常见的 ATR 乘数为 1.5× 至 3×。 A 2×ATR stop is a popular default — it's wide enough to avoid normal price noise but tight enough to limit losses. Use 1.5× for tighter stops on stable stocks, and 3× for volatile stocks or swing trades.
如何设定良好的止盈水平？
将止盈设置在一个能够为您带来有利风险回报比（至少 1:2）的水平。 Use technical analysis — previous resistance levels, Fibonacci extensions, or measured moves — to identify realistic targets. Don't set targets so far away that they're unlikely to be reached.
