概述
该策略通过计算移动平均线及其枢轴点,发现价格与移动平均线之间的背离,作为买入和卖出信号。它可以应用于任何振荡指标,以查找背离。这是一个有价值的工具,可以用来进行回测和实盘交易。
策略原理
- 计算长度为Len的移动平均线(MA)
- 检测MA的枢轴低点(PL)和枢轴高点(PH)
- 判断是否存在正向背离:价格创新低点而MA未创新低或价格未创新低而MA创新低
- 判断是否存在反向背离:价格创新高点而MA未创新高或价格未创新高而MA创新高
- 根据背离情况判断买入和卖出
优势分析
- 可自动发现价格与MA之间的背离,避免人工判断错误
- 可适用于任何振荡指标,扩展性强
- 可用于回测验证策略盈利能力
- 可配置参数调整灵敏度,避免错误信号
- 提供多种背离类型,判断准确全面
风险分析
- 若振荡指标设定不当,可能产生大量错误信号
- 背离发生前需要有效的枢轴点,可能发生信号不足
- 需适当调整参数,以平衡灵敏度与过滤错误信号
- 与其他因素结合使用效果更好,单独使用可信度较低
优化方向
- 优化移动平均线参数,寻找最佳参数组合
- 结合其他指标如量价指标避免错误信号
- 增加机器学习模型判断背离可信度
- 增加风险管理机制,控制单笔损失
总结
该策略通过发现价格与移动平均线之间的背离作为交易信号,可自动化判断,避免主观错误。可广泛适用于任何振荡指标,具备较强扩展性。需配合参数优化与其他指标使用,可大幅提高交易信号的可信度与系统稳定性。
