概述
该策略是基于平滑移动平均线与Stochastic指标的组合,目标是在趋势中捕获更多机会。它主要使用两条不同周期的指数移动平均线形成策略信号,结合Stochastic指标中的K线与D线的交叉作为入场时机选择,以期望在趋势中获得更高的盈利率。
策略原理
该策略使用12周期与26周期两条平滑移动平均线。当快线从下方上穿慢线时,做多;当快线从上方下穿慢线时,做空。为过滤假信号,它要求快线与慢线同向,快线在慢线之上才可做多,快线在慢线之下才可做空。
Stochastic指标中的K线与D线交叉作为入场时机选择。K线从超买线下方向上交叉D线时,做多;K线从超卖区下方向下交叉D线时,做空。
平滑移动平均线确定趋势方向,Stochastic指标过滤 Noise 并选择入场时机。它们的结合可以在趋势中获得更多获利机会。
策略优势
- 平滑移动平均策略本身就具有顺势而为特点,容易跟踪趋势
- 利用Stochastic指标过滤 Noise ,提高获利概率
- 快慢均线组合,当快线回调至慢线附近再入场,可获得更优博弈机会
- Stochastic指标中的K线与D线交叉组合使用,可进一步选择更佳入场点位
因此,该策略可顺势而为,有选择性地把握机会,从而获得更高的获利率。
风险分析
- 短期内离场风险较大。当快线回调至慢线时,可能会被否定信号或被套住
- 因其顺势而为的特性,行情剧烈反转时,无法快速适应,可能导致较大亏损
为降低这些风险,我们可以设置止损,或采用更宽松的移动平均线参数组合。
优化方向
该策略可从以下几个方面进行进一步优化:
- 测试不同移动平均线参数的组合,找到更佳的参数
- 测试不同Stochastic参数的组合
- 增加止损策略
- 增加基于波动率的动态止损
- 测试不同品种不同周期参数的组合优化
- 测试机器学习算法优化参数
通过测试不同的参数组合,可找到更强的参数;同时设立止损策略可有效降低风险,提高策略稳定性。
总结
该策略整合了平滑移动平均与Stochastic指标的优势,可顺势跟踪趋势,并选择更佳时机入场。它容易操作,风险可控,具有很大的实用价值。通过持续的测试与优化,其表现可得到进一步提升。它可为量化交易者提供一个高效稳定的趋势跟踪策略模型。
