概述
EMAC指数移动平均线交叉优化策略是在基础的EMAC策略上进行参数优化后的版本。该策略融合了趋势判断、多重均线过滤和止损止盈 Exit,旨在抓住中长线趋势进行趋势跟随。
策略原理
判断最近趋势方向:计算过去26周期的收盘价涨跌幅,判断为上升、下降、震荡。
多重均线过滤:计算10周期、20周期、34周期的EMA,待它们上穿50周期SMA时产生买入信号。
ATR止损:Entry信号出现时,止损位设为 Entry柱低点或高点减去2.5ATR。
移动止损:随价格上涨逐步向上移动止损线。
目标止盈:Entry信号出现时,设置目标位为当时收盘价加上3ATR。
MA均线回调止损Exit:当价格回破10日EMA时主动止损退出。
策略优势
多重均线过滤增加了信号的可靠性,避免被虚假突破误导。
采用ATR止损,可以根据市场波动性设置合理的止损距离。
移动止损使止损线逐步向上移动,保护了部分利润。
目标止盈设定合理的盈利目标,不贪心,避免把利润吐出。
MA回调Exit使得在趋势反转时能够及时止损退出。
策略风险及解决方法
在震荡行情中,EMA均线容易形成多次交叉对穿,可能会产生连续亏损的风险。可以适当调大EMA参数,或增加MA金叉过滤条件来降低这种概率。
ATR数值较大时,止损距离过大,亏损风险增加。可以考虑采用ATR的移动平均值或在ATR上乘以一个缩减比例系数来优化。
未考虑夜间隔空风险。可以加入夜间停牌时间段的判断逻辑,避免信号在不能交易的时间出现。
没有考虑大盘状态的影响。可以加入对大盘趋势的判断作为策略的开关条件之一,降低在大盘不利情况下的损失。
策略优化方向
可以测试不同长度的EMA参数组合,找到对不同品种更适合的均线长度。
可以测试ATR的移动平均值或系数缩减的方法来优化止损距离。
可以加入夜间停牌时间段判断逻辑,以规避隔夜风险。
可以加入对大盘态势的判断,设置对大盘趋势不利时的开关条件。
可以通过反向测试多年历史数据来选择参数组合,使策略在回测中具有最佳稳定性。
总结
EMAC指数移动平均线交叉优化策略结合趋势判断、多重均线过滤和动态止损止盈,旨在跟踪中长线趋势进行长线持有。相较于原始版本进行了参数优化,可望获得更好的实盘表现。但该策略仍需进一步优化与完善,加入更多逻辑判断以应对多种市场情况,降低实盘交易中的风险,提高策略的稳定性和盈利能力。
