本策略是一个基于斐波那契回撤和延展水平,结合EMA均线趋势判断的复合型量化交易系统。策略通过识别市场的重要支撑阻力位,结合趋势信号进行交易。系统使用20周期和50周期EMA均线判断市场趋势,并在此基础上利用斐波那契回撤水平寻找最佳交易机会。
策略的核心逻辑包含三个主要部分:首先计算近10个周期的最高价和最低价,用于确定价格波动区间;其次基于该区间计算五个关键的斐波那契回撤水平(0.236、0.382、0.5、0.618、0.786);最后通过20和50周期EMA的交叉确定趋势方向。在上升趋势中,当价格突破回撤水平时发出做多信号;在下降趋势中,当价格跌破回撤水平时发出做空信号。
该策略通过结合经典的技术分析工具,构建了一个相对完整的交易系统。虽然存在一些需要优化的地方,但整体框架具有良好的市场适应性。通过持续优化和改进,该策略有望在实际交易中取得更好的表现。建议在实盘交易前,进行充分的历史数据回测和参数优化。
