Four Digital Filters for Trend Analysis on Price Charts

Summary

The document introduces four digital filters intended to appear directly on a price chart: the Fast Adaptive Trend Line (FATL), Slow Adaptive Trend Line (SATL), Reference Fast Trend Line (RFTL), and Reference Slow Trend Line (RSTL). It describes them as a set but does not explain how they are calculated or how a trader might interpret them.

The material gives no examples, performance evidence, or guidance for combining the lines into a trading method. It is therefore useful as a brief inventory of chart indicators, while providing too little detail to assess their signals, suitable markets, or limitations in practice.

Key ideas

• The chart set contains four digital trend filters.
• FATL stands for Fast Adaptive Trend Line.
• SATL stands for Slow Adaptive Trend Line.
• RFTL and RSTL are reference versions of the fast and slow trend lines.
• The document gives no calculation method or trading rules for these filters.
