The Average True Range Multiplier (ATRX) is a simple technical indicator that takes the value of the ATR indicator and multiplies it by a user-specified amount.
This indicator is primarily used to set key levels based on historical volatility. The ATR indicator alone measures the historical volatility of the selected instrument, this indicator just multiplies that value to save the hassle of doing that yourself.
