What is the best way to use ATR?

Could you elaborate on the optimal utilization of Average True Range (ATR) in cryptocurrency trading and finance? ATR, as a technical indicator, measures the volatility of a given asset over a specific period. As a practitioner, I'm interested in how ATR can be leveraged to make informed trading decisions. For instance, how can ATR assist in identifying potential entry and exit points? Additionally, how does ATR correlate with other indicators to provide a more comprehensive analysis? I'm keen on learning how industry experts leverage ATR in their daily trading practices and financial planning.
