该策略是一个基于复合均线的趋势跟踪和反转交易系统。它通过组合不同周期的移动平均线,结合价格对均线的反应来识别交易机会。策略的核心是通过观察价格与均线之间的关系以及价格回调到特定阈值时的反应来判断交易时机。
策略使用了多种移动平均线类型(EMA、TEMA、DEMA、WMA、SMA)的组合,通过两个不同周期(默认20和30)的加权或算术平均来构建复合均线。当价格在均线上方时认为是上升趋势,在均线下方时认为是下降趋势。策略会在趋势确立后等待价格回调到均线附近(通过反应百分比参数控制)时,如果出现反转信号则进行交易。具体来说,在上升趋势中,当价格回调到均线以下特定百分比并重新收于均线上方时开多;在下降趋势中,当价格反弹到均线以上特定百分比并重新收于均线下方时开空。
这是一个结合了趋势跟踪和反转交易理念的策略,通过复合均线和价格反应机制来捕捉交易机会。策略的核心优势在于其灵活性和对虚假信号的过滤能力,但同时也需要注意在不同市场环境下的参数优化问题。通过合理的风险控制和持续的优化改进,该策略有望在实际交易中取得稳定的收益。
