Lux Clara EMA + VWAP 策略

Lux Clara EMA + VWAP 策略利用快慢 EMA 的金叉/死叉，并结合 VWAP 和时间窗口过滤。当快 EMA 上穿慢 EMA 且慢 EMA 在 VWAP 之上并处于指定时段内时开多仓；相反条件下开空仓。EMAs 反向交叉时平仓。

细节

  • 入场条件：
    • 快 EMA 上穿慢 EMA，慢 EMA 高于 VWAP，当前时间在交易时段内。
    • 做空：快 EMA 下穿慢 EMA，慢 EMA 低于 VWAP，当前时间在交易时段内。
  • 方向：多空皆可。
  • 出场条件：
    • EMA 反向交叉。
  • 止损：无。
  • 默认参数：
    • FastEmaLength = 8
    • SlowEmaLength = 50
    • StartTime = 07:30
    • EndTime = 14:30
    • CandleType = 5 分钟
  • 过滤器：
    • 类型：趋势跟随
    • 方向：多空
    • 指标：EMA、VWAP
    • 止损：无
    • 复杂度：低
    • 时间框架：任意
    • 季节性：无
    • 神经网络：无
    • 背离：无
    • 风险等级：低
