Artificial Intelligence Accelerator 策略

该策略使用比尔·威廉姆斯的**加速/减速振荡器（AC）**构建一个简单的感知器模型。策略提取0、7、14、21根K线的AC值，与可调权重相乘并求和作为信号。信号大于零表示看涨动能，信号小于零表示看跌动能。当信号变号时策略会反向持仓，并在入场价格设置固定止损。

AC源自超强振荡器（AO），即AO减去5周期移动平均，使得策略对市场加速度变化更敏感。

详情

  • 入场条件：
    • 多头：感知器信号 > 0。
    • 空头：感知器信号 < 0。
  • 多空方向：双向，信号翻转时反向。
  • 出场条件：
    • 达到固定止损。
    • 信号穿越零点时反向。
  • 止损：是，按价格单位固定止损。
  • 默认值：
    • X1 = 76
    • X2 = 47
    • X3 = 153
    • X4 = 135
    • StopLoss = 8355
    • CandleType = 1分钟K线
  • 过滤器：
    • 类型：趋势跟随
    • 方向：双向
    • 指标：AC（源自AO）
    • 止损：有
    • 复杂度：中等
    • 时间框架：短期
    • 神经网络：感知器
    • 风险等级：高
