Slow Smoothing Constant is the lower-speed smoothing constant derived from KAMA's declared slow period.

Also known asKAMA slow alpha

Intermediate Formula defined 1 linked topicPublished

Definitions

In plain terms

It bounds the adaptive coefficient toward a more persistent update when efficiency is low.

Technical

The period-to-alpha convention, allowed parameter ordering, precision, and effective version must be explicit.

Scope

Slow describes the parameter bound, not an independent moving average output.

Formula

Slow SC = 2 / (slow period + 1)
LaTeX: SC_s=\frac{2}{n_s+1}

Output unit: ratio

Examples

  • A governed lesson uses Slow Smoothing Constant only with declared inputs, timing, parameters, and edge-case behavior.

Common misconceptions

  • Slow describes the parameter bound, not an independent moving average output.
