ATR(21)% EMA Next to Candle

ATR, or Average True Range, is a technical analysis indicator that measures market volatility by calculating the average price movement of an asset over a set period. It does not indicate price direction but shows how much a market is fluctuating. A rising ATR indicates higher volatility, while a falling ATR suggests lower volatility.

Trader Mike Webster, known for his work with the growth-focused CANSLIM strategy developed by William O'Neil, has created his own indicator called the Webby RSI, which incorporates ATR. In this application, the ATR is used to scale a stock's movement relative to its 21-day exponential moving average (EMA). In this case it is based on a percentage.
