AutoFib Breakout 策略

该策略根据最近的摆动高点和低点绘制动态斐波那契扩展，当价格在上升趋势（EMA200）中突破1.618水平时做多。风险通过基于ATR的止损和目标进行管理。

细节

  • 入场条件：收盘价高于1.618扩展并高于EMA200。
  • 多空方向：仅做多。
  • 出场条件：ATR止损或3×ATR止盈。
  • 止损：是，基于ATR。
  • 默认值：
    • EmaLength = 200
    • AtrLength = 14
    • FibLevel = 1.618
    • PivotPeriod = 10
    • CandleType = 5 分钟
  • 筛选：
    • 类别：突破
    • 方向：多
    • 指标：EMA、ATR、Highest、Lowest
    • 止损：是
    • 复杂度：基础
    • 时间框架：日内
    • 季节性：否
    • 神经网络：否
    • 背离：否
    • 风险等级：中
