Universal Trailing Stop Hedge 策略

本策略展示多种用于保护持仓的移动止损方法。 提供基于 ATR、Parabolic SAR、移动平均、利润百分比和固定点数的移动止损。 入场仅使用蜡烛方向作为示例，主要用于教学。

详情

  • 入场条件：蜡烛收盘价高于开盘价做多，低于开盘价做空
  • 多空方向：双向
  • 出场条件：触发移动止损
  • 止损：根据选择的模式使用 ATR、Parabolic SAR、MA、利润百分比或固定点数
  • 默认值：
    • Mode = TrailingModes.Atr
    • Delta = 10
    • AtrPeriod = 14
    • AtrMultiplier = 1m
    • SarStep = 0.02m
    • SarMax = 0.2m
    • MaPeriod = 34
    • PercentProfit = 50m
    • CandleType = TimeSpan.FromMinutes(5).TimeFrame()
  • 筛选：
    • 分类：风险管理
    • 方向：双向
    • 指标：ATR、Parabolic SAR、SMA
    • 止损：移动止损
    • 复杂度：中等
    • 时间框架：日内
    • 季节性：无
    • 神经网络：无
    • 背离：无
    • 风险等级：中等
