概述
该策略是一个基于10EMA和50EMA双重交叉的趋势追踪策略。它结合了小时线的10EMA作为辅助判断,在牛熊交替的市场中 dynamically 找到趋势方向,实现自动追踪止损。
策略原理
策略的核心逻辑是基于10EMA和50EMA的金叉死叉。具体来说,当10EMA从下方上穿50EMA形成金叉时,判断行情进入上涨趋势;当10EMA从上方下穿50EMA形成死叉时,判断行情进入下跌趋势。
在金叉死叉后的1-5根K线内开仓做多做空。此外,策略还引入小时线的10EMA作为辅助判断,只有当小时线的10EMA处于上升趋势时才在金叉后开多仓,只有小时线的10EMA处于下降趋势时才在死叉后开空仓,从而过滤掉部分假signals。
在开仓后,策略采用追踪止损+限价停利的出场方式。追踪止损能够锁定利润并最大限度确保交易盈利;限价停利确保在价格达到目标点时关闭头寸获得利润。
策略优势
该策略最大的优势在于利用EMA交叉判断主要趋势方向的同时,还引入辅助指标过滤信号,能有效地过滤假交叉从而提高信号的可靠性。此外双重EMA交叉结合追踪止损和限价止盈,既能最大化追踪趋势收益,又能有效控制交易风险,整体风险收益比良好。
相比单一指标策略,该策略能更准确判断趋势方向和 amplitudes。与传统止损止盈相比,该策略采用更为先进的追踪止损技术,能更好地锁定利润。
风险分析
该策略主要面临 intermittent whipsaw 和趋势反转的风险。当出现连续的假交叉信号时,可能导致策略被套利。此外,在开仓后价格反转也会产生损失。
为了降低 whipsaw 的风险,策略加入辅助指标进行信号过滤。为了控制趋势反转的风险,策略采用较为宽容的止损范围,同时限价止盈设置也能帮助减少此类风险。当止损被触发时,还可考虑重新进入趋势方向。
优化方向
该策略还有几个可优化的方向:第一,可以测试不同参数组合,如EMA周期、开仓延迟根数等,寻找最优参数;第二,可以引入更多辅助指标,如MACD、BOLL等进行信号过滤,提高信号质量;第三,可以优化止损止盈逻辑,如采用时间止损、振荡止损等其他止损方式;第四,可以结合更多行情条件开启策略交易,如只在某些时间段或涨跌幅度下触发信号等。
总结
该10EMA双重交叉趋势追踪策略,通过EMA golden cross 和 death cross 判断当前趋势方向,设置追踪止损和限价止盈来锁定利润和控制风险,同时结合辅助指标过滤信号提高信号质量,是一种较为完备的趋势交易策略。相比单一指标和传统止盈止损,该策略具有判断准确、止盈止损优化等优势,能够有效获取趋势收益的同时控制风险,是一种适合常规交易账户的策略。当然该策略也还有一定改进空间,通过参数优化、加入更多辅助指标等方式可进一步增强策略表现。
