多头开盘区间突破（ORB）结合枢轴点

当价格突破开盘区间高点且日枢轴点的第一阻力位 R1 高于该高点时，策略做多。止损沿枢轴点跟踪。

细节

  • 入场条件：
    • 开盘区间结束后，如果 R1 在高点之上，突破该高点时做多。
  • 多空方向：仅多头
  • 出场条件：
    • 止损沿枢轴点移动，并在新交易日开始时平仓。
  • 止损：是
  • 默认值：
    • RangeMinutes = 15
    • SessionStart = 09:30
    • MaxTradesPerDay = 1
    • StopLossPercent = 3
    • InitialSlType = Percentage
  • 过滤器：
    • 类别：突破
    • 方向：多头
    • 指标：Pivot Points
    • 止损：是
    • 复杂度：中等
    • 时间框架：任意
