## Overview

Adaptive KAMA on the main chart and the ER efficiency ratio in a subwindow, attached once. Customize state colors, periods and applied price.

KAMA adapts its smoothing to ER. ER measures directional efficiency from 0 to 1. This indicator supports chart analysis and does not place orders.
