该策略是根据恩里科·马尔维尔蒂(Enrico Malverti)的文章改编而成,主要使用简单移动平均线(SMA)和相对强弱指标(RSI)来识别多头入场和平仓信号。策略只做多,不做空。
入场信号是当收盘价上穿较长周期的SMA均线时开多仓。
平仓信号有以下几种: 1. RSI指标下破70或超过75时平仓; 2. 收盘价下破较短周期的SMA均线时止损; 3. 收盘价下穿较短周期的SMA均线时止盈。
同时绘制了止损的SMA均线和止盈的SMA均线。
该策略具有以下优势:
该策略也存在一些风险:
对应方法:
1. 建立一个固定的追踪机制,不受心理影响;
2. 调整SMA均线的参数,优化周期;
3. 结合其他指标过滤RSI信号。
该策略还可以从以下几个方向进行优化:
该策略整体思路清晰易懂,使用基本指标,可控性较强,适合中长线操作。但参数设置和指标过滤都需要反复测试和优化,才能使策略更加稳定可靠。思路简单的策略也需要大量优化调整和丰富组合才能形成真正可用的交易系统。
