本策略利用布林带的黄金分割线,结合均线形态判断进行回归交易。当价格接触布林带黄金分割线时看作买入信号,利用价格的均衡回归特征获得获利。
使用vwma而不是sma作为布林带的中轨,可以更好地反映价格的移动趋势
黄金分割是重要的支撑/阻力区域,这为回归提供依据
均线多头排列,确保大趋势向上
固定止损确保单笔损失控制
黄金分割线不是确定的支撑,价格可能直接跌穿
固定止损可能过于武断,应考虑根据市场波动调整
均线多头排列也可能是假突破,应结合更多指标判断
回归长度不确定,需要设定合理的止盈离场点
可以测试不同参数组合,如布林带周期、标准差倍数、固定止损百分比等
可以加入更多指标判断市场趋势和回归概率,如MACD、KD等
可以考虑动态止损,根据ATR止损或跟踪止损
可以优化止盈策略,如移动止盈、分批止盈等
本策略利用布林带黄金分割线进行均衡回归交易,具有交易逻辑清晰、参数设定简单、回撤可控等优点。但也存在一定的风险,需要进一步测试和优化,加入更多技术指标判断和止损/止盈工具,才能实际应用。总体来说,该策略提供了一种利用黄金分割法则进行量化交易的思路,值得进一步探索。
