📘 Description

Watch_dog – Moving Averages Strategy is a lightweight trend-monitoring indicator built on three adaptive Exponential Moving Averages (EMAs).
It is designed to help traders identify market structure shifts, momentum changes, and higher-timeframe trend direction, with optional alert support.

The indicator dynamically adjusts its moving-average lengths based on the active chart timeframe, making it suitable for lower-timeframe trading and scalping workflows.
