本策略是一个结合了斐波那契序列和布林带的创新交易系统。它通过将传统布林带的标准差倍数替换为斐波那契比率(1.618、2.618、4.236),形成了一个独特的价格波动区间判断系统。策略包含了完整的交易管理功能,包括止盈止损设置和交易时间窗口过滤,使其具有较强的实用性和灵活性。
策略的核心逻辑基于价格与斐波那契布林带的交互关系。首先计算价格的简单移动平均线(SMA)作为中轨,然后利用ATR乘以不同的斐波那契比率形成上下轨。当价格突破用户选定的斐波那契带位时,系统会产生交易信号。具体来说,当最低价低于目标买入带且最高价高于该带位时触发做多信号;当最低价低于目标卖出带且最高价高于该带位时触发做空信号。
这是一个将经典技术分析工具创新组合的策略,通过斐波那契序列优化了传统布林带策略。其主要优势在于自适应性和灵活性,但使用时需要注意参数选择和市场环境的匹配度。通过添加额外的确认指标和优化信号生成机制,该策略还有较大的改进空间。
