概述
该策略名为“基于转折点的RSI背离策略”(Pivot-based RSI Divergence Strategy)。它利用RSI指标在不同周期上的背离来判断买入卖出点,并在此基础上增加了长线RSI作为过滤条件,从而提高策略的稳定性。
策略原理
该策略主要判断短线RSI(如5日RSI)与价格出现“隐藏型多头背离”或“常规型多头背离”时机会买入;出现“隐藏型空头背离”或“常规型空头背离”时机会卖出。
所谓“常规型多头背离”是指:价格创新低而RSI未创新低;“隐藏型多头背离”则相反,价格未创新低而RSI创新低。两者定义中的“新低”和“新高”是相对于一定滚动窗口的历史极值而言的。
此外,策略还引入长线RSI(如50日RSI)作为过滤条件。只有当长RSI大于50时,才考虑买入信号;当长RSI小于30时,考虑止损或止盈退出。
策略优势
该策略最大的优势在于同时利用短线RSI的背离信号和长线RSI的过滤,能够在一定程度上避免被套和错过行情。具体来说,主要具有以下几个优势:
- 短线RSI背离信号能提前判断价格反转机会,及时捕捉行情转折点;
- 长线RSI过滤条件避免在趋势不确定时盲目做多;
- 多种类型的止盈方式,分批止盈有利于减少风险;
- Pyramiding机制允许加仓,进一步提高盈利空间。
策略风险
该策略也存在一些风险需要注意:
- RSI背离并不总是有效,有可能出现假信号;
- 加仓后风险会放大。如果判断错误,亏损会加速扩大;
- 止盈设置不当也可能导致过早止盈或盈利不足。
对应风险管理措施包括:合理设定止损止盈条件、控制每个头寸大小、分批减仓以平滑盈亏曲线等。
优化方向
该策略还存在进一步优化的空间:
- RSI参数可以进一步优化,找到最佳参数组合;
- 可以测试其他指标的背离信号,如MACD、KD等;
- 可以在特定品种(如原油、贵金属等)上专门优化参数,提高适应性。
总结
本策略综合运用短线与长线RSI的多空背离信号,在控制风险的同时,提高盈利效率。它体现了量化交易策略设计的多项原则,包括何时入场、何时离场、分批建仓减仓、设置止损止盈等。这是一个可供参考借鉴的RSI背离策略范例。
