精调均线策略 (Fine Tuning MA)

策略关注简单移动平均线的斜率。连续两个柱同向运行后，均线反转即触发交易。下行后的上拐做多，上行后的下拐做空，反向信号平掉当前仓位。

该系统由 MQL 专家顾问 "Exp_FineTuningMA" 转换而来，使用标准简单移动平均线代替原始自定义指标。

详情

  • 入场条件: 均线在连续两柱后改变方向。
  • 多空方向: 双向。
  • 出场条件: 反向信号或止损止盈。
  • 止损: 是，百分比。
  • 默认值:
    • MaLength = 10
    • TakeProfitPercent = 1
    • StopLossPercent = 1
    • CandleType = TimeSpan.FromHours(4)
  • 过滤器:
    • 类别: 趋势跟随
    • 方向: 双向
    • 指标: SMA
    • 止损: 是
    • 复杂度: 中等
    • 时间框架: 波段 / 4 小时
    • 季节性: 否
    • 神经网络: 否
    • 背离: 否
    • 风险等级: 中
