该策略是基于双EMA指标和Bull Power指标的组合策略。策略名包含“量化”和“双管齐下”关键词,突出了其运用两个独立指标的特点。
该策略由两部分组成: 1. 2⁄20 EMA指标。该指标计算2日和20日的EMA,当价格从下方上穿EMA时产生买入信号,价格从上方下穿EMA时产生卖出信号。 2. Bull Power指标。该指标基于当前K线与前一K线的关系计算多空力量,当多空力量大于设置的阈值时产生相应的交易信号。
两部分信号需要同时触发才会打开仓位。比如EMA金叉和Bull Power同为正才开多仓,EMA死叉和Bull Power同为负才开空仓。
该策略通过双EMA和Bull Power的组合应用实现交易决策。相比单一指标,组合指标可以有效过滤假信号,在保持交易信号质量的同时,又具有参数调节空间。总体来说,该策略简单易懂,实际运用灵活,是一种实用性较强的量化交易策略。
