RSI趋势反转策略是一个基于相对强弱指数(RSI)和平均真实波幅(ATR)的量化交易策略。该策略通过动态调整止盈止损(TP/SL)来适应快速的市场波动,捕捉趋势反转机会。策略以RSI为核心,结合ATR衡量波动率,构建上下两条自适应动态波段用作开仓平仓的依据。该策略可以独立使用,也可以作为其他策略的止盈止损模块。经过在特斯拉(TSLA)、苹果(AAPL)、英伟达(NVDA)等股票的15分钟级别数据回测,效果良好。
RSI趋势反转策略的核心在于动态止盈止损带的构建。首先利用自定义的highest_custom和lowest_custom函数找到自上次交叉以来的最高价和最低价,形成波段基础。然后分别计算长度为length的RSI和ATR,再进行如下计算: 1. 下轨 = 最高价 × [1 - (ATR/价格 + 1/(RSI下轨 × multiplier))] 2. 上轨 = 最低价 × [1 + (ATR/价格 + 1/(RSI上轨 × multiplier))]
其中multiplier为用户自定义的波段扩大因子。如果价格向上突破上轨则做多,向下跌破下轨则做空。同时这两条带子的颜色也根据价格相对波段的位置变化,便于观察。
RSI趋势反转策略利用RSI和ATR构建自适应波段,能够动态调整止盈止损点,及时应对市场变化。该策略逻辑清晰,适用范围广泛,可以作为量化交易者的有力工具。但在实际使用中仍需注意参数选择和风险控制,并建议与其他指标信号组合使用,提高整体表现。策略还有进一步的优化空间,如加入趋势过滤,参数寻优等。总的来说,RSI趋势反转策略为量化交易提供了一种简单而有效的思路。
