Fracture

Fracture 将分形突破与平滑移动平均和 ADX 结合，用于在盘整和趋势市场中交易。

细节

  • 入场条件：当 ADX 低于阈值时，若价格也在快速 SMMA 上方/下方，则在最后一个上/下分形处做多或做空。趋势状态下（快速 SMMA 高于/低于慢速线）在价格穿越快速 SMMA 时顺势入场。
  • 多/空方向：多头和空头。
  • 出场条件：利润超过 ATR 与 MinProfit 的乘积时平仓。
  • 止损：基于 ATR 的利润目标。
  • 默认值：
    • CandleType = TimeSpan.FromMinutes(1)
    • AtrPeriod = 14
    • AdxPeriod = 22
    • AdxLine = 40
    • Ma1Period = 5
    • Ma2Period = 9
    • Ma3Period = 22
    • RangingMultiplier = 0.5
    • MinProfit = 1
  • 筛选：
    • 分类：突破
    • 方向：多空皆可
    • 指标：分形、SMMA、ATR、ADX
    • 止损：有
    • 复杂度：中等
    • 时间框架：任意
    • 季节性：无
    • 神经网络：无
    • 背离：无
    • 风险等级：中等
