增强型 BarUpDn 策略

该策略结合布林带与趋势确认，寻找向上或向下跳空的 K 线。上涨趋势中出现向上跳空的看涨 K 线时做多；下跌趋势中出现向下跳空的看跌 K 线时做空。退出通过基于 ATR 的止损和止盈实现。

详情

  • 入场条件：
    • 多头：看涨 K 线向上跳空，收盘价高于趋势均线且高于布林带下轨。
    • 空头：看跌 K 线向下跳空，收盘价低于趋势均线且低于布林带上轨。
  • 多空方向：双向。
  • 离场条件：
    • 价格触及基于 ATR 的止损或止盈（1.5× ATR）。
  • 止损：使用 ATR 计算的止损和止盈。
  • 默认参数：
    • BbLength = 20
    • BbMultiplier = 2
    • MaLength = 50
    • AtrLength = 14
    • AtrMultiplierSl = 2
    • AtrMultiplierTp = 3
  • 筛选器：
    • 类别：趋势跟随
    • 方向：双向
    • 指标：布林带、SMA、ATR
    • 止损：有
    • 复杂度：低
    • 时间框架：任意
    • 季节性：无
    • 神经网络：无
    • 背离：无
    • 风险等级：中等
