FATL: A Fast Adaptive Trend Line from Low-Pass Filtering
Summary
The document introduces FATL, or Fast Adaptive Trend Line, as a chart indicator calculated with a digital low-pass filter. It identifies the indicator as a fast adaptive line and notes that it is displayed as a cream-colored line on a chart. This provides a basic description of the calculation family and visual identification, but does not explain the filter parameters, adaptation mechanism, or how to interpret the line in trading decisions.
No chart, formula, code details, test results, or trading rules are included in the text, and it offers no evidence that the indicator predicts price movements or improves a strategy. The brief description is therefore useful as an orientation to the indicator concept rather than as an implementation or evaluation guide. Traders would need further technical documentation to assess lag, responsiveness, signal behavior, and performance across instruments or market conditions.
Key ideas
- FATL stands for Fast Adaptive Trend Line.
- The line is calculated using a digital low-pass filter.
- The document identifies the plotted line by its cream color.
- It gives no parameters, trading rules, or empirical performance evidence.
