MACD Sentiment Filter

MACD Sentiment Filter 策略基于 MACD Sentiment Filter。

当 its indicators confirms filtered entries 在日内（15m）数据上得到确认时触发信号，适合积极交易者。

止损依赖于 ATR 倍数以及 MacdFast, MacdSlow 等参数，可根据需要调整以平衡风险与收益。

详情

  • 入场条件：参见指标条件实现.
  • 多空方向：双向.
  • 退出条件：反向信号或止损逻辑.
  • 止损：是，基于指标计算.
  • 默认值:
    • MacdFast = 12
    • MacdSlow = 26
    • MacdSignal = 9
    • Threshold = 0.5m
    • StopLoss = 2m
    • CandleType = TimeSpan.FromMinutes(15).TimeFrame()
  • 过滤器:
    • 分类: 趋势跟随
    • 方向: 双向
    • 指标: multiple indicators
    • 止损: 是
    • 复杂度: 中等
    • 时间框架: 日内 (15m)
    • 季节性: 否
    • 神经网络: 否
