What is the best setting for ATR?

Could you elaborate on what the ideal setting for ATR, or Average True Range, might be in the context of cryptocurrency trading? ATR is a technical indicator that measures volatility, but the optimal value for traders can vary depending on their strategy and objectives. For instance, shorter-term traders may prefer a tighter ATR setting to capture intraday movements, while longer-term investors might opt for a looser ATR to identify broader trends. Additionally, does the choice of exchange or cryptocurrency pair also influence the optimal ATR setting? Understanding these nuances could help traders make more informed decisions.
