TMA 策略

TMA 策略利用多条平滑移动平均线和 K 线形态，在 200 周期趋势方向上交易。它结合 3 线打击和吞没信号，并可选地使用交易时段过滤。

详情

  • 入场条件：在 EMA(2) 高于 SMA(200) 时出现看涨吞没或三连阴转阳；在 EMA(2) 低于 SMA(200) 时出现看跌吞没或三连阳转阴，并通过可选的时段过滤
  • 多空方向：双向
  • 出场条件：EMA(2) 与 SMA(200) 交叉
  • 止损：无
  • 默认值：
    • CandleType = 5 分钟蜡烛
    • FastLength = 21
    • MidLength = 50
    • Mid2Length = 100
    • SlowLength = 200
    • UseSession = false
    • SessionStart = 08:30
    • SessionEnd = 12:00
  • 筛选：
    • 类别: 趋势
    • 方向: 双向
    • 指标: SMA, EMA
    • 止损: 无
    • 复杂度: 中等
    • 时间框架: 日内
    • 季节性: 否
    • 神经网络: 否
