading strategies.

The indicator package includes the indicator file, a default preset (Period 70), a short user guide, and support with updates. RangeFilter FREE serves as an introduction to the more advanced RangeFilter PRO+ suite, which adds features like trend clouds, buy/sell signals, smart stop-loss engines, multi-timeframe filters, alerts, and auto-trade-ready logic.
