Overview
Recursive Median Filter calculates the median source value across a specified median length and recursively blends it using a lowpass alpha coefficient derived from the lowpass length input. The indicator plots a single line over price bars, with optional color highlighting that shifts between green and red to indicate rising or falling values.
- Median percentile rank calculation
- Lowpass exponential smoothing filter
- Directional color change visualization
- Customizable median and lowpass lengths
