范围过滤器

范围过滤器策略采用平滑的范围计算，并使用固定的止损和止盈。

通过计算平滑范围，在价格周围形成动态带。当价格突破这些带的上方或下方时入场。风险管理使用固定点数的止损和止盈。

详情

  • 入场条件: 价格突破范围过滤器带。
  • 多空方向: 双向。
  • 退出条件: 止损或止盈。
  • 止损: 有。
  • 默认值:
    • SamplingPeriod = 100
    • RangeMultiplier = 3
    • RiskPoints = 50
    • RewardPoints = 100
    • MaxTradesPerDay = 5
    • CandleType = TimeSpan.FromMinutes(5)
  • 过滤器:
    • 类型: 趋势
    • 方向: 双向
    • 指标: Range filter
    • 止损: 有
    • 复杂度: 中等
    • 时间框架: 日内 (5m)
    • 季节性: 无
    • 神经网络: 无
    • 背离: 无
    • 风险等级: 中等
