Formula and components

An EMA-centered envelope whose width is based on Average True Range.

Middle = EMA; Upper/Lower = EMA ± multiplier × ATR.

How it works

The indicator transforms price, range, or volume observations over a selected lookback. Shorter settings react faster but create more noise; longer settings respond more slowly and emphasize the underlying regime. Always compare the reading with price structure and timeframe.

How to read it

Channel slope describes trend while width describes range expansion. Persistent closes near one channel can indicate directional strength.

Confirmation checklist

Compare the current range with its own history and distinguish expansion from direction. Volatility can increase during both advances and declines.

Limitations and false signals

Multiplier and lookback choices materially change signals, and repeated touches are normal in strong trends.
