Supertrend Ema Vol 策略

该策略结合 Supertrend、EMA 趋势确认以及成交量过滤。当 Supertrend 反转且价格位于 EMA 上下并且成交量超过其 EMA 时入场。使用 ATR 作为止损依据。

细节

  • 入场条件：
    • 多头：Supertrend 向上翻转，价格高于 EMA，成交量高于 Volume EMA
    • 空头：Supertrend 向下翻转，价格低于 EMA，成交量高于 Volume EMA
  • 多空方向：可配置
  • 出场条件：Supertrend 反转或 ATR 止损
  • 止损：ATR 倍数
  • 默认值：
    • AtrPeriod = 10
    • AtrMultiplier = 3m
    • EmaLength = 21
    • StartDate = new DateTimeOffset(2024, 1, 2, 0, 0, 0, TimeSpan.Zero)
    • AllowLong = true
    • AllowShort = false
    • SlMultiplier = 2m
    • UseVolumeFilter = true
    • VolumeEmaLength = 20
    • CandleType = TimeSpan.FromMinutes(1).TimeFrame()
  • 过滤：
    • 类别: Trend
    • 方向: Both
    • 指标: Supertrend, EMA, Volume EMA, ATR
    • 止损: ATR
    • 复杂度: Intermediate
    • 时间框架: Intraday
    • 季节性: No
    • 神经网络: No
    • 背离: No
    • 风险等级: Medium
