5 EMA 无触摸突破策略

5 EMA 无触摸突破策略等待一根完全位于 5 周期 EMA 一侧的K线。当价格随后突破该K线的极值时，策略按突破方向入场。止损放在该K线的另一端，止盈设为风险的倍数。

详情

  • 入场条件:
    • K线最高价低于 EMA → 准备做多；突破该最高价时入场。
    • K线最低价高于 EMA → 准备做空；跌破该最低价时入场。
  • 方向: 多/空。
  • 出场条件:
    • 止损设在信号K线的极值。
    • 目标为 RewardRisk × 风险。
  • 止损: 有。
  • 默认参数:
    • EmaPeriod = 5
    • RewardRisk = 3.0
  • 过滤:
    • 分类: 突破
    • 方向: 多/空
    • 指标: EMA
    • 止损: 有
    • 复杂度: 低
    • 周期: 5 分钟
    • 季节性: 无
    • 神经网络: 无
    • 背离: 无
    • 风险等级: 中
