Litecoin 追踪止损策略

Litecoin 追踪止损策略 使用考夫曼自适应移动平均线 (KAMA) 识别多空趋势。KAMA 上升时做多，下降时做空。经过可配置的延迟后，基于百分比的追踪止损用于保护利润。

细节

  • 入场条件：KAMA 方向并在入场之间设置冷却时间。
  • 多/空：双向。
  • 离场条件：追踪止损。
  • 止损：延迟后的百分比追踪止损。
  • 默认值：
    • KamaLength = 50
    • BarsBetweenEntries = 30
    • TrailingStopPercent = 12
    • DelayBars = 50
  • 过滤器：
    • 类别：趋势跟随
    • 方向：双向
    • 指标：KAMA
    • 止损：追踪止损
    • 复杂度：基础
    • 时间框架：中期
    • 季节性：否
    • 神经网络：否
    • 背离：否
    • 风险水平：中等
