成交量枯竭策略

成交量的剧烈飙升常标志着行情的终结，因为交易者急于进出场。本策略将当前成交量与平均值比较以发现枯竭现象，结合蜡烛方向与均线过滤，寻找反转入场点。

测试表明年均收益约为 133%，该策略在加密市场表现最佳。

每根K线更新平均成交量。当新柱的成交量超过平均值的设定倍数，且蜡烛收盘方向与当前趋势相反时，系统入场交易，并以ATR为基础设定止损。

该策略预期在量能爆发后出现迅速反转，因此通常通过止损退出。

细节

  • 入场条件：成交量较平均值激增，且蜡烛方向与趋势相反。
  • 多/空：双向。
  • 退出条件：止损。
  • 止损：有，基于 ATR。
  • 默认值：
    • VolumePeriod = 20
    • VolumeMultiplier = 2.0
    • MAPeriod = 20
    • AtrMultiplier = 2 ATR
    • CandleType = 5 分钟
  • 过滤条件：
    • 类别: 反转
    • 方向: 双向
    • 指标: 成交量, 均线, ATR
    • 止损: 有
    • 复杂度: 中等
    • 时间框架: 日内
    • 季节性: 无
    • 神经网络: 无
    • 背离: 无
    • 风险级别: 中等
